A list of rcmd modules currently distributed with pdsh follows. >> rsh Uses an internal, thread-safe implementation of BSD >> rcmd(3) to run commands using the standard rsh(1) protocol. >> ssh Uses a variant of popen(3) to run multiple copies >> of the ssh(1) command. mrsh This module uses the >> mrsh(1) protocol to execute jobs on remote hosts.

Remote nodes >> must be running mrshd(8) in order for the mrsh module to work. >> qsh Allows pdsh to execute MPI jobs over QsNet. >> Qshell propagates the current working directory, pdsh environment, >> and Elan capabilities to the remote process.
