    Parallelism can be smooth as Cilk? (pronounced "Silk")

    If you've visited cilk.com today, you see that the Cilk engineering team has joined Intel. I was surprised how fast I've gotten questions from a note on the Cilk web site on a Friday afternoon - it happened only minutes after the posting!  I've been a follower of Cilk technology for some time now - and it is exciting to have the opportunity to work with the team that is joining us! Working together we will result in even more options for parallel programming!

    internal threshold was exceeded

    In very large, complex functions, loops preceded by OpenMP directives may not be threaded. Compiler may emit the warning remark: "An internal threshold was exceeded: loops may not be vectorized or parallelized. Try to reduce routine size."
