Virgile Andreani ⏚ 🇵🇸Pretty impressed by the speed of Python 3.14 compared to 3.13 😲
AmartyaMy 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.
Engineering KioskFortran ist nur Legacy? Nicht ganz.
Mit Martin Diehl sprechen wir über moderne Fortran Standards, HPC, OpenMP, MPI, Coarrays und warum hinter NumPy, SciPy und LAPACK oft Fortran steckt.
Plus: Compiler, LLVM, Community und Tooling.

IBM outlines quantum-centric supercomputing architecture

James R.B. EastwoodIt's amazing how much value I can unlock in my projects by asking naive questions like "which computing cluster are we talking about using?" which leads my team to remember that we have access to a second computing cluster, and also we have a staff member with credentials and knowledge of the system, who also has free time blocked off next week for "science stuff" and suddenly the Scarce Resource Allocation problem vanishes.

Might publish a blog or two in a few weeks about my work with OpenFOAM, different profilers, and an implementation of an LBM CFD kernel on RISC-V with POSITS.
What a great company to be working for. Learning so much!

AndreasIn #FElupe, a #python package of mine, I changed the API of a function: the output included two return variables (boundaries, loadcase), where the second one is nowadays mostly unused. So I added a new argument return_loadcase=None, which does not change the return behavior, but marked as deprecated. In a future major version, return_loadcase will be False by default. Now all users have at least one major version time to update existing scripts. Is this good practise or could this be improved?
