New post: quantifying Gauss-Seidel's loop-carried dependency with OSACA, and a loop-unrolling fix that cuts it from 12 to 2 cycles/element. Three compiler experiments included to isolate the effect from vectorization. 👉 tinyurl.com/3h79t8fn

It's been a while ! I've just publish a new post: 𝐆𝐚𝐮𝐬𝐬-𝐒𝐞𝐢𝐝𝐞𝐥 𝐢𝐬 𝐟𝐚𝐬𝐭𝐞𝐫 𝐭𝐡𝐚𝐧 𝐉𝐚𝐜𝐨𝐛𝐢. 𝐎𝐫 𝐢𝐬 𝐢𝐭? While keeping a high level p.o.v., I try to explain why Jacobi can be faster than Gauss-Seidel despite what the math says. tinyurl.com/yme7dahk

The Oregon Trail in the browser – FORTRAN 77 to WebAssembly with LFortran, by @minhqdao .

Want to run your @fortranlang #Fortran code on GPUs but don't want to add external APIs or directives? Check out our new paper on using Fortran's "do concurrent" to run on NVIDIA, AMD, and Intel GPUs! arxiv.org/abs/2608.20586 Adding @OpenMP_ARB data movement directives can help with efficiency (on Intel GPUs) and for some GPUs are required (AMD consumer GPUs), but for many cases, "Fortran-only" works great - even across multiple multi-GPU nodes! @FortranWiki @fortrantip @nvidiadeveloper @AMDGPU_ @AMDServer @IntelDevTools @inteldevs

`fpm 0.13.0` was recently released: check it out and let us know your experience with customized features and profiles! @fortranlang fortran-lang.discourse.group…

did? DOES! @fortranlang @lfortranorg #Fortran @Fortran All our software projects are written in Fortran 2023 - check one out! github.com/predsci/hipft

There's still time to submit an abstract to FortranCon 2025. What are you waiting for? events.fortrancon.org/event/… Final submission deadline is September 12.

"Some reflections about stdlib, where it stands and what it could become" by @loiseau_jc: fortran-lang.discourse.group…

Advent of Code in @fortranlang?! - And using `pixi` to set up the @condaproject environments! Very cool @degenerateconic github.com/jacobwilliams/AoC…

LFortran supports all intrinsic functions. Great job by @HarshitaK1107 , Parth, @Pranavchiku and the rest of the team! lfortran.org/blog/2024/11/lf…

SC24 HPC creates! @thoefler is praising Fortran @fortranlang performance on a production code at the AI workshop for science 🤩! Fortran is in blue, performance achieved not only on a CPU, but also on the GPU. Long live to Fortran !

Fortran (@fortranlang) is now #8 at TIOBE Index and continues rising. With new compilers maturing quickly, Fortran will become a very nice language for numerical computing. tiobe.com/tiobe-index/

#Fortran is #8 in the Nov 2024 #TIOBE index. The highest it is has ever been! @fortranlang tiobe.com/tiobe-index/

🚨New post: "Creating a Conda package from Fortran using fpm and rattler-build" 🚨 In this post, I explore how modern tooling like fpm and rattler-build can dramatically streamline creating Conda packages from Fortran code. samharrison.science/posts/co… @prefix_dev @fortranlang

hpcwire.com/2024-hpcwire-rea… @predsci is nominated for the "Best Use of HPC in Physical Sciences" for our 3-week continually running model of the solar corona to predict the 2024 total solar eclipse (predsci.com/eclipse2024). The codes needed for this simulation used @fortranlang standard parallelism, @OpenACCorg, and @OpenMP_ARB on @NVIDIAHPCDev GPUs, as well as MPI over hundreds of CPU compute nodes at @NASA_NAS. We invite you to take a look and vote!
