Embodiment 1

[0031] figure 1 It shows the implementation process of the collaborative scheduling method based on the GPGPU architecture provided by Embodiment 2 of the present invention, and the method process is described in detail as follows:

[0032] In step S101, the two priority scheduling queues in the Issue stage are merged into one priority scheduling queue, and the merged priority scheduling queue is used as the priority scheduling queue in the Fetch stage;

[0033] In step S102, in the Fetch stage, an instruction is obtained from the merged priority scheduling queue;

[0034] In step S103, the acquired instruction is decoded;

[0035] In step S104, in the Issue stage, the decoded instructions are executed in parallel by the two schedulers in the Issue stage, and the decoded instructions are launched according to the respective scheduling policies of the schedulers;

[0036] In step S105, execution starts after the issued instruction enters the pipeline;

[0037] In step S106, ...

Abstract

The invention belongs to the technical field of high-performance computers and provides a collaborative scheduling method and system based on a GPGPU system structure. The collaborative scheduling method comprises the steps that two priority scheduling queues are combined into one priority scheduling queue in an Issue stage, and the priority scheduling queue formed after combination is used as a priority scheduling queue in a Fetch stage; in the Fetch stage, instructions are obtained from the priority scheduling queue formed after combination; the obtained instructions are decoded; in the Issue stage, parallel execution of the decoded instructions is conducted through two schedulers in the Issue stage, and the decoded instructions are transmitted according to the respective scheduling strategies of the schedulers; after the transmitted instructions enter an assembly line, execution is conducted; an execution result of the instructions are written to a specific position. By the adoption of the collaborative scheduling method and system based on the GPGPU system structure, the GPGPU performance can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of high-performance computing, and in particular relates to a collaborative scheduling method and system based on the GPGPU architecture. Background technique [0002] General Purpose Graphic Processing Unit (GPGPU) is a high-performance, parallel computing processor. [0003] From the perspective of hardware resources, take NVIDIA's Fermi architecture GPGPU as an example. It is a separate larger board on the hardware, which is connected to the host system by a PCI slot. Microscopically, GPGPU contains several SMs. SM means Streaming MultiProcessor in Chinese, which means stream multiprocessor. Each SM is an independent action unit on the hardware. Each SM can contain several SPs. SP refers to Scalar Processor, which is a computing unit of hardware. In addition to SP, the computing unit also includes several SFU computing units. SFU is a component used to complete special computing functions. In addition t...
