Thank you windows for the message...

I just completed all 12 days of Advent of Code 2025! #AdventOfCode adventofcode.com Another great year of puzzles.

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...

Happy New Year everyone. Remember to update all of your copyright notices from 2024 to 2025...

Looks like OpenFOAM gave us a Christmas present... Time to get this release available to our users.

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...

Well, day 14 part 2 of #AOC was something... Good luck LLMs...

The Linux kernel is being updated to allow 4096 cores... www.phoronix.com/news/Perf-Su...

Perf Support For 2,048 CPU Cores Is Becoming Not Enough - Patches Bump Kernel Limit

Currently the Linux kernel's 'perf' performance monitoring subsystem has a limit on 2,048 CPU cores for its CPU map that is set by the MAX_NR_CPUS value

So, a friend and my wife are also trying to save Christmas. My friend is kicking the rust off of their Python... While my wife decided to do it in Excel and got both stars... #AOC

Got the tree up. #caturday

Who else is going to be helping to save Christmas this year? #AOC

Is there a max layer size option in Docker... I'm ok if I lose some image efficiency... #HPC #PODMAN #DOCKER

Anyone want to guess when I lost Internet and when it came back?

Well, they didn't send us any of these to test (play) with...

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. gist.github.com/schrummy14/6...

Installing WRF, WRFDA, and WPS on Rocky Linux 9

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... #HPC

My cats have not been happy with me today.... #blameDST

Don't want to worry about large function inputs that will change as you add new features? Try this simple trick...🥲

Amazon EFA broke... And hardware acceleration doesn't work... Working with containers is always exciting.

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

Love creating 50GB+ containerd images. At least we'll have GPU compute enabled now.

Bluesky now has over 10 million users, and I was #1,811,670!

Sorry rust, but I'm staying with C with classes for the better MPI experience...
