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.

My work for the month is to optimise the matrix adressing scheme of OpenFOAM to reduce cache miss. Initial idea is to replace the LDU Matrix addressing scheme with Diagnol matrix addressing scheme using multiple arrays for structures meshes. Will check it out on a simple 2D Poisson equation using Gauss-Seidel solver to check performance benefits, and will eventually proceed to introduce a new solver as a plugin if benefits are noticeable.
Wish me luck.
