The benchmark's source versions

The heavy importance of the compiler in number crunching application is the major cause for migration of the compilers' preprocessor, a critical technological component of the supercomputer microcosm of the eighties, to the mainstream of the RISC chip world, in the first half of the nineties. Thanks to these preprocessors, and to other beautifiers and F90 translators, the original source evolves into many derived versions available here:

Yet, ATT's f2c among other less-able softwares, allows one more version of the original source: this translation, from f77 to C, although crude but very solid and incredibly reliable, starts new comparisons with C compilers in numerical processing and shows that GNU's g77 might be a real alternative for fortran programming without a commercial fortran compiler.
