TECHNICAL AREA
[0001] At least one embodiment relates to processing resources used to execute and facilitate artificial intelligence. For example, at least one embodiment relates to processors or computer systems used to train neural networks to perform task and motion planning tasks as described herein. BACKGROUND
[0002] Training robots to perform actions can be very expensive and requires a high degree of human interaction. For example, a human operator must guide the robot to perform specific tasks so the robot can learn and reward the robot for correctly performed tasks. Furthermore, even after training, information about the environment is needed for a trained robot to perform actions correctly. Therefore, better ways are needed to train an autonomous device to perform actions better.

In at least one embodiment, a joint space may specify a coordinate space of a joint of an autonomous device 114. In at least one embodiment, joint trajectories are executed on an autonomous device. In at least one embodiment, a joint state of an autonomous device and training actions performed by an autonomous device are recorded for each point in time. For example, in at least one embodiment, a joint state of an autonomous device and training actions performed by an autonomous device are recorded every second.In at least one embodiment, the planning module 106 outputs one or more training actions 108 represented by one or more common control commands used to control one or more control inputs that control or otherwise influence one or more angles of one or more joints of the autonomous device 114. For example, in at least one embodiment, common control commands may be used to control one or more joints of a robot (e.g., a robot arm).
[0013] In at least one embodiment, the planning module 106 is to access a state of an environment in one or more simulations. In at least one embodiment, the planning module 106 may access information indicative of a state of an environment without performing object detection (e.g., detecting objects in images). In at least one embodiment, the planning module 106 uses one or more guided tasks, resulting in planning going hand in hand with gathering visual information about an environment. In at least one embodiment, the planning module 106 may gather essentially everything from the environment. For example, in at least one embodiment, the planning module 106 may gather an initial state of the environment, such as the positions of all objects and / or the attitude of all objects.For example, in at least one embodiment, the planning module 106 may capture the initial state of an autonomous device, such as position, attitude, joint positions of the autonomous device.
[0014] In at least one embodiment, the planning module 106 is intended to simulate an initial state of an environment. In at least one embodiment, the planning module 106 utilizes privileged latent information about a state of an environment to select an executable action for an autonomous device.

[0016] In at least one embodiment, training actions 108 include one or more actions to change an initial state of an environment, such as the initial state of environment 102. For example, in at least one embodiment, performing a training action is to move a cup from a first position on a table to a second position on the table. In at least one embodiment, in such an example, a final state of an environment is a cup in a second position (different from a first position) on a table.

In at least one embodiment, a training action may, for example, specify a grasp of a robot hand, represented as a discrete indicator variable of zero, one, or minus one. In at least one embodiment, the training actions are high-level and / or low-level training actions. In at least one embodiment, high-level training actions relate to selecting an action, for example, based on the color or shape of an object.In at least one embodiment, low-level training actions relate to the execution of an action, for example, the position of an object. In at least one embodiment, a pose of an object may be estimated. For example, in at least one embodiment, the planning module 106 estimates the position of an object, for example, a handle of a cup. In at least one embodiment, an estimated pose is constructed from a perspective of the autonomous device 114. For example, in at least one embodiment, the planning module 106 estimates the position of an object relative to the position of a gripper of the autonomous device 114.

[0019] In at least one embodiment, the training actions 108 are filtered. In at least one embodiment, the training actions 108 are filtered to improve a selection of the data generated by the planning module 106. For example, in at least one embodiment, the training actions 108 may be filtered such that filtered training actions are easier to perform for a simulation. For example, in at least one embodiment, training actions 108 may have values that lie outside a preferred distribution when generated with the planning module 108 (for example, when the planning module 108 uses randomized algorithms for motion planning). In at least one embodiment, the training actions 108 are filtered based on a workspace constraint and a trajectory length constraint to provide more optimal actions for learning.
[0020] In at least one embodiment, post-processing is applied to the training action 108. For example, in at least one embodiment, one or more post-processing operations may be performed to generate a training action 108 suitable for training the neural network 118. In at least one embodiment, the training actions 108 are generated such that the cost of clean training actions is minimized. In at least one embodiment, the training actions 108 are selected by screening out bad training actions. In at least one embodiment, the screening out of bad training actions is performed by a human.
[0021] In at least one embodiment, software (e.g., one or more software programs) may receive training actions generated by the planning module. In at least one embodiment, software may modify the training actions generated by the planning module. In at least one embodiment, the modified training actions may be received by an autonomous device. In at least one embodiment, the autonomous device may perform modified training actions.

In at least one embodiment, the training actions include one or more actions that an autonomous device is permitted to perform.In at least one embodiment, a permitted training action for the autonomous device may include, for example, moving so that it does not collide with other objects and / or rules for grasping and / or releasing objects.

In at least one embodiment, an open-loop plan includes positions where a robot arm with a gripper can move, such as gripper actions for grasping or releasing. In at least one embodiment, an open-loop plan encodes waypoints and grasp points. In at least one embodiment, the planning module 106 does not change an open-loop plan when an environment changes. In at least one embodiment, the planning module 106 changes an open-loop plan during replanning. In at least one embodiment, the planning module 106 provides an open-loop plan with waypoints during training.In at least one embodiment, the goal of an autonomous device is to reach waypoints, regardless of the current position of the autonomous device. In at least one embodiment, commands given to an autonomous device to reach waypoints are recorded sequentially.
[0023] In at least one embodiment, the autonomous device 114 includes one or more components configured to perform one or more autonomous tasks. In at least one embodiment, the autonomous device 114 is equipped with the planning module 106. In at least one embodiment, the autonomous device 114 interacts with objects in an environment. For example, in at least one embodiment, the autonomous device 114 picks up and places items or opens a door. In at least one embodiment, a video of these interactions is recorded at specific times.

[0024] In at least one embodiment, image sensor 122 includes one or more components configured to generate one or more images. In at least one embodiment, image sensor 122 observes images 120 of training actions performed by autonomous device 114. In at least one embodiment, a virtual image sensor may observe changes in a state of the environment during the simulation.

In at least one embodiment, a virtual image sensor may render images of a state of the environment.
[0025] In at least one embodiment, training actions are modified to include images obtained from an image sensor to enhance training of a neural network. In at least one embodiment, an autonomous device performs actions observed over a history of frames in the video.
[0026] In at least one embodiment, a neural network does not change a state of an environment during training because a neural network does not have access to exact positions of objects in an environment during training. In at least one embodiment, a neural network uses images as a proxy to attempt to infer the state of the environment during training and therefore uses previous video frames to infer the state of the environment during training. In at least one embodiment, previous video frames are input to a neural network during training. In at least one embodiment, a video is a surrogate for a state of the environment. In at least one embodiment, observed states of the environment or images are used to detect a state of the environment.
[0027] In at least one embodiment, an image sensor may be a camera. In at least one embodiment, images are captured by an image sensor at any given time.

[0028] In at least one embodiment, an image of how an autonomous device reached a next waypoint is recorded when a waypoint is reached.

[0035] In at least one embodiment, the neural network 118 outputs robot actions. However, in at least one embodiment, the system 100 does not need to rely on the training actions 108 generated by the planning module 106 because the training actions 108 generated by a planning module 106 are modified with images 120.
[0036] In at least one embodiment, neural network 118 outputs a command to control an inductor. In at least one embodiment, neural network 118 enables high-frequency controls that command multiple actions simultaneously.

[0037] In at least one embodiment, neural network 118 includes an output layer that uses a Gaussian mixture model. In at least one embodiment, a planning module executes in a cost minimization mode, wherein a planning module is configured to find a low-cost solution relative to minimizing time.

In at least one embodiment, a neural network repeats a process until a final state of the environment is reached or repeats steps until a certain condition is met.
[0040] In at least one embodiment, the autonomous device 114 equipped with a neural network 118 can be deployed in an unknown environment without human supervision because the neural network 118 automatically generates training actions.

[0189] In at least one embodiment, conventional ADAS systems may be prone to false positives, which may be annoying and distracting for a driver, but are typically not catastrophic because conventional ADAS systems warn a driver and allow that driver to decide whether a safety condition actually exists and act accordingly. In at least one embodiment, even in the presence of conflicting results, the vehicle 1000 decides whether to follow the result of a primary computer or a secondary computer (e.g., a first controller or a second controller of controls 1036).

[0190] In at least one embodiment, a primary computer may be configured to provide a monitoring MCU with a confidence score indicating the primary computer's confidence in a selected result. In at least one embodiment, if that confidence score exceeds a threshold, that monitoring MCU may follow that primary computer's instruction, regardless of whether that secondary computer provides a conflicting or inconsistent result.

[0191] In at least one embodiment, a monitoring MCU may be configured to execute one or more neural networks trained and configured to determine, based at least in part on outputs from a primary computer and outputs from a secondary computer, conditions under which that secondary computer will provide false alarms. In at least one embodiment, neural networks in a monitoring MCU may learn when the output of a secondary computer is trustworthy and when it is not. For example, in at least one embodiment, if that secondary computer is a radar-based FCW system, one or more neural networks in that monitoring MCU may learn when an FCW system identifies metallic objects that do not actually pose a threat, such as a drainage grate or manhole cover, which triggers an alarm.In at least one embodiment, when a secondary computer is a camera-based LDW system, a neural network in a supervising MCU may learn to override LDW when cyclists or pedestrians are present and lane departure is actually the safest maneuver.

In at least one embodiment, this secondary computer may use classic computer vision rules (if-then), and the presence of one or more neural networks in a supervising MCU may improve reliability, safety, and performance. For example, in at least one embodiment, different implementations and intentional non-identity make an overall system more fault-tolerant, particularly against errors caused by software (or software-hardware interface) functionality.For example, in at least one embodiment, a monitoring MCU may have greater assurance regarding the correctness of an overall result when there is a software bug or error in software executing on a primary computer and non-identical software code executing on a secondary computer produces a consistent overall result, and a bug in the software or hardware on that primary computer does not cause a significant error.
[0193] In at least one embodiment, an output of the ADAS system 1038 may be fed into the perception block of a primary computer and / or the dynamic task block of a primary computer. For example, in at least one embodiment, if the ADAS system 1038 indicates a forward crash warning due to an object immediately ahead of the vehicle, a perception block may use this information in identifying objects. In at least one embodiment, a secondary computer may have its own neural network trained, thus reducing the risk of false alarms as described herein.

[0242] In at least one embodiment, virtual / effective addresses from a graphics processing engine 1531 are translated into real / physical addresses in system memory 1514 by an MMU 1539. In at least one embodiment, accelerator integration circuitry 1536 supports multiple (e.g., 4, 8, 16) graphics acceleration modules 1546 and / or other accelerator devices. In at least one embodiment, graphics acceleration module 1546 may be associated with a single application executing on processor 1507 or shared among multiple applications. In at least one embodiment, a virtualized environment for graphics execution is depicted in which resources from graphics processing engines 1531(1)-1531(N) are shared with multiple applications or virtual machines (VMs).In at least one embodiment, resources may be divided into "slices" that are allocated to different VMs and / or applications based on processing requirements and priorities associated with VMs and / or applications.
[0243] In at least one embodiment, accelerator integration circuitry 1536 acts as a bridge to a system for graphics acceleration module 1546 and provides address translation and system memory caching services. Additionally, in at least one embodiment, accelerator integration circuitry 1536 may provide virtualization facilities to a host processor to manage the virtualization of graphics processing engines 1531(1)-1531(N), interrupts, and memory management.
[0244] In at least one embodiment, each host processor can directly access these resources via an effective address because the hardware resources of graphics processing engines 1531(1)-1531(N) are explicitly mapped to a real address space seen by host processor 1507. In at least one embodiment, a function of accelerator integration circuitry 1536 is to physically separate graphics processing engines 1531(1)-1531(N) so that they appear to a system as independent entities.
[0245] In at least one embodiment, one or more graphics memories 1533(1)-1533(M) are coupled to each of the graphics processing engines 1531(1)-1531(N), where N=M. In at least one embodiment, graphics memories 1533(1)-1533(M) store instructions and data processed by each of the graphics processing engines 1531(1)-1531(N). In at least one embodiment, the graphics memories 1533(1)-1533(M) may be volatile memories such as DRAMs (including stacked DRAMs), GDDR memories (e.g., GDDR5, GDDR6), or HBM, and / or non-volatile memories such as 3D XPoint or Nano-RAM.
[0246] In at least one embodiment, biasing techniques may be used to reduce data traffic over high-speed interconnect 1540 and ensure that the data stored in graphics memories 1533(1)-1533(M) is the data most frequently used by graphics processing engines 1531(1)-1531(N) and preferably not used (at least not frequently) by cores 1560A-1560D. In at least one embodiment, a biasing mechanism attempts to keep data needed by cores (and preferably not by graphics processing engines 1531(1)-1531(N)) in caches 1562A-1562D, 1556, and system memory 1514.
[0247] Fig. 15C shows another exemplary embodiment in which accelerator integration circuitry 1536 is integrated with processor 1507. In this embodiment, graphics processing engines 1531(1)-1531(N) communicate directly over a high-speed interconnect 1540 with accelerator integration circuitry 1536 via an interface 1537 and an interface 1535 (which may again be any form of bus or interface protocol). In at least one embodiment, accelerator integration circuitry 1536 may perform similar operations as described with respect to Fig. 15B, but possibly with higher throughput due to its proximity to the coherence bus 1564 and caches 1562A-1562D, 1556. In at least one embodiment, an accelerator integration circuit supports different programming models, including a dedicated process programming model (no graphics acceleration module virtualization) and shared programming models (with virtualization), which may include programming models controlled by the accelerator integration circuit 1536 and programming models controlled by the graphics acceleration module 1546.
[0248] In at least one embodiment, graphics processing engines 1531(1)-1531(N) are associated with a single application or process under a single operating system. In at least one embodiment, a single application can forward other application requests to graphics processing engines 1531(1)-1531(N), thereby providing virtualization within a VM / partition.
[0249] In at least one embodiment, graphics processing engines 1531(1)-1531(N) may be shared between multiple VM / application partitions. In at least one embodiment, shared models may use a system hypervisor to virtualize graphics processing engines 1531(1)-1531(N) to provide access by any operating system. In at least one embodiment, for systems with a partition without a hypervisor, graphics processing engines 1531(1)-1531(N) are owned by an operating system. In at least one embodiment, an operating system may virtualize graphics processing engines 1531(1)-1531(N) to provide access to any process or application.
[0250] In at least one embodiment, the graphics acceleration module 1546 or an individual graphics processing engine 1531(1)-1531(N) selects a process element using a process handle. In at least one embodiment, process elements are stored in system memory 1514 and are addressable using an effective address to real address translation technique described herein. In at least one embodiment, a process handle may be an implementation-specific value provided to a host process when it registers its context with the graphics processing engine 1531(1)-1531(N) (i.e., calls system software to add a process element to a process element linked list). In at least one embodiment, the lower 16 bits of a process handle may be an offset of a process element within a process element linked list.
[0251] Fig. 15D illustrates an exemplary accelerator integration slice 1590. In at least one embodiment, a "slice" comprises a particular portion of the processing resources of accelerator integration circuitry 1536. In at least one embodiment, an application is effective addresses 1582 within system memory 1514 in which process elements 1583 are stored. In at least one embodiment, process elements 1583 are stored in response to GPU calls 1581 from applications 1580 executing on processor 1507. In at least one embodiment, a process element 1583 contains process state for a corresponding application 1580. In at least one embodiment, a work description (WD) 1584 contained in a process element 1583 may be a single job requested by an application or may contain a pointer to a queue of jobs.In at least one embodiment, WD 1584 is a pointer to a job request queue at the effective address 1582 of an application.
[0252] In at least one embodiment, the graphics acceleration module 1546 and / or individual graphics processing engines 1531(1)-1531(N) may be shared by all or a subset of processes in a system. In at least one embodiment, an infrastructure for establishing states of processes and sending a WD 1584 to a graphics acceleration module 1546 to start a job in a virtualized environment may be included.
[0253] In at least one embodiment, a dedicated process programming model is implementation-specific. In at least one embodiment, in this model, a graphics acceleration module 1546 or a single graphics processing engine 1531 is owned by a single process. In at least one embodiment, when the graphics acceleration module 1546 is owned by a single process, a hypervisor initializes the accelerator integration circuit 1536 for an owning partition, and an operating system initializes the accelerator integration circuit 1536 for an owning process when the graphics acceleration module 1546 is allocated.
[0254] In at least one embodiment, a WD fetch unit 1591 in an accelerator integration slice 1590 fetches the next WD 1584, which contains an indication of the work to be performed by one or more graphics processing engines of the graphics acceleration module 1546. In at least one embodiment, data from WD 1584 may be stored in registers 1545 and used by MMU 1539, interrupt management circuitry 1547, and / or context management circuitry 1548, as shown. For example, one embodiment of MMU 1539 includes segment / page walk circuitry for accessing segment / page tables 1586 within an operating system virtual address space 1585. In at least one embodiment, interrupt management circuitry 1547 may process interrupt events 1592 received from graphics acceleration module 1546.In at least one embodiment, when performing graphics operations, an effective address 1593 generated by a graphics processing engine 1531(1)-1531(N) is translated into a real address by the MMU 1539.
[0255] In at least one embodiment, registers 1545 are duplicated for each graphics processing engine 1531(1)-1531(N) and / or each graphics acceleration module 1546 and may be initialized by a hypervisor or an operating system. In at least one embodiment, each of these duplicated registers may be included in an accelerator integration slice 1590. Example registers that may be initialized by a hypervisor are listed in Table 1. Table 1 - Registers initialized by a hypervisor Register # Beschreibung 1 Slice-Steuerregister (Slice-Steuerregister) 2 Reale Adresse (RA) Zeiger auf den Bereich für geplante Prozesse 3 Authority mask override register 4 Interrupt vector table entry offset 5 Interrupt vector table entry boundary 6 Condition register 7 Logical partition ID 8 Real Address (RA) pointer to Hypervisor Accelerator Utilization Record 9 Memory description register
[0256] Table 2 lists example registers that can be initialized by an operating system. Table 2 - Initialized operating system registers Register # Description 1 Process and thread identification 2 Effective Address (EA) Context Store / Restore Pointer 3 Virtual Address (VA) pointer for the accelerator utilization set 4 Virtual Address (VA) Pointer to the memory segment table 5 Authority mask 6 Job description
[0257] In at least one embodiment, each WD 1584 is specific to a particular graphics acceleration module 1546 and / or graphics processing engines 1531(1)-1531(N). In at least one embodiment, it contains all the information a graphics processing engine 1531(1)-1531(N) needs to perform its work, or it may be a pointer to a memory location where an application has set up a command queue for work to be performed.
[0258] Fig.15E shows additional details for an exemplary embodiment of a shared model. This embodiment includes a real hypervisor address space 1598 in which a process element list 1599 is stored. In at least one embodiment, the real hypervisor address space 1598 is accessible via a hypervisor 1596 that virtualizes graphics acceleration engine engines for the operating system 1595.
[0259] In at least one embodiment, shared programming models enable all or a subset of processes from all or a subset of partitions in a system to use a graphics acceleration module 1546. In at least one embodiment, there are two programming models where the graphics acceleration module 1546 is shared among multiple processes and partitions: time-shared and graphics-shared.
[0260] In at least one embodiment, in this model, the graphics acceleration module 1546 belongs to the system hypervisor 1596 and provides its functionality to all operating systems 1595. In at least one embodiment, in order to support virtualization by the system hypervisor 1596, a graphics acceleration module 1546 may meet certain requirements, such as (1) the job request of an application must be autonomous (i.e.the state does not need to be maintained between jobs), or the graphics acceleration module 1546 must provide a mechanism for saving and restoring the context, (2) an application's job request is guaranteed by the graphics acceleration module 1546 to complete in a certain time, including any translation errors, or the graphics acceleration module 1546 provides the ability to interrupt the processing of a job, and (3) the graphics acceleration module 1546 must ensure fairness between processes when operating in a directed joint programming model.
[0261] In at least one embodiment, application 1580 is required to execute an operating system system call 1595 with a graphics acceleration module type, a work description (WD), an authority mask register (AMR) value, and a context save / restore region (CSRP) pointer. In at least one embodiment, the graphics acceleration module type describes a targeted acceleration function for a system call. In at least one embodiment, the graphics acceleration module type may be a system-specific value.In at least one embodiment, WD is specifically formatted for the graphics acceleration module 1546 and may be in the form of an instruction of the graphics acceleration module 1546, a pointer to an effective address of a user-defined structure, a pointer to an effective address of a queue of instructions, or any other data structure to describe the work to be performed by the graphics acceleration module 1546.
[0262] In at least one embodiment, an AMR value is an AMR state to be used for a current process. In at least one embodiment, a value passed to an operating system is similar to an application setting an AMR. In at least one embodiment, if the implementations of accelerator integration circuitry 1536 (not shown) and graphics acceleration module 1546 do not support a user authority mask override register (UAMOR), an operating system may apply a current UAMOR value to an AMR value before passing an AMR in a hypervisor call. In at least one embodiment, hypervisor 1596 may optionally apply a current authority mask override register (AMOR) value before placing an AMR in process element 1583.In at least one embodiment, CSRP is one of the registers 1545 that contains an effective address of a region in an application's effective address space 1582 for the graphics acceleration module 1546 to save and restore context state. In at least one embodiment, this pointer is optional if no state needs to be saved between jobs or when a job is interrupted. In at least one embodiment, the context save / restore region may be pinned system memory.
[0263] Upon receiving a system call, the operating system 1595 may verify whether the application 1580 is registered and has been granted permission to use the graphics acceleration module 1546. In at least one embodiment, the operating system 1595 then calls the hypervisor 1596 with the information shown in Table 3. Table 3 - Parameters for calling the operating system to the hypervisor Parameters # Description 1 A job description (WD) 2 An authority mask register (AMR) value (possibly masked) 3 An effective address (EA) Context save / restore pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) accelerator utilization set pointer (AURP) 6 Virtual address of the pointer to the memory segment table (SSTP) 7 A logical interrupt service number (LISN)
[0264] In at least one embodiment, upon receiving a hypervisor call, hypervisor 1596 checks whether operating system 1595 is registered and has been granted permission to use graphics acceleration module 1546. In at least one embodiment, hypervisor 1596 then inserts process element 1583 into a process element linked list for a corresponding graphics acceleration module type 1546. In at least one embodiment, a process element may include the information shown in Table 4. Table 4 - Process element information Item # Description 1 A job description (WD) 2 An Authority Mask Register (AMR) value (possibly masked). 3 An effective address (EA) Context save / restore pointer (CSRP) 4 A process ID (PID) and optionally a thread ID (TID) 5 A virtual address (VA) accelerator utilization set pointer (AURP) 6 Virtual address of the pointer to the memory segment table (SSTP) 7 A logical interrupt service number (LISN) 8 Interrupt vector table derived from hypervisor call parameters 9 A status register value (SR) 10 A logical partition ID (LPID) 11 A pointer to the hypervisor's accelerator utilization set with real address (RA) 12 Memory Description Register (SDR)
[0265] In at least one embodiment, the hypervisor initializes a plurality of accelerator integration slice 1590 registers 1545.
[0266] As in Fig.15F, in at least one embodiment, a unified memory addressable via a common virtual memory address space is used to access physical processor memories 1501(1)-1501(N) and GPU memories 1520(1)-1520(N). In this implementation, operations performed on GPUs 1510(1)-1510(N) use the same virtual / effective memory address space to access processor memories 1501(1)-1501(M) and vice versa, thereby simplifying programmability. In at least one embodiment, a first portion of a virtual / effective address space is assigned to processor memory 1501(1), a second portion is assigned to second processor memory 1501(N), a third portion is assigned to GPU memory 1520(1), and so on.In at least one embodiment, this distributes a total virtual / effective memory space (sometimes referred to as effective address space) across each of the processor memories 1501 and GPU memories 1520, such that each processor or GPU can access each physical memory with a virtual address associated with that memory.
[0267] In at least one embodiment, a bias / coherence management circuit 1594A-1594E in one or more MMUs 1539A-1539E ensures cache coherence between caches of one or more host processors (e.g., 1505) and GPUs 1510 and implements biasing techniques that indicate physical memories in which certain data types should be stored. In at least one embodiment, while multiple instances of bias / coherence management circuits 1594A-1594E in Fig.15F, bias / coherence circuits may be implemented within an MMU of one or more host processors 1505 and / or within an accelerator integration circuit 1536.
[0268] One embodiment enables GPU memory 1520 to be mapped as part of system memory and accessed using Shared Virtual Memory (SVM) technology, but without the performance penalty associated with full system cache coherence. In at least one embodiment, the ability to access GPU memory 1520 as system memory without burdensome cache coherence overhead provides a beneficial environment for GPU offloading. In at least one embodiment, this arrangement enables host processor 1505 software to set up operands and access computation results without the overhead of traditional I / O DMA data copies. In at least one embodiment, such traditional copies include calls to drivers, interrupts, and memory I / O accesses (MMIO), all of which are inefficient compared to simple memory accesses.In at least one embodiment, the ability to access GPU memory 1520 without cache coherence overhead may be critical to the execution time of a paged computation. For example, in at least one embodiment, in cases with significant streaming write memory traffic, the cache coherence overhead may significantly reduce the effective write bandwidth seen by a GPU 1510. In at least one embodiment, operand facility efficiency, result access efficiency, and GPU computation efficiency may play a role in determining the effectiveness of GPU paged computation.
[0269] In at least one embodiment, the selection of the GPU bias and the host processor bias is controlled by a bias tracker data structure. For example, in at least one embodiment, a bias table may be used, which may be a page-granular structure (e.g., controlled at a memory page granularity) comprising 1 or 2 bits per GPU-attached memory page. In at least one embodiment, a bias table may be implemented in a stolen memory region of one or more GPU memories 1520, with or without a bias cache in a GPU 1510 (e.g., to cache frequently / recently used bias table entries). Alternatively, in at least one embodiment, an entire bias table may be maintained within a GPU.
[0270] In at least one embodiment, a bias table entry associated with each access to GPU-attached memory 1520 is accessed prior to the actual GPU memory access, thereby triggering subsequent operations. In at least one embodiment, local requests from a GPU 1510 that find their page in the GPU bias are forwarded directly to a corresponding GPU memory 1520. In at least one embodiment, local requests from a GPU that find their page in the host bias are forwarded to the processor 1505 (e.g., over a high-speed interconnect as described herein). In at least one embodiment, requests from the processor 1505 that find a requested page in the host processor bias complete a request like a normal memory read.Alternatively, requests directed to a GPU-biased page may be forwarded to a GPU 1510. In at least one embodiment, a GPU may then transition a page to host processor bias if it is not currently using a page. In at least one embodiment, a page's bias state may be changed either through a software-based mechanism, a hardware-assisted software-based mechanism, or, in a limited number of cases, a purely hardware-based mechanism.
[0271] In at least one embodiment, a mechanism for changing bias state uses an API call (e.g., OpenCL), which in turn invokes a driver for a GPU, which in turn sends a message (or queues a command descriptor) to a GPU instructing it to change a bias state and, on some transitions, perform a cache flush operation in a host. In at least one embodiment, a cache flush operation is used for a transition from host processor 1505 bias to GPU bias, but not for an opposite transition.
[0272] In at least one embodiment, cache coherence is maintained by temporarily making GPU-biased pages uncacheable by host processor 1505. In at least one embodiment, to access these pages, processor 1505 may request access from GPU 1510, which may or may not grant access immediately. Therefore, in at least one embodiment, to reduce communication between processor 1505 and GPU 1510, it is advantageous to ensure that GPU-biased pages are those required by a GPU but not by host processor 1505, and vice versa.
