Hi,
Using opemi 2.1, the following code resulted in the core dump, although
only a simple error msg was expected. Any idea what is wrong? It seemed
related the errhandler somewhere.
D.G.
*** An error occurred in MPI_Reduce
*** reported by process [3645440001,0]
*** on communicator MPI_COMM_WORLD
***
*MPI_ERR_COUNT: invalid count argument* *** MPI_ERRORS_ARE_FATAL (processes
in this communicator will now abort,
*** and potentially your MPI job)
