I don't know if people realise this, but only certain tasks are suitable for parellelism. Specifically, tasks that can be split into completely seperate units with no data sharing between threads. Once you have data shared by several threads, then you have thread synchonisation issues and you are in store for some *pain* Big Grin | :-D
