I've just read the paper and they look both useful and interesting to implement. Adam mentioned that GHC would need to be extended first, and I can't really judge how much work that would be. Can anyone chime in on how feasible that is? > I'm less familiar with the literature on concurrent hash tables. TBB's have > been a little bit underwhelming in performance. But it's definitely an > important structure. Ditto for priority queues. The data structures I mentioned were just my initial ideas, I'm open to any other suggestions. In my (limited) experience with parallel programming, queues and priority queues tend to come up quite a bit, but I'd be happy to get input from anyone with more experience regarding what would be useful/important. _______________________________________________ Haskell-Cafe mailing list [email protected] http://www.haskell.org/mailman/listinfo/haskell-cafe
