Debian/Ubuntu/Redhat which is better for heavy duty computations?
I was wondering if anybody knows if there exist benchmarks done to
compare the performance for floating point computations (for example
lapack) on opteron with the Debian, Ubuntu and Redhat AMD 64 ports.
My research group recently got a couple of new multi-proc opteron
machines and even though they shipped with redhat enterprise, being a
fan of debian I was wondering if Debian AMD64 or Ubuntu might not be
better? Has anybody compared performance systematically?
