Hi,
We would appreciate if you could provide more details of the condition
under which the program is failing. Does it fail immediately after
starting or does it fail after running for a while ?
You could also check if the memory management for the huge matrix is being
done properly.
Output of laminfo will also give us an idea about the environment.
Thanks,
Nihar
