Dear NAMD users,

I compiled NAMD using openmpi for 32-bit and 64-bit machines separately
(keeping them on individual machines with same names) and now when I would
like to run both executables simultaneously in parallel mode, it gives me
following error:

user_at_studpcxx:~$ mpirun -hostfile machines namd namd.conf

Charm++> Running on MPI version: 2.1 multi-thread support: MPI_THREAD_SINGLE
(max supported: MPI_THREAD_SINGLE)
Charm++> cpu topology info is being gathered.
Charm++> 2 unique compute nodes detected.

MPI_ABORT was invoked on rank 3 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

--------------------------------------------------------------------------
mpirun has exited due to process rank 2 with PID 16227 on
node sibar exiting without calling "finalize". This may
have caused other processes in the application to be
terminated by signals sent by mpirun (as reported here).

Has anybody tried to work with such mixed environment of 32-bit & 64-bit
machines..

Look forward to hear about the solution..

Thanking you,
Sincerely,
Yogesh
