General Notes
The system bus runs at 800 MHz Binaries were built on Windows Vista32 The following VS 2005 SP1 updates were applied: KB926601 and KB932232 OMP_NUM_THREADS set to number of cores KMP_AFFINITY set to physical,0 The start command with the /affinity switch was used to bind processes to cores
