Hi, I downloaded the nightly trunk snapshot openmpi-1.7a1r23032. I recompiled openmpi and my test code, and put back the btl_tcp_eager_limit to default. The bug seems to be fixed. I don't have the segfault anymore even with big array (up to 685MB). Thanks to all the developpers.
There is a ticket on the bug trac about this problem that may need to be updated : https://svn.open-mpi.org/trac/ompi/ticket/2336 Regards, TMHieu On Mon, Apr 26, 2010 at 5:08 PM, <users-requ...@open-mpi.org> wrote: > > > Message: 9 > Date: Mon, 26 Apr 2010 13:19:38 +0400 > From: Timur Magomedov <timur.magome...@developonbox.ru> > Subject: Re: [OMPI users] Segmentation fault when Send/Recv on > heterogeneouscluster (32/64 bit machines) > To: Open MPI Users <us...@open-mpi.org> > Message-ID: <1272273578.2131.3.camel@magomedov-desktop> > Content-Type: text/plain; charset="UTF-8" > > Hello, > You can get nightly trunk snapshot from here > http://www.open-mpi.org/nightly/trunk/ > You can grab openmpi-1.7a1r23032 and test it.
