pssh [ -? ]
pssh runs a command on a remote node. It is similar to the ssh command, except that the ParaStation MPI daemon is used to start the remote command.
-e,
--exports=
envlist
Export the environment variables
envlist to the remote command.
Envlist may be a single
variable name or a colon separated list of names.
-h,
--host=
node
Run command on node node.
-l,
--login=
name
Login as user name.
Only root may login as a different user on the node.
-n,
--node=
node-id
Run command on node with ID
node-id.
-r,
--rusage
Report resource usage upon exit.
-v
Be more verbose.
-V
Print version and exit.
-?,
--help

--usage
Show a usage message.
The pssh command runs a shell or a command
command providing arguments
args as an admin-task on a remote
node.
The local user must be within the adminuser
list of the ParaStation MPI daemon or must be a member of the
admingroup list.
Refer to
psiadmin(8) and ParaStation MPI User's Guide
for details how to configure
adminusers or
admingroups.
Only root may use the -l option to login as a
different user.
The destination host may be either specified using the hosts
ParaStation MPI node ID (option -n) or using the
hosts name (option -h).
The admin-task run by pssh will not be counted for the ParaStation MPI process placement and will not be started obeying the placement rules enforced by ParaStation MPI.
To run a serial task using the ParaStation MPI process placement rules, use psmstart(8). To run a command in parallel on multiple nodes, use psh(8). To run a parallel job, use mpiexec(8).
