Problems solved by technology

[0004] However, the memory channel affinity setting cannot guarantee that atomic tasks can be executed continuously
It is very likely that other tasks with the same task type and affinity will be inserted during the execution of the task, which will cause insufficient local memory space

Abstract

The invention relates to a task processing method and device, computer equipment and a storage medium. Atomic attribute nodes of a task sequence are identified, an atomic attribute task sequence is obtained based on the atomic attribute nodes, tasks contained in the atomic attribute task sequence are continuously executed on target equipment; due to the fact that each task in the atomic attribute task sequence can reuse the data on the devices, the method of the embodiment can not only reduce data exchange between the devices in the task execution process, but also reduce data copying when the tasks need to be continuously executed.

Description

technical field [0001] The present application relates to the technical field of computer equipment, in particular to a task processing method, device, computer equipment and storage medium. Background technique [0002] In many application scenarios, the output of one task is often the input of the next task, and these intermediate data are generally stored in local memory and are only visible to private processors. We refer to such tasks with the relationship that the output of one task is the input of the next task as atomic tasks in the task graph. [0003] In order to reuse these data and reduce data copying, it is hoped that these two tasks can run on one quadrant or even one processor, so that the previous task and the next task can be located in the same memory as much as possible through the memory channel affinity setting The quadrant the node is in. [0004] However, the memory channel affinity setting cannot guarantee that atomic tasks can be executed continuou...
