Hi,
I have used POSIX threads in my parallel program,One of these threads contains
MPI_Send calls.
Some times this program shows undefined behaviour,some times it runs very well.
To have a stable program,I think that i should have to use
1- MPI_Thread calls instead of POSIX threads
2- a mutex lock for access to LAM,by any mpi call
Please guide me is it right or mutex lock will be sufficient with POSIX thread???
waiting anxiously for reply or answer.
regards
Ahmed irshad
