Transpilers from C++ and C to Fortran
A developer has created partial transpilers from C++ and C to Fortran, branching from an existing C-to-Fortran transpiler and using Codex and Claude. The mapping of C++ constructs, including std::mdsp…

Arm Community's overview of LLVM 22 highlights vectorization improvements and updates to the Flang Fortran compiler, as noted by user ivanpribec on August 6, 2026. The release focuses on enhancing per…
Egor Howell, a data scientist and YouTuber with 69,000 subscribers, published a blog post on Towards Data Science about using Claude to build a $200k+ ML resume, in which he lists Fortran under 'Exper…
A developer achieved bit-reproducibility between CPU and GPU calculations for transcendental functions in Fortran by wrapping the bitrep C++ library and adding OpenACC/OpenMP directives, with a perfor…
Zane Hamilton's Booth compiler now compiles Fortran 'do concurrent' kernels to GPU machine code, supporting AMD RDNA 2/3/4, CDNA, Nvidia PTX, Tenstorrent, and Apple (WIP), with its own CPU backends fo…
A developer known as simong on the Fortran Discourse forum is developing a 2D drafting package in Fortran and Tcl, drawing on 40 years of CAD experience, and is using Claude to implement a small scrip…
A developer released fortxarray, a small Fortran library for writing NETCDF files compatible with Python's xarray library, designed for simplicity and ease of use. The library, which leverages Google …
A developer used GPT 5.6 Sol to create a time series analysis library in Fortran by translating 48 R packages, with plans to add more from R and other languages. The library includes a program for aut…
A developer used AI models Codex and Claude to create a Python-based transpiler that converts C code to modern Fortran, successfully translating several numerical C programs. The tool is being tested …
LFortran version 0.61.0 failed to compile the Xfoil aerodynamics code due to a bug in handling the INCLUDE statement in fixed-form Fortran, which has now been fixed in a pull request by LFortran devel…
A commentator reflects on the failure of Intel i860 chips, which offered 40 MFLOPS and were versatile for PCs and supercomputers, attributing it to major computer companies like DEC, Sun, and Cray pla…
A Fortran developer proposes adding a RESIDENT locality specifier to DO CONCURRENT to prevent implicit offload copying in systems with separate memory address spaces, allowing selective host-only para…
Fortran developers report positive experiences using Anthropic's Claude AI assistant for coding tasks, including writing test programs and debugging projects. Users praise Claude's ability to generate…
A developer refactored Fortran code for GPU acceleration by replacing inline PPM slope computations with pure subroutines callable from do concurrent loops, improving code clarity and enabling better …
Fortran developers are prototyping separate TYPE and CLASS keywords to improve code simplicity and robustness, with LFortran already implementing a templates/generics prototype for comparison. The ini…
Anthropic's Claude Mythos successfully extended a Fortran-to-C transpiler to also support C++, fixing 14 bugs and passing 44 of 86 test targets in a GARCH volatility project. The AI worked for 2.5 hou…
A developer has created sqr, a self-contained relational database written entirely in Fortran, using Claude Opus 4.8 to generate approximately 13,000 lines of code. The engine supports indexed, transa…
The AI boom is pulling GPU vendors away from double-precision (FP64) hardware essential for scientific HPC, as NVIDIA, AMD, and Intel prioritize low-precision AI cores. New chips like NVIDIA's B200 an…
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 pro…
