![]() ![]() ![]() Despite the fact that this is the GCC fortran compiler! I would have expected the compilers to all cluster near 1 for these benchmarks, with NONE outperforming C and some underperforming by a factor of few depending primarily on how dynamic the structure was.įortran is average in the sense that it is the extreme outlier, that is the ONLY one of these languages to significantly outperform C on any of these computational tasks, and only underperforms significantly on the one obvious one. Hmm: the benchmarks say that there is a four order of magnitude variation in the performance of compilers for widely used and popular languages for simple core computational tasks.ĭespite the fact that commodity computing is now a near monoculture and most of these compilers as a first approximation cross-compile into something like C object code and run under *nix kernel running on a very predictable CPU The benchmark by design does not show that Fortran is superior. I will restrain myself and not continue bashing Fortran for the lack of good libraries and stuff, but your claim is simply wrong. Which tells you that Fortran does not really excel, but is about average as one would expect intuitively. at the Matlab values, those benchmarks that measure real performance of the underlying system, or contain loops that can be easily vectorized (pi_sum, mat_mult) are about the C level. Not surprisingly, it gives about the worst speeds in all scripting languages. It has no further validity.Īs an example, the Fibonacci benchmark is implemented recursively, which is something you would never do in a scripting language because function calls are really expensive there. Second, the benchmark tests the performance of low-level features to show that Julia performs well here, in contrast to scripting languages. And since the Fibonacci implementation is purely recursive (and, honestly, pretty bad), it might well be that the compiler just makes the smarter decision about which path to follow by default here. OK…still want to learn Fortran?… you must have some good reasons then -)įor me, it was mainly because I was looking into the source code of Code_Aster, and I realised that so much of it is written in FORTRAN….Actually, the benchmark says that Fortran is merely average.Īll the numbers, with the exception of the Fibonacci series cluster around the C values. I’ll have also some videos about Python too on the blog soon… -) If this is your first language and you are just getting into programmation and you want to make some simple programs I don’t recommend you to go into Fortran so just leave this video and instead try to learn Python So why would you like to study Fortran actually? Let me explain first why I’m doing that because Fortran is a very old language… I decided to make a few videos about Fortran and that’s why I’m talking about that right now on the blog Just search “compile FORTRAN on windows” and you will find quite a few -) 1- Why studying Fortran? There are some solutions for windows and mac You don’t need to have Ubuntu though to compile fortran of course! ![]() – How to write a quick Hello World ScriptĪll the tutorials will be on Ubuntu 16.04 that you can download and install freely on a second partition or a virtual machine if you like: In this tutorial, I’ll introduce you to the most basic things you should know about FORTRAN: ![]()
