(Perhaps this doesn't quite fit in bug-bash, but help-bash doesn't seem
like the right spot, either.)
In case anyone here is interested in writing massively parallel bash
scripts, I hereby present MPI-Bash, a set of loadable builtins for
bash that let you use the Message Passing Interface (MPI) to
communicate across a cluster network. There's also support for the
Libcircle distributed-queueing system for easy task distribution.
Here's the MPI-Bash URL:

So far, I've used MPI-Bash to wrap the cp, tar, and xz commands into
parallel versions that run pretty fast on a parallel filesystem.
Enjoy,
