Fortran Compiler Comparisons 2016-2017

Abstract

Which is the best Fortran compiler? We're often asked that question, but there is no single answer. All compilers have strong and weak points, and your choice should depend on finding the best match between your requirements and a compiler's strengths. In professional environments, it probably makes sense to make use of two or more compilers, with different strengths – e.g. one for the best run-time performance, and another for superior bug-hunting capabilities. Using more than one compiler also make it less likely that you will become over-dependent on details of a single vendor's implementation. To help our customers make informed decisions, we have compiled a series of charts comparing the main contenders. The version numbers of the compilers used in these comparisons are listed in the Benchmark Tables 2.1 Compare Windows Compilers 2.1.1 Language – What extensions to standard Fortran do the compilers support? Here is the first table.
