Hi,

I don't know if this counts as a network, but I used MPICH 1.12 on
my PC(486-100/16 Mb)  to develop a parallelized version of 
an Euler-Code Solver (;-). Instead of logging onto other machines,
I logged into my own machine. All I had to do
was to get the TC/PIP stuff setup and give myself an regular account to be
able to use "rsh" (this command is used to start the programs).
Since I used to always login as root, "rsh" did not work until I gave
myself on regular account.
( Please no bashing on me here (:-))

This setup worked very well for me. It allowed me to use the same
source ( almost, since I could not find a standard cpu-time routine )
on my PC as well as on the Intel Paragon XP/S.
Getting the program running on the Paragon was a matter of just
recompiling with different compiler-settings. ( g77 <-> Intel F77 )


CU,

Ralph Paul
