Hello all,
After I failed to run REMD using 32 replicas with amber8 as posted a few days ago,
I tried the same REMD job with amber9.
The parallel version of amber9 was installed without error on Intel Xeon cluster,
and the MPI version of sander with no replica exchange did the job without problem.
But a number of attempts to run the REMD job gave the error messages such as below.
.....
0 - MPI_COMM_RANK : Null communicator
[0] Aborting program !

1 - MPI_COMM_RANK : Null communicator

Please let me know how to fix this problem.
Thanks a lot.
