Mike: I've actually wasted money on the Intel compiler. Compared to MSC V6.0, the code generated by the Intel compiler was much larger, much slower, and _gave the wrong answers_. I used to believe in SPEC, but owning a copy of the Intel compiler changed my tune on that... We invested in Intel's compiler (VTune and all) about a year ago. Our code is very floating point heavy (quantum chemical simulations) and the SPECfp scores convinced us to give the Intel compiler a try. The results were much the same as you experienced. I couldn't even get the binaries to run, but our local REAL programmer (most of us are just physicists, with varying degrees of programming skill) did mange to produce a working binary. It was, however, significantly slower (the results were accurate enough, though). -fyo
