Hi,
Thanks for your response
No the program does not fail immediately it runs for a while and fails.
remember the same code runs just fine on other cluster...
Here I am also sending the output for laminfo

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
