Thought experiment:
You have a #supercomputer with infinite FLOPS (FP64 or whatever else you prefer) and infinite memory bandwidth - what is now the biggest bottleneck on your science advances? (Or business value generation, or whatever your supercomputing mission is)
Procrastinating thought about #supercomputing …
When does the world of #HPC lose the most productivity temporarily - during November when everyone is focusing on #SC25 - or during July/August when large numbers of people are taking holidays?

There's also src/sbatch/opt.c that deals with the submission scripts. Our cat will be psyched, there's a requirement for saying a "Magic" word! hehe. #hpc
I have just set the first video public from our #LLVM #Meetup in #Darmstadt.
Expect to see more and more videos coming online as we bring online all our recordings.

I scored three more infiniband cards today. #hpc
Ok #hpc peeps! Seeing as the ‘sky doesn’t have polls, and I know a load of y’all are on here, can we try an informal pseudo poll?
Who all’s planning on being *physically* present at #sc25 in St. Louis this fall?
Bash the 
if you are, or drop a comment.
I’ll report back!

Interested in HPC compliant data analysis workflows?
I am offering an NHR (German association for HPC resources) course for building and using Snakemake workflows on HPC clusters in Mainz, Germany! Two days: 9. & 10. December 2025 on-site.
To find out more and perhaps enrol, visit the course page: https://indico.zdv.uni-mainz.de/event/39/
IndicoBuilding HPC-Compliant Snakemake Data Analysis WorkflowsOverview This tutorial equips participants with the essential skills to design and implement High-Performance Computing (HPC) compliant data analysis workflows using the Snakemake workflow management system. Through hands-on exercises and practical demonstrations, attendees will learn how to harness the power of this workflow manager to utilize HPC resources effectively and ensure reproducibility in their data analysis workflows. The Snakemake workflow system is widely used in...
Come work with me and tackle some of the most rewarding and interesting topics in high performance computing! PhD with experience in #HPC preferred, many research opportunities available as we push forward the state of data center automation for academic workloads with modern tools and methods.

Dear HPC users,
We invite you to take part in a research survey that explores how researchers approach computational reproducibility, especially when working with HPC and cloud infrastructure. The goal is to better understand current practices, challenges, and needs around reproducible research workflows.
Survey link:
https://ec.europa.eu/eusurvey/runner/computationalReproducibility2025
The survey takes approximately 10 minutes. It is anonymous and entirely voluntary. The results will be published in a research paper and also contribute to shaping best practices and training resources that support reproducible science, such as those developed in the de.KCD project.
The survey is open until August 31st, 2025.
Your time and input are greatly appreciated in advancing more reproducible and reliable computational research.
The 13th MVAPICH User Group (MUG) Conference is coming up (Aug 18-20 in Columbus). It's a great event for focused technical presentations around MPI and network performance. Great speaker lineup too. Wish I could make it in-person, but virtual attendance is free

Never underestimate the power of “wall clock as a benchmark” folks!!
Some beautiful insights from our good friend @jeffgeerling.com who always measures twice, and cuts once!
Although I do always love me some unnatural acts of advanced storage violence with “dd” and chums!

You aren’t wrong about layers and layers and layers. I was benching a btrfs the other day with what should have been wicked slow storage. For all my use cases it went like an absolute

Sometimes you just want a kernel to build fast. If it does, I’m a happy camper. 
We're expanding our gallery space in August to set up a Thinking Machines: Connection Machine with an event to celebrate the 40th anniversary. Join as a BOOTSTRAP member to attend the preview and get a behind the scene peek at the CM2's HOST, a Symbolics 3670 LISP machine, as we restore and recover its *LISP (StarLISP) programming system.

I wrote up some notes on how to approach I/O and storage benchmarks in RFPs. I normally don't post here about updates to my digital garden, but I think this page is tidy and useful.
Glenn's Digital GardenbenchmarkingThere are two ways to approach benchmarking. System-level capability: This tells you the best- and worst-case performance you can get out of the system regardless of whatever workload (or mix of workloads) you throw at it.

This is a quick way to find potentially slow links on an Infiniband fabric using clusterkit and a mixture of find, cat, and AWK.
