ORIGIN

pdsh/pdcp was originally a rewrite of IBM dsh(1) by Jim Garlick <garlick@llnl.gov> on LLNL’s ASCI

Blue-Paciﬁc IBM SP system. It is now also used on Linux clusters at LLNL.

LIMITATIONS

When using ssh for remote execution, stderr of ssh to be folded in with that of the remote command.

When invoked by pdcp, it is not possible for ssh to prompt for conﬁrmation if a host key changes, prompt

for passwords if RSA keys are not conﬁgured properly, etc.. Finally, the connect timeout is only adju-

stable with ssh when the underlying ssh implementation supports it, and pdsh has been built to use the

correct option.
