NAME
gfmpirun_p4 - run Gfarm parallel programs with mpirunSYNOPSIS
gfmpirun_p4 [ options ] command args ...
DESCRIPTION
gfmpirun_p4 executes a parallel command on filesystem nodes with mpirun provided by MPICH/p4, which is determined by the -G option, the -H option, or the -N option.
-G, -H, and -N options are exclusive. When none of -G, -H, and -N options are not specified, gfmpirun_p4 schedules filesystem nodes by the file-affinity scheduling using the first existent Gfarm file in the argument list args.
Command can be specified by a gfarm-URL that is registered using gfreg(1).
OPTIONS
- -G gfarm-URL
- specifies a Gfarm file gfarm-URL for file-affinity scheduling.
- -H hostfile
- specifies a hostfile that lists filesystem nodes.
if ``-'' is specified, standard input is used to read the host list.
- -N np
- specifies the number of nodes np, which are selected by the increasing order of load average.
BUGS
gfmpirun_p4 can only work with the MPICH/p4.
