[gmx-users] REMD and swaplist

I am trying the code of REMD in gromacs3.1.4 designed by Luca and Walter.
I have tried it in an *old* cluster and it runs very nice!!
But when I run it on a new cluster under scali, the simulation gets
*frozen* after ~ 5 minutes of being running.
It stops at the point where (to my understanding) the communication
between nodes takes place:
***** Master says: this is the IDTswaplist
(the simulation is reported to be running but does not do anything else
after this point)
What is more strange is that the simulation has already had communication
between nodes (i.e. swaping has taken place before).
Has anybody faced this problem? I am not familiar with mpi programming but
I wonder whether this is a problem of the code or a problem of scali (of
course the system manager of my group claims that scali is working
Standard parallel jobs of gromacs 3.2.1 run on that new cluster (with
scali) without any problem!
Does anybody have any suggestion for this problem??
thanks in advance!,
