I have a 4 node cluster(dont snicker :) ) and Im trying to do some
benchmarking with HPL. I want to test 2 of the nodes with 1Gb of
ram each. I calculated the maximum problem size that can fit in 2Gb
and still allow for memory for the operating system. That came out to
be around 14500x14500. When I run that size of a test it always fails.
The largest problem that I can test and not have it fail on me is
What is the reason behind this? Im confused on what is going on here.
Thanks for any help.
