Thanks for the warning. I remember having to avoid rand() a decade ago because the implementation sucked for some old Unix. (HP-UX 8? I forget) I'd assumed that was a long-forgotten problem, but my own code uses random()/srandom() thanks to that experience. Any idea whether random() has the same problem on OS X? --- Roy ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
