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

Make Gauss-Seidel great again! – Dr. Jean-Christophe Loiseau

The art of unrolling.

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

Gauss-Seidel is faster than Jacobi. Or is it? – Dr. Jean-Christophe Loiseau

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

Portability of Fortran's 'do concurrent' on GPUs II

There continues to be growing interest in using standard language constructs for parallel and accelerated HPC computing, avoiding the need for (sometimes vendor-specific) external APIs. For...

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 !
Bilel Hadri@mnoukhiya18 Nov 2024
Full room for the 1st keynote talk by @thoefler on the AI for Science workshop #SC24. We are at the age of computing, traditional HPC simulations on today’s supercomputers is not enough for the low resolution. Need AI models to push the boundary.
