Component.run_parallel_command(args, cpus_per_task, ntasks, openmp_threads, logger, gpus=0, placement=None, gpus_per_task=None)[source]

Run a command using the active parallel system

Parameters:

  • args (list of str) – Command line arguments for the executable

  • cpus_per_task (int) – Number of CPUs per task

  • ntasks (int) – Number of parallel tasks

  • openmp_threads (int) – Number of OpenMP threads

  • logger (logging.Logger) – Logger to output command-line execution info

  • gpus (int, optional) – Number of GPUs this launch needs, as a total rather than a count per task

  • placement (mache.parallel.ResourcePlacement, optional) – The part of the allocation to confine this launch to. Passing none gives exactly the command Polaris has always built.

  • gpus_per_task (int, optional) –

    Number of GPUs per task

    Deprecated since version 1.1.0: Use gpus instead
