Hi Daniel, that looks like the problem I had with my intel build of openmpi. I could solve it by upgrading the Intel Compiler version to 12.1.2.273: % icc -v icc version 12.1.2 (gcc version 4.4.5 compatibility) % icc -V Intel(R) C Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 12.1 Build 20111128 Copyright (C) 1985-2011 Intel Corporation. All rights reserved. After a rebuild of the openmpi runtime, the crashes went away. I was using openmpi 1.5.3, but you could still have the same problem. Regards, Götz
