  • Publication number: 20210182070
    Abstract: A method uses an explicit resource file (ERF) to repetitively execute a set of processes using consistent resources. The method generates the ERF for a set of processes. The ERF identifies one or more specified central processing units (CPUs), one or more specified graphics processing units (GPUs), and one or more memory ranges in memory to be used by the one or more specified CPUs and the one or more specified GPUs when executing the set of processes. The method enforces compliance with the ERF when repetitively executing the set of processes.
