Will the suite make for faster binaries? That i could not find a definite answer for on phoronix.


I've been maintaining the LAPACK build and test infrastructure for ~ 6mo now and we've seen great performance numbers out of the PathScale compilers. Typical runtimes for the LAPACK test suite running 4 tests in parallel for 98 tests (this is on a 2 year old quad core xeon):

GNU Fortran : 1.5 min.
Intel Fortran : 0.7 min.
PGI Fortran : 0.7 min.
PathScale Fortran : 0.4 min.

I was blown away by it myself and almost didn't beleive it. I've seen comparable results with other C++ code bases. There are many contributing factors to the performance of your code (often HPC code will depend heavily on an optimized math library) and everybody's codebase and workload is different, but speaking from experience, for math intensive code the PathScale compiler is really top notch.
