Dear Mvapich,
Our code has poor loadbalance, in the final stage of the run, only one
mpi process will continue to performance calculation, while others wait at
mpi_barrier. We have encountered problem that run fail, when the wait is
too long? do you have any advice on how to fix this problem?
Thank you very much.
