True true. I didn't mean 2 separate CPU's ala Power4. I meant 2 distinct execution units -- also misleading: all superscalar processors have multiple execution units. Anyway I think we're all agreed on this -- it's hyperthreading, therefore 2 threads (not instructions, but threads) can run in parallel, so it shows up as 2 CPU's. --- Orlando Andico <[EMAIL PROTECTED]> Mosaic Communications, Inc. _ Philippine Linux Users Group.
