[mpich-discuss] Application aborts at runtime

[Chaitra Kumar]

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:
http://mailman.cse.ohio-state.edu/pipermail/mvapich-discuss/2015-June/005623.html

They suggested me to contact MPICH team, as the issue is coming from higher
level MPICH code.

Can you please help me in resolving this.

Regards,
Chaitra
