My implementation of the GaussSeidel smoother using a Diagnol direct access scheme in OpenFOAM as compared to the default GS smoother LDU gives almost ~50% improvements in cache misses and hits for a structured 3D cavity tutorial. Profiled using the amazing LIKWID profiler. Will share a deep technical report soon. Check it out and use - https://github.com/amartyadav/DIAGaussSeidel-Smoother-OpenFOAM

Been working on my Linux machine for 3 months now at work - comp. physics, hpc, etc.
Tried working on my MBP yesterday (after around 5 months of not using it for development) - while a superior machine h/w wise, I really couldn't stand macOS.
Linux just works - better even.

My latest blog post explores a Multi-Material Thermal Analysis using HYPRE BoomerAMG with a custom POSIT accelerator called Uttunga, and compares it to the x86 IEEE 754 standard.
