Tutorials and Workshops kick off this morning!
Some Student Programming events are also running today:
- HPC/AI Crash Course - 8:30AM until 3:30PM in Room 263. Please note this required preregistration
- Career Panel - 3:45PM until 4:45PM in Room 263
Wonderful view of the St Louis skyline coming in on my flight. Eagerly anticipating this year’s #sc25 #hpcignites

The TLDR is that a really big HACC job ran on Frontier with a bunch of new algorithmic optimizations. Neato.
Safe (and uneventful) travels!

Each day we'll explore a fun optimisation in C or C++; some low-level, x86 or ARM-specific, some high-level. Hope you'll join me!

Dear all #HPC and #AI/#Quantum/#RCD and #Supercomputing folks and friends: It's just 3 years since we launched the survey.hpc.social/results/hpc-... that led to the creation of the multi-faceted set of resources of the hpc.social website and tools. This is just to say THANK YOU and see you at #SC25!

@glennklockwood.com ah, there is this:

I just get pointed to the mention of DOE’s new public-private partnership model. But I’m failing to find out more information. Same thing with the new 100K GPU NVIDIA system at ALCF.

I thought Lux was the OCI partner system. Discovery is OLCF-6 and doesn’t include Oracle.

Granted, my sample size is 3 and I believe all came from Apple.
#SC25 will open with a 2-day #HPC Crash Course based on OLCF training at ORNL.
The course is free with Student Program registration, but spots are limited.

It’s a wonderful game… So many expansions and high replay value, too!

- Incredibly useful for experts in a field that are able to correct for their errors
- Really dangerous for layfolk who don’t know what they don’t know
August 1, 2025 AMERICAN ECONOMIC ASSOCIATION Committee on Economic Statistics and Committee on Government Relations Statement from the American Economic Association on the Dismissal of the BLS Commissioner Leaders of the American Economic Association express their grave concern over the dismissal of the Commissioner of the Bureau of Labor Statistics (BLS) earlier today. The independence of the federal statistical agencies is essential to the proper functioning of a modern economy. Accurate, timely, and impartial statistics are the foundation upon which households, businesses, and policymakers make critical decisions. Undermining the independence or credibility of these agencies threatens the integrity of the information that markets, institutions, and the public rely on every day. Measuring the vast and dynamic U.S. economy in real time is inherently challenging. It is standard practice for statistical estimates to be revised as more complete and higher-quality data become available. These revisions reflect the commitment of statistical agencies to accuracy, transparency, and methodological rigor-not failure or bias. The BLS has long had a well-deserved reputation for professional excellence and nonpartisan integrity. Safeguarding this tradition is vital for the continued health of the U.S. economy and public trust in our institutions. We call upon elected officials to respect and preserve the independence of the nation's statistical infrastructure. Lawrence Katz President, American Economic Association Katharine Abraham President-Elect, American Economic Association Karen Dynan Chair, American Economic Association Committee on Economic Statistics Kenneth Troske Chair, American Economic Association Committee on Government Relations

This is a big deal
💥Spack v1.0 is out!💥
This is a huge milestone. We reworked the core to add compiler dependencies, and we're introducing a stable package API.
🚀1.0 also adds concurrent builds, better includes, and much more -- read it all in the release notes!

Why are they called "relaxed" atomics, but whenever I have to use them, I become very stressed?

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.
The President's Budget request as released yesterday will gut scientific research. Why should you care?
1) Science is fundamentally a jobs program. Many 100,000s are employed to do science and work for you, the US taxpayer.

I want them to be successful because I think something else is needed. But running large apps at scale is always gonna be a bottleneck for any non von Neumann architecture.

- For Next Silicon, unlikely/non-parallel can execute on device via RISC — which is something that Samba Nova cannot handle at all(?)
- SW stack is completely different
When will they learnnnnnn

int main() {
int a = 0xE + 1; // compiles
int b = 0xE+1; // doesn't
}
Yeah, wow that’s incredibly annoying.
I am able to do it with only one additional template instantiation though!

At the end of the day, everything is a data movement problem.
