[gmx-users] strange problem with parallel mpirun

[Lubos Vrbka]

hi,
> What kind of system is this?
if you mean hardware & software then it's (mostly debian) linux cluster 
(2 proc nodes) , various processor types - from p3/800mhz to xeons/3.6ghz

if you mean the simulation, it's just water (six center from nada & van 
der eerden)

but why does it give problems for 5+ processors only? i probably might 
try to use it, however with mpich i have all the support from the guys 
that run this computer center. also, i want to build and run gromacs on 
myrinet - how is it with lam?

regards,
