I am not advocating that physics majors learn Fortran - since most physics majors will end up in research, their time may be better invested in learning C++ (or just sticking with Matlab/Octave/Python). What I would like to do in this article is explain why Fortran is still a useful language. The heavy use of Fortran by physicists often confounds computer scientists and other outsiders who tend to view Fortran as a historical anachronism. Coarrays started as an extension of Fortran 95 and were incorporated into Fortran 2008 standard. Modern Fortran also has a feature called ‘ coarrays‘ which puts parallelization features directly into the language.

So basically, if you want fast code that an run on many processors, you are limited to these two options. The popular Open MPI libraries for parallelizing code were developed for these two languages. In the field of high performance computing (HPC), of which large scale numerical simulation is a subset, there are only two languages in use today - C++ and “modern Fortran” (Fortran 90/95/03/08). SIESTA), large scale climate models, etc. Flash), large scale molecular dynamics, electronic structure calculation codes (cf. for things like the astrophysical modeling of stars and galaxies, hydrodynamics codes (cf. However, Fortran is still a dominant language for the large scale simulation of physical systems, ie. “I don’t know what the programming language of the year 2000 will look like, but I know it will be called FORTRAN.” – Charles Anthony Richard Hoare, circa 1982įortran is rarely used today in industry - one ranking ranks it behind 29 other languages.
