Embodiment Construction

[0066] First of all, some terms used in this application are explained in order to make those skilled in the art understand.

[0067] Computer system: a system integrating at least two heterogeneous devices, such as a chip integrating at least two heterogeneous devices, or a heterogeneous integrated platform integrating at least two heterogeneous devices.

[0068] Heterogeneous devices: different types of processing devices, for example, different types of processing devices such as CPU, GPU, FPGA, and ASIC may be called heterogeneous devices. In other embodiments of the present invention, when processing devices of the same type have different specifications, they may also be referred to as heterogeneous devices. For example, CPUs with different main frequencies may also be referred to as heterogeneous devices.

[0069] Task: Refers to an activity performed by software. A task can be either a process or a thread. In short, it refers to a series of operations that together a...

Abstract

The invention relates to the technical field of computers. The invention discloses a task processing method, a task processing device and a computer system. Implementation of the task processing method comprises the following steps: a first processing device generates a plurality of tasks and determines task description information of the plurality of tasks, and the task description information ofthe plurality of tasks is used for indicating a dependency relationship among the plurality of tasks, wherein in any two tasks with the dependency relationship, processing of one task needs to wait for a processing result of the other task; the first processing device sends an instruction to a second processing device, wherein the instruction comprises the plurality of tasks and task descriptioninformation of the plurality of tasks; and the second processing device receives the instruction and processes the plurality of tasks according to the dependency relationship among the plurality of tasks. Thus, the scheme in the embodiment of the invention can effectively reduce the waiting time delay, gives full play to the computing power of the acceleration chip, and improves the task processing efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a task processing method, a processing device, and a computer system. Background technique [0002] Today, with the rapid development of the information industry, computing requirements are becoming more and more abundant, and the computing performance of computers is constantly improving, and has developed from the past isomorphic computing to the current heterogeneous computing. Heterogeneous computing refers to the use of processors other than the central processing unit (CPU) to complete computing tasks. Different computing tasks may use different processors, such as: digital signal processing (digital signal processing, DSP), Graphics processing unit (GPU), field programmable gate array (field programmable gate array, FPGA), and neural network processor (neural network processing unit, NPU) that appeared in recent years. The NPU serves artificial intelligence (A...
