   Instead they got a 3x code speedup over the Fortran code!

   At the SC19, the International Conference for Supercomputing in 2019, one of the Julia creators Alan Edelman recounts how a group at the Massachusetts Institute of Technology (MIT) rewrote part of their Fortran climate model into Julia. They determined ahead of time that they would tolerate a 3x slowdown of their code. That was an acceptable tradeoff to get access to a high-level language with higher productivity in their view. Instead they got a 3x speed boost by going over to Julia.

   Couldn't they have just coded in STATAh?

   Should I learn to code in julia

   If you have to ask, the answer is obviously "no".

   The "MIT Climate Model" is not a full climate model, just a dynamical core (with simplified physics) for the atmosphere and ocean. It's never created for operational uses of predicting climate. Instead, it's configured for academic purposes of understanding some specific dynamical processes, in an idealized setting.

   That's irrelevant to the claim that it ran faster in Julia than in Fortran, Beavis.

    I learnt on twitter that Stata is the only game in town.

    This just means the original Fortran code was inefficient and the inefficiency was somehow fixed when they rewrote the thing in Julia.

    Julia outperforms Fortran on some common code patterns.

    If they had rewritten the code in Fortran but used modern syntax for parallel computing, it would likewise have fixed the problem.

    If you're going through the grind of completely rewriting your code for CUDA anyways, why do it in a 50-yr old language?
