2. Project Summary
2.1 Project Description
Parallel command execution for clusters
4. Technical Description:
Pdsh is a high-performance, parallel remote shell utility. It has
built-in, thread-safe clients for Berkeley and Kerberos V4 rsh and can call SSH
externally (though with reduced performance). 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.
Pdsh is a variant of the rsh(1) command. Unlike rsh(1), which runs
commands on a single remote host, pdsh can run multiple remote commands in
parallel. pdsh uses a "sliding window" (or fanout) of threads to conserve
resources on the the initiating host while allowing some connections to time
out.
5. Interfaces
The binary file "pdsh" contains following interface.
