Dear Rizwan,
Are you sure you have 64 GB of RAM per core, and not per node? 64GB per
node would be much more typical?
Additionally 16 cores per node sounds more likely than 16 processors per
node.
Assuming it should be 64 GB per node, one comment on your input - you've
set MAX_MEMORY to 5000, but this is the memory available
per core, not per node. It's likely you have only 4096 MB available per
core, and you do not want all of
this memory assigned to the HF routines as the rest of the code will need
some memory.
Check your computer's specs and check if this is a reasonable value for
this first.
Best regards,
Conrad
