[gmx-users] Replica Exchange problem in gmx-4.5 beta3

[Changwon Yang]

Hello!
I'm doing a simple REMD test with 4 replicas.
Time step : 2 fs
Exchange : every 500fs

md_0.tpr md_1.tpr md_2.tpr md_3.tpr 

mpiexec(or mpirun) -np 4 mdrun_mpi_d -deffnm md_ -multi 4 -replex 200
 I got a error message.

##error##
1000000 steps,   2000.0 ps.
step 600 rank 3 in job 10  localhost.localdomain_50305   caused collective abort of all ranks
  exit status of rank 3: killed by signal 11 
rank 2 in job 10  localhost.localdomain_50305   caused collective abort of all ranks
  exit status of rank 2: killed by signal 11 

Using gmx4.0.7 , It works fine.
Is this bug in gmx-4.5 beta ?
In log files, no error message were found.
gmx-4.5 beta3 was compiled with icc 11.0
and mpich2-1.2.1p1.
