Dear Absoft, Please fix the errors on your web page:
http://www.absoft.com/Absoft_Windows_Compiler.htm The comparison chart is not only misleading, it is a down right lie! The last column is labeled "GNU g77 gfortran". g77 and gfortran are completely different compilers! gfortran is a Fortran 95, and in fact, gfortran probably supports more Fortran 2003 and draft Fortran 2008 features than Absoft's product. Your chart clearly states that gfortran is not a 'Native f95 compiler". What does 'native' mean, here? The chart indicates that gfortran doesn't use SSE. Well, gfortran can use SSE if your processor has these features. You need to use the options -msse -msse2 -msse3 -mssse3 -msse4.1 -msse4.2 and -msse4 to get sse or one the -march= options. What to you mean by "top 10% performance" in your chart? gfortran performs as well as or better than Absoft's product on many of the Polyhedron Benchmarks. Your PDF file under the Linux Benchmark is quite misleading. You are comparing gfortran 4.1.2 (released on 2/17/07) against your product. Try comparing to gfortran 4.3.2 (the current release) or the upcoming gfortran 4.4.0 release. You do not include gfortran in the Windows benchmarch, and the MacOS X comparison uses 4.3.0. Wow, that's consistent! Your chart states that gfortran doesn't support Mil Std 1753. In fact, gfortran has supported Mil Std 1753 for a very long time. Please fix your chart. What do you mean by "Mixed Platform Licenses"? gfortran can be run on more architectures and operating systems than Absoft's product and you only need to understanding the GPL (an Open Source License, ie., it's free). Note there is a win64 version of gfortran provided by www.equation.com. Again, your chart is misleading. -- Steve
