Hi, I run my parallelized code which is similar to step-18 on HPC. When I run
it in multiple mpi processes on a single node. It can give me a good solution.
However, when I run it on multiple nodes of HPC and each node has one mpi
process, it reported an error as follows.
Are you saying that the same number of MPI processes works when you run
locally, but doesn't when run on a cluster? That doesn't make any sense --
nothing in the code depends on *where* these MPI processes run.
Are you running in debug mode in both cases?
