I haven't tried the lno-branch compiler. Lord knows, there aren't enough versions of GCC on my system already (12 at last count). I *am* looking forward to vectorization. According to the GCC docs, -ftree-loop-optimize is enabled at -O and higher. I'm not familiar with -fscalar-evolutions. -- Scott Robert Ladd Coyote Gulch Productions (http://www.coyotegulch.com) Software Invention for High-Performance Computing
