Hi Team,
I am trying to run an application using MVAPICH2-2.0.
The application compiles without any error, but at runtime, aborts with
following error:
Fatal error in PMPI_Isend:Invalid tag, error stack:PMPI_Isend(149): MPI_Isend(buf=0x7f59b5124300, count=8, MPI_UNSIGNED_LONG,
dest=0, tag=1073741824, comm=0x84000001, request=0x132ae24) failed PMPI_Isend(98).:
Invalid tag, value is 1073741824
I contacted MVAPICH2 team for this issue:
