[gmx-developers] parallel simulation crash on 6 processors

[servaas michielssens]

I tried to run a gromacs simulation (gromacs 3.3.1, MD, 18000 atoms) on 2 systems:

Intel(R) Pentium(R) CPU 2.40GHz with 100Mbit network
and
AMD Opteron(tm) Processor 250 with 1Gbit network
On both systems I had a crash when I tried to run with more then 5 processors. From 1-5 there was no problem.


kind regards,
