Hello, Fernando,<br><br>the default MPI error handler would abort the process on an error. Since the call returns successfully a nonzero mpi_error might indicate memory corruption. It is hard to tell really without seeing the code. Could you isolate the problem into a small piece of code that you could post on the list?<br>

Hello Dmitri,<br><br>My intent is not to the rank 0 will send a message from itself. <br><br>I run these test over 1 machine and it simule several nodes (mpirun -np 4). The machine run over debian etch, gcc 4.1 and mpich 1.0.6.<br>
<br>I've noticed when run test is MPI_Recv return (No mpi error), but status.MPI_ERROR is different from zero. Can this happen?<br><br>thanks,<br><font color="#888888"><br>Fernando</font><div><div></div><div class="h5">

It seems that you call MPI_Recv on process with rank 0 to receive a message from itself. Is this what's intended?<br><br>
Error 22 would normally stay for "Invalid argument". This error would be posted by a bind call on a socket that is already bound.<br><br>Could you post more information and describe your configuration in more detail.<br>
<br>Hope this helps,<br> Dima<div><div></div><div><br><br><div class="gmail_quote">On Tue, Oct 6, 2009 at 11:01 PM, Fernando Saez <span dir="ltr"><<a href="mailto:saezfernando@gmail.com" target="_blank">saezfernando@gmail.com</a>></span> wrote:<br>

Dear MPICH discussion group<br><br>I am trying to run a MPI program, but I fail with the following error:<br><br>1: Fatal error in MPI_Recv: Other MPI error, error stack:<br>1: MPI_Recv(186)................: MPI_Recv(buf=0xbfdf70e8, count=52, MPI_DOUBLE, src=0, tag=0, MPI_COMM_WORLD, status=0xbfdf6f34) failed<br>
