PROGRAM:

NAME


likwid-mpirun - A tool to start and monitor MPI applications with LIKWID

SYNOPSIS


likwid-memsweeper [-hd] [-hostfile filename] [-nperdomain number_of_processes_in_domain]
[-pin expression] [-omp expression] [-mpi expression] [--]

DESCRIPTION


likwid-mpirun is a command line application that wraps the vendor-specific mpirun tool and
adds calls to likwid-perfctr(1) to the execution string. The user-given application is
ran, measured and the results returned to the staring node.

OPTIONS


-h prints a help message to standard output, then exits.

-d prints debug messages to standard output.

-hostfile filename
specifies the nodes to schedule the MPI processes on

-nperdomain number_of_processes_in_domain
specifies the processes per affinity domain (see likwid-pin for info about affinity
domains)

-pin expression
specifies the pinning for hybrid execution (see likwid-pin for info about affinity
domains)

-omp expression
enables hybrid setup. Can only be used in combination with -pin. The only possible
value is: intel

-mpi expression
specifies the MPI implementation that should be used by the wrapper. Possible
values are intelmpi, openmpi and mvapich2

-- stops parsing arguments for likwid-mpirun, in order to set options for underlying
MPI implementation after --.

EXAMPLE


1. For standard application:

likwid-mpirun -np 32 ./myApp

Will run 32 MPI processes, each host is filled with as much processes as written in ppn

2. With pinning:

likwid-mpirun -np 32 -nperdomain S:2 ./myApp

Will start 32 MPI processes with 2 processes per socket.

3. For hybrid runs:

likwid-mpirun -np 32 -pin M0:0-3_M1:0-3 ./myApp

Will start 32 MPI processes with 2 processes per node. Threads of the first process are
pinned to the cores 0-3 in NUMA domain 0 (M0). The OpenMP threads of the second process
are pinned to the first four cores in NUMA domain 1 (M1)
