[mvapich-discuss] Application aborts at runtime.

[Hari Subramoni]

Hello Chaitra,

>From the error, it looks like the value of tag you're passing to MPI_Isend
is incorrect, possibly its < 0 or > INT_MAX (as defined on your system).
However, without more information on how you configured the MPI library
(output of mpiname -a), some more details of the application, it will be
hard to give an exact answer.

Regards,
Hari.
