Having a lot of fun scaling up massive Python/JAX physics simulations on the Frontier supercomputer with AMD MI250X GPUs -- currently hitting 3 billion cell-updates/sec on a 2048^3 resolution run 🚀

I noticed Google search is no longer reliable for quick unit conversions & calculations. So I built a simple online calculator Give it a spin: pmocz.github.io/online-unit-...

5 years ago, a ~100-line #Python N-body code kicked off my blogging journey. Today, I’ve rewritten it in JAX for blazing fast performance and ability to solve inverse problems. 🌀💥 Check it out here: philip-mocz.medium.com/create-your-...

Hi everyone, I'm re-introducing myself with the large influx of newcomers here! I'm a computational physicist and sometimes blog intro to numerical simulations in Python. All my code is at github.com/pmocz and tutorials at philip-mocz.medium.com

Interested in how different methods for computational fluid dynamics compare? I'm sharing some intro Python scripts on solving the isothermal compressible Euler equations with Finite Volume, Spectral, Lattice-Boltzmann, and SPH methods here: github.com/pmocz/cfd-co...

Hi everyone! I like to share intro Python tutorials on simulation methods. Here's an almost one-liner at its core on solving the wave equations with finite difference. 👉 Follow me for more! philip-mocz.medium.com/create-your-...

Interested in creating your own numerical methods for computational physics? I've written a series of intro tutorials with Python code on my github that I'd like to share: medium.com/@philip-mocz

I was looking at archived data on the aasjob register, limited to R1 TT jobs in the US in astro. Positive growth in 2022. Does anyone know why? Is it make-up from the drop during the pandemic?

With advances in AI and compute, I'm thinking we'll see in our lifetime cosmological simulations with initial conditions to reproduce our local galaxy population. Sims. may move from being statistically representative to trying to recreate the real thing
