Jacobi Microbenchmark

A microbenchmark measuring the performance of various programming languages and parallelisation strategies by solving a matrix-free linear system using an iterative Jacobi method. Essentially solves the diffusion equation. Zig and C are bloody fast.

Melvin.py

Github

A pseudospectral solver framework designed to simulate 2-dimensional advection-diffusion problems. It is written entirely in Python and leverages CuPy for GPU parallelisation. It has been used to simulate thermohaline staircase formation, Rayleigh-Bénard convection, and the resistive tearing instability.

Dirac Cluster Challenge

Github

Starting code for a parallel programming challenge I ran in 2022. Includes simulations of a general N-body problem, and a fully implicit fluid solver simulating Rayleight-Benard convection. The event taught students how to program GPUs and multi-core CPUs in Python.

GFP Simulator 9000

Github

Simulate the interaction between molecules GFP-CRIB and Rac in 2 or 3 dimensions. Core numerical solver is a custom finite-element method. Developed for the Beatson Institute for Cancer Research. Technically works, but not particularly readable.
