Hi,
I build up a small linux cluster (red hat 9.0) configurated as follow:
pentium IV 2.8 Ghz 1Gb ram connected each other with
switch Hp procurve 2724 (giga)
I use namd2.5 ver. Linux-i686-TCP, other version does not work.
When i start my simulation on 2 processors, it works well. If I increase the
number of processors 4, 6, 8 etc. the program generates the following error
message:
Charmrun: error on request socket--
Socket closed before recv.
this message appear faster if i increase the number of processors
Could someone help me?
