Dear Amberians:
We have a sun cluster system of sun fire x4150 server with a master node and
4 compute node and mpi for parallel process with Amber 10. When we run
sander.MPI we got the following error:
Fatal error in MPI_Allgather: Invalid communicator, error stack:
MPI_Allgather(865): MPI_Allgather(sbuf=0x2a955a5f30, scount=8415,
MPI_DOUBLE_PRECISION, rbuf=0x5d748f0, rcount=8415, MPI_DOUBLE_PRECISION,
comm=0x0) failed
MPI_Allgather(771): Invalid communicator[cli_0]: aborting job:
Fatal error in MPI_Allgather: Invalid communicator, error stack:
MPI_Allgather(865): MPI_Allgather(sbuf=0x2a955a5f30, scount=8415,
MPI_DOUBLE_PRECISION, rbuf=0x5d748f0, rcount=8415, MPI_DOUBLE_PRECISION,
comm=0x0) failed
MPI_Allgather(771): Invalid communicator
I am also attaching the input file and various other files with which the
error is associated.
Thank You,
Shubhra
