I recently wrote a program to test my new computer. I wanted to test the wattage range and cooling of the new processor so needed a program that would keep all the cores of the processor busy. The Core i7-950 is a 4 core processor with Hyper-Threading which means that there are a max of 8 threads. Since AMD provides server processors with up to 12 threads so the program has a maximum number threads of 32. I use the HWMonitor program to monitor temperatures and wattage if your processor supports it.
