Compile on Froggy cluster
Hi there,
I wanted to let you know that yade-mpi is now running on froggy cluster
(Grenoble) based on the NIX package by William (thanks!).
An alternative method without using NIX has been also found by Deepak.
It may be more transparent than NIX in terms of compilation, so also
good to have (Deepak, could you please forward your explanations here?).
Here is a quick walkthrough (one-liner at the end), please try it and
let us know if you find problems, so we can update it before moving it
to ciment's wiki.
Cheers
Bruno
