Detailed Description

Adds support for LSF+aprun with the Intel OpenMP to produtil.run.

This module is part of the mpi_impl package – see produtil.mpi_impl for details. This implements the bizarre combination of LSF, Cray aprun with Intel OpenMP.

Classes
class	Syncer
	Calls sync and aprun -B sync. More...

Functions
def	runsync
	Runs the "sync" command as an exe(). More...
def	openmp (arg, threads)
	Adds OpenMP support to the provided object. More...
def	aprun_ln_sf
def	detect ()
	Determines if Cray aprun should be used to run MPI programs by looking for the aprun program in $PATH.
def	can_run_mpi ()
	Does this module represent an MPI implementation? Returns True. More...
def	make_bigexe (exe, kwargs)
	Returns an ImmutableRunner that will run the specified program. More...
def	mpirunner (arg, allranks=False, logger=None, kwargs)
def	mpirunner2 (arg, allranks=False, logger=None, kwargs)
	Turns a produtil.mpiprog.MPIRanksBase tree into a produtil.prog.Runner. More...

Variables
tuple	module_logger = logging.getLogger('lsf_cray_intel')
tuple	aprun_path = produtil.fileop.find_exe('aprun',raise_missing=False)

Function Documentation

def produtil.mpi_impl.lsf_cray_intel.can_run_mpi

(

)

Does this module represent an MPI implementation? Returns True.

Definition at line 88 of file lsf_cray_intel.py.

def produtil.mpi_impl.lsf_cray_intel.make_bigexe	(		exe,
			kwargs
	)

Returns an ImmutableRunner that will run the specified program.

Returns

an empty list

Note

This function does NOT search $PATH. That ensures the $PATH will be expanded on the compute node instead. Use produtil.fileop.find_exe() if you want to explicitly search the PATH before execution

Parameters

exe	The executable to run on compute nodes.
kwargs	Ignored.

Definition at line 92 of file lsf_cray_intel.py.

def produtil.mpi_impl.lsf_cray_intel.mpirunner2	(		arg,
			allranks = False,
			logger = None,
			kwargs
	)

Turns a produtil.mpiprog.MPIRanksBase tree into a produtil.prog.Runner.

Parameters

arg	a tree of produtil.mpiprog.MPIRanksBase objects
allranks	if True, and only one rank is requested by arg, then all MPI ranks will be used
logger	a logging.Logger for log messages
kwargs	passed to produtil.mpi_impl.mpi_impl_base.CMDFGen when mpiserial is in use.

Returns

a produtil.prog.Runner that will run the selected MPI program

def produtil.mpi_impl.lsf_cray_intel.openmp	(		arg,
			threads
	)

Adds OpenMP support to the provided object.

Parameters

arg	An produtil.prog.Runner or produtil.mpiprog.MPIRanksBase object tree
threads	the number of threads, or threads per rank, an integer

def produtil.mpi_impl.lsf_cray_intel.runsync

(

logger = None

)

Runs the "sync" command as an exe().
