The established classification would be >upset on dual core machines. Fritz and Hiarcs are not multiprocessing capable. Only the Deep versions are. Hiarcs doesn't have a Deep version. Old Shredder versions were, essentially, both single and dual versions at the same time, but Stefan stopped doing this in Shredder 9. So, Shredder 8 is multiprocessor capable, but Shredder 9 is not, you need Deep Shredder 9 instead. -- GCP
