Now, with hyper-threading, you >_do_.... as >will most new machines from here on... Yes, the CCC thread(s) on hyper-threading are very interesting. As an outsider, I see this as a product of the general trend toward more complex microprocessors. Where can this lead? i.e. what is this new technology pointing toward? Maybe hyper-threading is a fledgling new techology which will blossom into something really spectacular. Maybe the ways chess engines are programmed today will have to change a lot? I also wonder what this new hyper-technology means to the "world of multiprocessor computers."
