Ax=b for big A's

Postby bms » Wed Jun 11, 2008 2:17 pm

Hi, I'm using the example scaex.f in order to solve Ax=b. Actually, I
implemented the program so I can use the A&b that I'm interested in.

Question: could I get some advice as to how chose the 'memory' parameters
in scaex.f so I can do big A's?

So far, I've been able to do A's of N=22,048. When I go above this, the
program doesn't run. For instance, the message for N=25,536 is:

"Unable to perform test: need TOTMEM of at least -1685545584 "


I'm running on a Xeon-Quad cluster with 2GB of ram on each node.

Thanks for your help
