[Wien] mpich2

[Laurence Marks]

Dear All,

Using WIen2k with mpich (or mvapich/openmpi) is not hard once one has
fought through Intel's compilation options.

I am wondering if anyone has any experience with mpich2 -- the daemon
version. It would be useful to share this. Some specific questions:
a) Is it best to start the daemons as root and leave them sitting, or
on a user basis?
b) Are they started by a pbs job, by a user script or what? Which is better?
c) Has anyone benchmarked mpich2 versus mpich (or other variants)?
