we're lucky here ;-) http://gcc.gnu.org/benchmarks/ has a link to http://cp2k.berlios.de/gfortran/ the code discussed (in particular the above collocate_fast_2.f90) is (in a slightly older but equivalent variant, see ftp://ftp.berlios.de/pub/cp2k/gfortran/gcc_bench.tgz) a significant part of the bench01 benchmark. Getting the same performance as ifort on this kernel would speedup this benchmark with ~ 10% which would be highly significant. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37150
