As far as I could see from reading the mpirun script; yes, the files
will need to exist in identical paths on each "processor". Anyone
more clueful than me (=everybody? ;), feel free to correct me if
I'm wrong. :)

I would also like to comment on a few of the problems I've encountered
when trying out MPICH on my computer (SMP); Both the mpich-1.1.2.tar.gz
and the examples.tar.gz are FULL of hard-coded paths to various libs,
include-dirs etc. Why!?? It's very frustrating having to go through
a bunch of files, replacing "/home/lusk" (or whatever it was) with
e.g. "/usr/local". Even the mpireconfig tool gave up on me.

Also, quite a few of the sample-apps required various header files
that - for reasons unknown to me - were left out, resulting in a ton
of error messages. Easy to fix, but annoying nevertheless...

So, my question is; have I grabbed the wrong files, or are we poor
newbies supposed to go through this "baptism of fire"? ;)

Thanks,
