Detailed Description

Stub funcitons to allow produtil.mpi_impl to run when MPI is unavailable.

This module is part of the produtil.mpi_impl package. It underlies the produtil.run.openmp, produtil.run.mpirun , and produtil.run.mpiserial functions, providing the implementation needed to run when MPI is unavailable.

Functions
def	runsync
	Runs the "sync" command as an exe(). More...

def	openmp (arg, threads)
	Does nothing. More...

def	mpirunner (arg, kwargs)
	Raises an exception to indicate MPI is not supported. More...

def	can_run_mpi ()
	Returns False to indicate MPI is not supported. More...
