A developer migrated over a dozen Fortran procedures to new modules with generic interfaces, a task that would have been a large effort but took only a few days with the help of AI coding agents. The …
Version 0.1.0 of mqc, a software package for many-body expansion calculations, has been released. The tool implements fragment-monomer to dimer, trimer, and tetramer coupling with truncation at trimer…
A technical blog post by an author writing a paper on the Chebyshev-Jacobi method argues that, contrary to common belief, Gauss-Seidel is not always faster than Jacobi, and presents a modern convex op…
A developer forked the fortran-lapack repository to make more procedures pure, enabling more of their R package translations to be designated pure. The purity analysis and refactoring were performed b…
Scientists are using artificial intelligence and large language models to rewrite old code in modern languages, as demonstrated by a developer who translated Matplotlib to pure Fortran using AI assist…
Apple's Accelerate framework outperforms GitHub Copilot-generated BLAS Level 3 dtrsm routines on Apple M1 and M2 chips, with performance jumps at matrix sizes that are multiples of 8 attributed to the…
A developer known as jorgeg ported the libcint quantum chemistry library from C to Fortran using Claude, finding a 5-8% performance penalty compared to C. The port, which is derivative work under Apac…
A developer ported the libcint quantum chemistry library from C to Fortran using Claude, finding a 5-8% performance penalty compared to C. The developer plans to create a new repository for the Fortra…
A developer has created a transpiler from the J programming language to Fortran using OpenAI Sol, enabling batch translation and a REPL that translates and runs Fortran code on the fly. The tool works…
