The rantings of a stubborn GPU programmer

A Fortran programmer documented using LLMs and agentic workflows to write GPU-accelerated Fortran code, with posts on software architecture, OpenMP target offloading, and standard parallelism. The programmer plans to share their AI-assisted coding setup, while another user announced upcoming results on NVIDIA, AMD, and Intel GPUs.

jorgeg https://fortran-lang.discourse.group/u/jorgeg 1 I have kept a “running diary” where I’ve written down some of my ideas and reasoning behind writing GPU accelerated Fortran code with the assistance of LLMs and agentic ish workflows. You can find them on my website. Part 1: discussion on software architecture and design https://jorgeg94.github.io/posts/2026.04.28-vibe-fortran/ , Part 2: GPUs using OpenMP target offloading https://jorgeg94.github.io/posts/2026.05.01-vibe-fortran 2/ , and currently Part 3: GPUs via standard parallelism https://jorgeg94.github.io/posts/2026.05.26-vibe-fortran 3/ I still need to write a post on my “setup” for AI assisted coding but I thought it would be nice to first discuss how I set things up for my AI’s success. Cheers 6 Likes sumseq https://fortran-lang.discourse.group/u/sumseq 2 I will be sharing some new standard parallelism results on NVIDIA, AMD, and Intel GPUs soon - stay tuned 3 Likes jorgeg https://fortran-lang.discourse.group/u/jorgeg 3 This is super nice I am working on something similar. I’ll update here too
