Hi 


I made a mistake. I compiled my software with one version of MPICH2 and i was trying to run it with other version. 


Problem Solved

I'm using mpich2 1.1 in rocks linux. 


Recently we added to myrinet boards to our cluster, before that we didn't had any problems and thread level provided by mpich2 was MPI_THREAD_MULTIPLE. 


If i try to run the job in the machine that has no myrinet ( 4 cores ) it runs without problem, although the thread level is still MPI_THREAD_SERIALIZED. 




Thanks

Hi, 
Are you using MPICH2 on windows (If so, did you try running your job with the multithreaded sock channel or the nemesis channel, eg: mpiexec -n 2 -channel mt my_multithreaded_sw.exe )? 

Regards, 
Jayesh

Hi 


I'm trying to run a mpi multithreaded software, but i'm getting this error on MPI_Recv in one of the threads: 


"Fatal error in MPI_Recv: Error message texts are not available" 


Anyone knows a possible cause to this problem? 


Could it be becouse mpich2 just provides thread level MPI_THREAD_SERIALIZED?
