[gmx-users] Mpi version of GROMACS - Doubt about its performance

[Alexandre Suman de Araujo]

Hi GMXer

I have a 4 nodes beowulf cluster and I installed de MPI version of 
GROMACS in it. To make a test I performed the same simulation in the 4 
nodes and after in only one node.
The  total time of simulation using the 4 nodes was only 10% faster than 
using only 1 node. This is correct???? Or somebody has a better performance?
The ethernet interface between the node is a 100Mb/s one... I think this 
is enough... or not???
Waiting coments.

Best Regards.
