Polyhedron Fortran 2005 benchmarking (AMD64)

The following results were obtained with the Polyhedron 2005 Benchmark Suite on an AMD Athlon64 4800+ (dual core, 1MB L2 cache each, SSE, SSE2, SSE3), 4GB DDR400 CL2.5, SATA-II running openSUSE Factory in x86_64 mode.

The results have been obtained by averaging over three results (parameters: 200 0.1 3 3; since 2007-06-11: 300 0.5 5 10).

As only the gfortran trunk binaries changes daily, daily variations of the other compilers should not happen!

Run time

As of Fri, 13 Nov 2009 11:16:59 +0100

Color code: Dark green: Within 4% of the fastest; light green: within 7% of the fastest; light red slower by more than 20% than the fastest; dark red: by more than 50%. (In order not to cheat, gfortran[Prof] results are not for comparison of the fastest.)

GCC bug reports: PR31897. The crash (internal compiler error) of g95 and of gfortran 4.1 is a backend issue triggered with -ftree-vectorize.

Note: Using -mrecip gas_dyn is sped up by 30%, but aermod does a direct comparison of two floating point numbers which fails due to slightly differened results.
