[mpich-discuss] mpi_barrier() failed

[王凯]

Hi!
I have two computer in the MPI program, and I use the function mpi_barrier(MPI_COMM_WORLD) to synchronize the two process on the two computer.
One of the process is running more slower than the other one because two different GPUs is on the two computer, and this means that one process has to wait for a long time(about several minutes). The error information is:
--PMPI_Barrier(425): MPI_Barrier(MPI_COMM_WORLD) failed
--MPIR_BARRIER_impl(331): Failure during collective
--gen_cnting_fail_handler(1738): connect failed-The semaphore timeout period has expired.
My MPI version is 1.3.2 p1-win-x86-64 and my OS is windows server 2008R2.
