Dear All,
I configured gromacs 3.3.3 for parallel runs, using the precompiled packeges on
ubuntu server 8.04, with LAM program 7.1.2 ( alreay present in server verison).
I tried with d.villin benchmark but I detected an decrease of performance
increasing the node's number.
The obtained results for 1 node are:
(Mnbf/s) (GFlops) (ns/day) (hour/ns)
Performance: 6.686 1.437 8.471 2.833
The obtained results for 7 nodes are:
(Mnbf/s) (GFlops) (ns/day) (hour/ns)
Performance: 5.169 1.112 6.545 3.667
I have a cluster of 7 nodes (pentium 4 3.2 Ghz with RAM 2Gb) connected on
10/100 Mbps dual speed up hub.
I don't know if it is a configuration problem (because with precompiled
packages I couldn't use the configuration parameters described on web) or an
hardware problem due to hub.
Please can you help me?
Is possible to improve performance changing some other parameters or
configuration settings?
Thank you in advance
Best regards
Mario
