I have a small set of linux machines (~5) that are mostly sitting idle. How can I turn it into a modest #CoW (cluster of workstations) so that people can easily submit long-running jobs to it?

Jobs will be mostly written in #rstats and #python .

What's a good entry-level setup for this? Easy to maintain, easy to use, nothing fancy.

I haven't done anything like that for at least 10 years, I'm sure things have moved on since then.

Thanks!

Last year at the Open Science Retreat (#OSR24NL) I have been introduced to nanopubs by @egonw and created my first nanopub declaring citations for a paper using CiTOs (citation ontologies).

Now, travelling to #OSR25CH, due to issues with the train network foreseen with plenty of time, I used the opportunity and created a new one ( https://w3id.org/np/RAicq7k9QHX8EG8ho7Baib9GxHsU18O0tyFCZ4tbbGGPA ) for my latest publication on teaching #Snakemake on #HPC systems.

The teaching material is — again — in desperate need of additions and overhaul, but that is for another day.

Wow, workshops are now included in the #SC25 technical program registration. This is incredible; workshops are an invaluable place to have focused, deeply technical discussion and build community with a high concentration of like-minded individuals.

What an honor to start the #IWOCL conference with my keynote talk! Nowhere else you get to talk to so many #OpenCL and #SYCL experts in one room! I shared some updates on my #FluidX3D #CFD solver, how I optimized it at the smallest level of a single grid cell, to scale it up on the largest #Intel #Xeon6 #HPC systems that provide more memory capacity than any #GPU server.

Newest inference specific chip from #Google, 6x more high-bandwidth memory (192 GB) and excitingly 30x less power per calculation compared to 7 years ago.

I'm glad I'm not the only one who wonders about things like this in the middle of the night - Why are programs in #HPC called "codes" and not "code"?

Hey engineers!
Any leads for #OpenSource #CPP #software that uses C++ StdPar parallelism as their (main) parallelization scheme?
Would be quite interested in learning about such apps and domains where that is used.

New AI model developed! ‘TopEC’ analyses enzyme structures, learns their chemical reactions & deduces their function from this. Involved were the FZJ, HHU Düsseldorf & Helmholtz AI. The model for machine learning at the molecular level was trained on the JSC supercomputer JUWELS.
