pdsh

Efficient rsh-like utility, for using hosts in parallel

Efficient rsh-like utility, for using hosts in parallel
from version 2.29-1

Description

Pdsh is a high-performance, parallel remote shell utility, similar to dsh. It has built-in, thread-safe clients for rsh. Pdsh uses a "sliding window" parallel algorithm to conserve socket resources on the initiating node and to allow progress to continue while timeouts occur on some connections.

It makes all parallel connections from one client machine, and attempts to keep 32 (default, can be changed on command line) connections to remote machines at any given time. It can run single commands or as an interactive shell.
