Overview

Pdsh is a high-performance, parallel remote shell utility. It uses a sliding window of threads to execute remote commands, conserving socket resources while allowing some connections to timeout if needed. It was originally written as a replacement for IBM's DSH on clusters at LLNL.

The core functionality of pdsh is supplemented by many available dynamically loadable modules. The modules may implement a new connection protocol, target host filtering (e.g. removing hosts that are "down" from the target host list) and/or other host selection options (e.g. -a selects all hosts from a config file).

The pdsh distribution also contains a parallel remote copy utility (pdcp - copy from local host to a group of remote hosts in parallel), reverse parallel remote copy (rpdcp, copy from a group of hosts to localhost in parallel), and a script dshbak for formatting and demultiplexing pdsh output.
