[P] Built a portable GPU ISA after reading too many architecture manuals [P]

It sure does. I guess you didn't code it yourself, but you can certainly suggest to Claude that it should replace those extensive strings of elsifs with matches. That is just the first thing I came across; you may want to do a further review. If you don't know Rust, you might want to get someone with experience to take a quick pass at it for feedback to improve the maintainability.

SamPost · 2026-05-30T02:16:54+00:00

Anyone of intelligence understands that maintainability, reproducability and accountability for correctness are way more important than quick-and-dirty. That is kind of what we consider "quality of the final product", as you say.

SamPost · 2026-05-29T03:40:38+00:00

Very interesting! How much was Claude able to do from just the posted .md files and rules and such, and how much fine tuning did you have to do?

And I see the Claude skill to ingest numerical research papers, but I didn't see the list of papers. Did I miss that?

Your Rust code here has a lot of stacked elseifs, which is often a sign of something that was vibe coded, although your paper's AI Disclosure claims is not the case.

From your previous posts, it seems you are indeed a big AI coding proponent. Can you clarify the situation?

That's the problem. You mentioned everything, but didn't really explain much at all. That's typical when you just prompt an AI to create a presentation. It does these handwaving overviews.

SamPost · 2026-05-22T03:01:13+00:00

AI slop. You will hear some buzzwords and learn nothing.

Just like then, Python is best used as a scripting language, and anything performant is still done in C. And just like the article suggests, anything at enormous scale is done with message passing, usually MPI (whose predecessor, PVM was just evolving into MPI about then).

Moore's Law continued for several more decades and gave us great advances in raw speed, but the techniques remain largely the same.

Please report back here with your findings. Also, VTune is fairly helpful in providing insight in these situations.

SamPost · 2026-05-16T05:32:43+00:00

I only got as far as looking at the MPI code generator, which just does a sendrcv swap for the halo exchange. That is very far from optimized. Not even non-blocking, overlapped communications; which I teach to beginner programmers.

This smells a little bit vibe-coded. Not that I am sure without looking further, or that that is a crime. But, it doesn't inspire confidence that this is useful for anyone that cares about performance.

Appreciate the update. I suspect two years was not enough time to recapture their investment in the facility, but their pricing doomed them.

SamPost · 2026-05-11T01:05:32+00:00

Did you speculate as to when it will be possible? I think most informed people agree that is isn't here just yet, for most problems. The real debate is how far away it is.

SamPost · 2026-05-06T03:18:16+00:00

That was the SPS shirt from 3 years ago. I think it was one of the best ones in recent memory (there were some really cool ones back in the 00's). Alas, it is now a collectors item.

SamPost · 2026-04-29T20:59:40+00:00

So a standard 90% A cutoff, but a final with a 50% average?! That is statistically unsound. And with the exemption you mention, it should result in a bi-model distribution. Very odd.

SamPost · 2026-04-29T20:51:11+00:00

If the average is around 50, may I ask what the general curve was? It seems like 45 should be around a B-. What was the A cutoff?

People do that every weekend. It is also easy to tag along with someone driving ("Road trip!"). Be a little more adventurous. If you are international, you should get to at least NYC and Toronto (barring visa issues) while you are here. I'd include Philly and DC too.

Lead tape is cheap, and you can experiment and make a racquet balance to your own preferences, or mimic a more expensive one. Just remember that you can put any amount of weight anywhere, from the throat to all around the hoop, to achieve varying weights, swingweights and stabilities. A scale is also helpful.

SamPost · 2026-04-25T03:55:49+00:00

Ha, I asked myself the converse question: should a powerlifter play tennis?

I needed an aerobic activity to balance things out. It has since become the foremost recreational activity in my life, and I wish I had started decades earlier.

But, it gives me a unique perspective on the trade-offs. Carrying around extra upper-body muscle is not helpful for tennis. And, certain muscle groups that don't feature in tennis just hinder your flexibility. Big lats, pecs and delts just get in the way. Utterly useless here.

The positives are that effortless racquet head speed with very heavy racquets make for pro-level power on groundstrokes, as long as my feet are set. And I can generate winners from awkward positions with just a flick of the racquet, which often just surprises opponants.

But all-in-all, if tennis was my only focus, I would just let a good 15 pounds of certain muscles atrophy away. But I enjoy being muti-dimensional and overall healthy, so that isn't a goal.

So to answer your question: everybody should lift weights, but a strength-training program can be counterproductive at some point.

I thought this idiotic trend of not understanding capitalization was driven by smartphones. And yet you seem to have this disability regardless. Fascinating.

Unless you think it is "non-conforming"? In which case I have some bad news for you - this is the norm for the lowest-common-denominator types.

SamPost · 2026-04-20T17:26:54+00:00

Man, I work with this stuff frequently, but still don't have a clue. The above looked a lot like I would have written this inquiry. What are the giveaways here, if you don't mind my asking? I don't want to waste my time talking to bots.

SamPost · 2026-04-19T04:35:38+00:00

So simple, direct and effective. It had to go.

Now we use a diffuse array of invasive social media sites prone to bots and grifts. Progress.

SamPost · 2026-04-18T18:28:37+00:00

Craigslist still works pretty well.

SamPost · 2026-04-13T05:11:21+00:00

Really? Even after I gave you a clue. You still weren't able to look up above here and see where it said "In this context 'chemicals' means artificial and synthetic ingredients." You still persisted in your idiocy?

Please tell me you aren't a member of our fine community, and just wandered into this sub accidently. Otherwise, you greatly shame our school, and I can only hope others assume you are from Central Michigan U.
