NAME

gfmpirun_p4 - run Gfarm parallel programs with mpirun

SYNOPSIS

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.
