# gfmpirun\_p4(1)

run Gfarm parallel programs with mpirun

## 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)](/gfreg/1.md).

## 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.
