std::shared_ptr<MPIAction> addMPIAction(const std::string &name, const std::function<void(const std::shared_ptr<ExecutionController> &controller)> &mpi_code, unsigned long num_processes, unsigned long num_cores_per_process)

Add an MPI action to the job. The intended use-case for an MPI action is that never runs concurrently with other actions within its job, and that that job is submitted to a BatchComputeService, so that it has a set of resources dedicated to it. If the job is submitted to a BareMetalComputeService, this action will use all of that service’s resources, regardless of other running actions/jobs on that service.

Parameters:

  • name – the action’s name (if empty, a unique name will be picked for you)

  • mpi_code – a lambda/function that implements the MPI code that MPI processes should execute

  • num_processes – the number of MPI processes that will be started.

  • num_cores_per_process – the number of core that each MPI process should use. Note that this is not enforced by the runtime system. If the processes compute with more cores, then they will cause time-sharing on cores.

Returns:

an MPI action
