Hey all, This is actually a 2 part interest inquiry: 1. I think there could be some usefulness in parallel versions of the algorithm functions, like for_each and find and unique_copy. 2. In the couple days of r&d I have come up with a class named parallel_task_master which runs a thread function many times over and manages them so you keep your thread counts low and working as hard as possible. So if you have a quad-core cpu it can be specified so you never go over a 4 thread limit. It's also setup so you can keep adding tasks recursively and it will keep the thread count fixed and never deadlock. Because the tasks in parallel_task_master run relatively in order, I think some sort of queue could be made to parallelize functions that needed to return output in a serial form. So it could be used to decode video stream packets for example. This parallel_task_master in itself may have some value alone, but it was written to assist in creating parallel version of the functions in <algorithm>. Some of them are not so parallelizable, some are embarrassingly so. -Clint Levijoki
