Subject: Re: [OMPI users] Segmentation fault when Send/Recv on heterogeneouscluster (32/64 bit machines) (Timur Magomedov)

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
