Note also that unless you are on a 64bit architecture an individual
process in linux can't malloc more than 3GB of ram. If you have more than
4GB of ram on a intel32 bit architecture you're going to take an order of
3%-6% performance hit due to page flipping. all if this is academic if you
a sparc64,alpha, opteron, ppc64 or itanium but you may not.
