This is also a memory The -x parameter for icc doesn't always helps. It depends on the application. You may try to use some variations of -xiMKW (-xi, -xiM, -xM, -xiMK, ...). -parallel and -mt may be of use too (and the obvious parameters like -ipo, -tpp7, -O too). > intesive calculation so I am planning to check out which is > the bottle neck (and to help this I happen to have i845, i850, > i845G, and also MPX760 Athlones :-) ) This sounds like nice toys... icc also produces fast code for the Athlon (-tpp6).
