[mpich-discuss] Fatal error in MPI_Test: Invalid MPI_Request

[Samir Khanal]

Hi All
I tried and did the following.

[skhanal at comet ~]$ mpicxx -L /home/skhanal/bgtw/lib -lbgtw bgtwRingTest.cpp -o Ring
[skhanal at comet ~]$ mpiexec -n 4 ./Ring
Fatal error in MPI_Test: Invalid MPI_Request, error stack:
MPI_Test(152): MPI_Test(request=0x1f820388, flag=0x7fffb8236134, status=0x7fffb82360a0) failed
MPI_Test(75).: Invalid MPI_Requestrank 0 in job 35  comet.cs.bgsu.edu_35155   caused collective abort of all ranks
  exit status of rank 0: killed by signal 9

What does this mean?
Samir

Ps: I am using mpich2 1.0.8
