Breaking from JCC: GROMACS reaches a new height in #HPC scalability! @mpibp.bsky.social @mpi-nat.bsky.social onlinelibrary.wiley.com/doi/full/10....
Scaling of the GROMACS Molecular Dynamics Code to 65k CPU Cores on an HPC Cluster
We benchmarked the performance of the GROMACS 2024 molecular dynamics (MD) code on a modern high-performance computing (HPC) cluster with AMD CPUs on up to 65,536 CPU cores with input systems ranging...

I have some good news and some bad news for my #HPC friends. Ansys 2025 R1 is now available....
Bad news is that it is now twice the size of 2024 R2 (looking at the number of DVD ISOs compared to last release).
Best of luck to everyone...

Today's #AOC made me do something I'm not too proud of... Needed a hashmap but I wanted to use 4 it's as the key... There is no hash for arrays, so I converted the four numbers into a string...

Hello #HPC,
I have put together a gist that contains the steps that I (mostly) took to build WRF, WRFDA, and WPS. Please let me know if you experience any issues with the steps taken.
Looking forward to seeing how we use this at the EVIDEN both at #SC24.

Well, after another day of trial and error, I got WRFDA working on Rocky Linux 9.
That was a fun experience.
Fingers crossed that we finish the demo for #SC24.

Is there a WRFDA compilation guide out there somewhere that someone not in the weather prediction scene can access? My sanity can only last so long when trying to read WRF's configuration and compilation code on their github...

I won't just post things about programming, scientific computing, high performance computing, and containerization, sometimes I'll post pictures of my cats.
