What an amazing exhibition experience last week was! ISC High Performance was an adventure, and we are delighted that we were able to welcome visitors not only at our joint GCS stand, but also at our
JUPITER booth.
Find out all about our experiences, activities and successes right here: https://www.fz-juelich.de/en/ias/jsc/news/news-items/news-flashes/2025/isc25-action-packed-days-dedicated-to-jupiter-quantum-power-and-networking
#ISC25! #JUPITER #HPC #Supercomputing #Quantumcomputing #FZJ
The #isc25 is over and I half-recovered from the weekend, too. Time to continue my thread summing up the #SnakemakeHackathon2025 !
To me, an important contribution was from Michael Jahn from the Charpentier Lab: A complete re-design of the workflow catalogue. Have a look: https://snakemake.github.io/snakemake-workflow-catalog/ - findability of ready-to-use workflows has greatly improved! Also, the description on how to contribute is now easy to find.
A detailed description has been published in the #researchequals collection https://www.researchequals.com/collections/hm1w-cg under https://doi.org/10.5281/zenodo.15574642
#HPC Hallway Huddle alert! ~2 hours to next #hpc-huddle! Will we have lots of news from #ISC25 and other happenings this past week? Join to find out! https://hpc-hallway.github.io/The-Hallway/
Interesting take from an #Nvidia engineer I met at #ISC25: "Do you need IEEE-754 compliant #FP64, or do you need digits? Digits we can get you through FP64 emulation."
Not sure what to make of that. Things were an absolute mess before the IEEE-754 standard, and I wouldn't want to ever go back to that. No standards means you cannot at all port software between hardware architectures even from within the same vendor. Having to re-architect software for each and every new chip is not gonna happen.
Returning from the #isc25 I will continue this thread with something applicable everywhere, not just on #HPC clusters:
Workflow runs can crash. There are a number of possible reasons. Snakemake offers a `--rerun-incomple` flag (or short `--ri`) which lets a user resume a workflow.
This contribution from Filipe G. Viera describes a small fix to stabilize the feature. Not only will incomplete files be removed after a crash, now it is ensured that all metadata with them are deleted too, before resuming: https://zenodo.org/records/15490098
Waiting for my train and going through slides of a BOF from the #isc25 . Apparently, students prefer tutored online courses.
I as a lecturer always prefer onsite courses. Spiced with lots of exercises. Such that I get an immediate impression of proceedings and reception of the material.
Yes, I understand the need-to-travel overhead when living in somewhat remote areas. On the other hand: All those demanding online or even hybrid courses - have you considered that the average participant might learn less? The literature supporting online courses at least is rather underwhelming.
Plus, actually meeting people is way better than chatting online. Same with conferences. I just me people from @SURF and other places whom I only met online before. Such a difference!
Then again, I only travel by train - which cannot expected by everyone ...
Oh! Here at the #isc25 I noticed, I got my first #nanopub PR merged: https://github.com/Nanopublication/nanopub-py/pull/193
Remember the #blockchain hype? Enormous potential! Right? Every “expert politician” knew about it. Right?
And now? #AI Here, at the #isc25, lots of vendors are exclusively focussed on AI. Now, AI in research is different to the blockchain hype. Still, there clearly is hype, too.
And I wonder what will be established and recognized by a wider community when the hype is over. Protein structure prediction, perhaps neoepitope prediction, some clinical diagnostics support, event selection in collider physics, etc.?
And where will we agree that some path we followed was completely foolish?
Today tooting from the #ISC25 - the International Supercomputing Conference. What better opportunity to brag about something I've done to facilitate using GPUs with Snakemake?
Here is my contribution, simpler job configuration for GPU jobs:
https://doi.org/10.5281/zenodo.15551797
Not alone though: Without valuable input of @dryak . Without him, I would have overlooked something crucial.
And when we talk about reproducible AI, my take is that we ought to consider workflow managers, too. Something which protocols what you have done with little effort.
The Wi-Fi at #DeutscheBahn certainly improved: Have been able to do two (mini) PRs to software projects during my ride to #isc25 , already.
I remember the days when I was stuck with a `git clone` with 2 bytes / sec somewhere at the Dutch border (still in Germany).
This morning, I am travelling to the #isc25 and hit a minor bug on #researchequals. Hence, no updates in the collection.
But still a few to describe without adding the latest contributions:
For instance, this one (https://zenodo.org/records/15490064) by Filipe G. Vieira: a helper function to extract checksums from files to compare with checksums Snakemake was already able to calculate. Really handy!
On my way to Hamburg, #ISC25. The place where #HPC folks gather to learn about some new hardware trends.
Luckily, I will meet some like minded people, too. Those concerned about #usebility , #teaching , #ReproducibleResearch and so on.
By becoming the fastest #supercomputer in Europe JUPITER propels European Computing Power. #exa_JUPITER, developed by @fzj_jsc and owned by #EuroHPC JU, ranks 4th on the June 2025 #TOP500 list of the world’s fastest supercomputers and stands as the most energy-efficient system of the top 5 of the listing, which was presented today at the International Supercomputing Conference #ISC25. https://www.fz-juelich.de/en/news/archive/press-release/2025/jupiter-supercomputer-propels-european-computing-power
At this 40th anniversary event, under the theme “Connecting the Dots”, #ISC25 will focus on the integration #HPC with #AI and #QuantumComputing
The goal is to bridge gaps across scientific research, engineering, and business applications
