If your thread fills the array linearly, you could maintain a variable shared by those threads that say the last cell computed, and have the read thread check that before reading. I think this wouldn't create too much overhead, although it seems like there must be something cleverer somewhere. -- Felipe. _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
