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'm excited to share jaxion, a differentiable Python/JAX library for fuzzy dark matter (axions) + gas + stars, scalable on multiple GPUs

⭐️repo: github.com/JaxionProjec...
📚docs: jaxion.readthedocs.io

Feedback + collaborations welcome!

Here's an example of Google search bar getting it wrong: answer should be 4.3*10^-3

I noticed Google search is no longer reliable for quick unit conversions & calculations.
So I built a simple online calculator

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-...

Excited to be at Supercomputing 24 #SC24 this week! Catching up with friends and colleagues, meeting new people, and catching the latest advances in high-performance computing. Booths are being set up:

I may occasionally share a picture of my wife's and my puppy too

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: https://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?
