I encountered this problem using openmpi-1.2.5,
on a Opteron cluster with Myrinet-mx. I tried for
compilation of Global Arrays different compilers
(gfortran, intel, pathscale), the result is the same.
As I mentioned in the previous message GA itself works
fine, but the application which uses it doesn't work
correctly if it runs on several nodes. If it runs on
one node with several cores everything is fine. So I
thought that the problem might be in this additional
Should I try to use the latest 1.3 version of openmpi?
