I've tried on my home Ubuntu 10.04, 64 bit version. It crashes with number of ranks 5-7, 9 and greater. I simply downloaded 1.4.3 version ( http://www.open-mpi.org/software/ompi/v1.4/downloads/openmpi-1.4.3.tar.gz):
- configure --prefix=`pwd`/install && make install - cd ~/projects/gather - ~/projects/distribs/openmpi-1.4.3/install/bin/mpicc -o gather ./gather.c - ~/projects/distribs/openmpi-1.4.3/install/bin/mpirun -n 9 ./gather - crash! -Andrew On Wed, May 25, 2011 at 10:48 PM, Andrew Senin <andrew.se...@itseez.com>wrote: > Not exactly.
