<br>
I'm using mpich2 1.1 in rocks linux.<br>
<br>
<br>
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.<br>
<br>
<br>
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.<br>
<br>
<br>
<br>
<br>
Thanks<br>

Hi,<br>
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 )?<br>
<br>
Regards,<br>

<br>
Hi<br>
<br>
<br>
I'm trying to run a mpi multithreaded software, but i'm getting this error on MPI_Recv in one of the threads:<br>
<br>
<br>
"Fatal error in MPI_Recv: Error message texts are not available"<br>
<br>
<br>
Anyone knows a possible cause to this problem?<br>
<br>
<br>
Could it be becouse mpich2 just provides thread level MPI_THREAD_SERIALIZED?<br>
<br>
<br>
<br>
