I am looking at the GCC 3.3.4 libstc++v3 tests and I'm trying to

the libstc++v3 tests each time.

Unless the machines are all identical, you cannot be sure that the
compilation would not proceed differently, leading to different
results.  If the machines are all identical, I'm not sure why you'd
want to do this.

What problem are you trying to solve?

I have often wanted to do what George describes.  We have
racks and racks and racks of identical machines, and I'd
like to run the tests in parallel on all of them,
to catch bugs that only happen rarely.  (e.g.,
which takes about 2000 cpu-minutes to show up).
