Method, system and device for executing simulation test task and medium

Abstract

The invention discloses a method, system and device for executing simulation test tasks and a storage medium, and the method comprises the steps: dividing the simulation test tasks into a plurality ofclusters according to the priority, and sequentially distributing the plurality of simulation test tasks in each cluster to different GPU nodes based on the priority sequence; judging whether the calculation amount of the simulation test task is greater than the calculation force of a single GPU node or not; in response to the fact that the calculation amount of the simulation test task is largerthan the calculation force of the single GPU node, segmenting the rendering part of the simulation test task to form a plurality of subtasks; and allocating the plurality of sub-tasks to the plurality of GPU nodes for execution. Aiming at the problem of high concurrency of simulation test tasks, the tasks are reasonably allocated, so that computing resources can be used to the maximum extent, thetask concurrency quantity is greatly increased, and the completion time of all the tasks is shortened.

Description

technical field [0001] The present invention relates to the field of testing, more specifically, to a method, system, computer equipment and readable medium for performing simulation testing tasks. Background technique [0002] For autonomous driving, simulation testing is the basic technology for technology verification, support system training, testing and verification. Autonomous driving simulation software can support functions such as road generation, scene definition, traffic flow simulation, control simulation, and sensor simulation. According to theoretical calculations, in order to verify the safety of self-driving cars and finally achieve mass production, tens of billions of self-driving test miles need to be accumulated, which requires companies to deploy at least 3 million self-driving vehicles for mileage in the next 10 years. Test to judge the safety of the vehicle in a series of environments such as day and night, sunny and rainy, urban and rural. This is unr...

AI Technical Summary

Problems solved by technology

[0003] Autonomous driving simulation software runs on a single computing device, and a single device can only perform one simulation task. The safety of autonomous vehicles requires the accumulation of tens of billions of autonomous driving test miles and millions of scene tasks for high-concurrency processing. , it will take a lot of time to rely on a single computing device; in addition, when multiple computing devices are used to conduct automatic driving simulation closed-loop tests, the simulation software on each computing device needs to be synchronized, which increases the difficulty of simulation
