Hi, Has anybody tries getting Prime95/mprime to work with huge pages? I recently hacked a program into allocating huge pages for a 1GB allocation, and the speedup was an amazing 20%... It's been quite a while since I read through the GIMPS source code, but IIRC it did complain quite a bit about TLB cache being a limiting factor, and huge pages would relieve that by quite a bit, so although I don't really believe in 20% (we don't do 1GB FFTs :-) ), it could be worth a try.
