ParaStation MPI provides a parallel shell tool called
psh, which allows
to run commands on all or selected nodes of the cluster in
parallel. The output of the individual commands is presented in
a sophisticated manner, showing common parts and differences.
psh may also be used to copy files to all
nodes of the cluster in parallel.
This command is not intended to run interactive commands in parallel, but to run a single task in parallel on all or a bunch of nodes and prepare the output to be easily read by the user.
