About

I’m Dayo Ntwari, Senior Computing Specialist in the Department of Statistics at the University of Oxford, where I manage Linux infrastructure and HPC systems.

This site exists because HPC documentation is often terrible. I write the guides I wish had existed when I was setting things up.

Topics covered: SLURM, MPI, containerisation with Apptainer/Singularity,
storage, conda environments, and general Linux for research computing.

If something here saved you an afternoon, consider buying me a coffee.
