Memory optimization is the best way to write high performing CUDA kernel for AI
by thecongluong | 2025-06-06 14:20:29+00:00
Is the current state of cuda kernel for AI applications all about memory optimization ? Compute units (tensor core) are so fast now and memory is lacking behind. So the highest performing kernel are the one that best utilized memory and data transfer to constantly feed the tensor core. By that assumption, one can become a good kernel programmer if they can master the art of memory loading ? BTW, I've never used atomics, are they useful in writing kernels for DL applications ?

funny, I still had this open from when I saw it mentioned in another thread on HN

https://wikipedia.org/wiki/Brandolini%27s_law

Debunking disinfo takes significantly more energy than it did to create it, although I have no more than anecdata to back it up I have yet to find anyone who disagrees.

So, I too would like to believe that the truth prevails but imo it only does so when its champions are incredibly persistent.

I don’t want to disagree with you but I have a hard time with preaching that people are not be personally responsible for themselves.

I get your point that genes are important and some are blessed while others are not. But regardless what your genes are, you need to find a way to take care of yourself. You are not entitled to someone else taking responsibility for you and your problems.

This is extremely good advice! In particular, I agree completely the key is to figure out mentally how not to frame the problem as a willpower issue or as overcoming hunger. That is a setup for failure and feelings of shame. Making it about self-control and avoiding temptation is the worst thing you can do.

Yeah I instinctively did the same thing once I finally was able to bring myself to counting calories. Once you have a budget, you want to game the budget to feel full, so it makes veggies start looking a lot more attractive, and things like chocolate easier to avoid.

For me one of the big byproducts of this thinking is that my feeling of fullness was mis-calibrated a little bit. As a result, when I’m full according to my calorie counter, I think about how what I’m feeling is not hunger but the correct level of full. I’m recalibrating what full means to me, and believe it or not it actually helps me to not feel like I’m trying to overcome hunger.

It's hard to wrap your head around that when you got fit working out. They will firmly believe that obesity will be solved by people working out and having a stricter diet. I took me years to understand that it's doesn't work for an entire population. Honestly, even if that happened (everybody started working out), people would have a lot of problems with body image, as we can see in teenagers boys nowadays.

It is a logical fallacy if used as part of an absolute claim, but it doesn't make it always wrong when used in general statements. Some slopes are slippery, we can look at history to see this. We can't claim all slopes are slippery, this doesn't mean that no slope is slippery.

People aren't starting with axioms and then defining what absolutely will happen. People are discussing trends that appear to happen generally, but there will be exceptions. Going to college leads to a better job is a slippery slope, it doesn't always happen, but going to college is still good advice (and even better advice if one is willing to go into detail about the degree, the costs, the plans at college, and so on).

If we want to reject something as a logical fallacy, we need to consider if the other person's argument hinges on something always happening as some sort of logical proof, or if it hinges on it happening only at or above some threshold. If the first case, pointing out a slippery slope argument is a valid counter, but in the second case, it isn't and instead leads to two people talking past each other (one arguing X happens often enough to be a concern, the other arguing that X doesn't always happen, both statements that could be true).

No, we don’t have to give some people the benefit of the doubt. When someone tells you who they are, listen. And I’m not talking about the patsies being interviewed here.

Tell me, when are our taxes supposed to go down from this? This year? Or next? Or are we going to spend the money some other way instead? What was the point of any of this?

A couple of years ago, I was researching modern food science (for unrelated reasons). What really struck me was how focused we are on product longevity. Everything must have low available water in order to survive warehouses, transit, and shelves. Sugar, sodium, oils, and phosphates are all just tools to accomplish this.

Put another way, the bag of chips at the American grocery is _designed from concept to factory_ to be unable to support living beings. Microorganisms would die from dehydration trying to eat the chips. But due to a bug in human psychology, when we eat them we just feel more hungry. There only regulating feeling we get is guilt.

Looking more through this blog, it's clear that even if there's a human directing it, it's just blogspam. Every post is filled with surface level drivel and tons of affiliate links.

Look at their most recent post about the horsehead nebula: https://astroimagery.com/astrophotography/deep-space-astroph...

It's just straight up bad advice with affiliate link after affiliate link after affiliate link.

Why? Because you expect we’d nuke them for it? Hadn’t heard this before and honestly am not sure why they don’t at this point, it seems like they have less and less to lose as the war goes on. I read in the NYT a few weeks ago the pentagon estimated the escalation back in dec/jan had a 50/50 shot of going nuclear.

The most serious alternative I think is Rumble.

Bitchute allows only low quality. Odysee is slow as balls. Dailymotion has some lower limits (but might be the runner-up)

But nowadays Rumble finally allows for actual high resolution uploads, and loads quite fast, not taking forever to buffer like Odysee does. Rumble also feels like it has some momentum and content/userbase. Just don't watch their crackpot ads lol.

Rumble also has a very functional streaming product not dependent on Amazon's infrastructure, while having rewind and forever VODs, only limited to 28GB per VOD (yes I tested it!)

The data as I know it: Rumble: Allows for 1080p uploads. Old max duration was 46 mins for them, but that is no longer in place, at least as a Premium user I can upload 6hour+ 1080p videos.

Bitchute: Max resolution is low at 480p, doesn't even have quality tiers in player. Max upload size is 2GB, but uploads and watching is quite seamless.

Odysee: Haven't hit limits, those are possibly as high good as Rumble. But has been quite slow to use and upload to for me, it varies. If you upload a ton you need to deposit some LBRY. Used to have a youtube->odysee automatic sync which probably increased their "normie" population.

Dailymotion: 2 hour / 4GB limit for free users, BUT has limit on amount of videos uploaded daily that I hit mirroring some content.

Streamable: Fast and requires no account but deletes videos after 2 like days. Has its uses.

Honorary mention: X. Allows for 4k60p nowadays. But requires account to upload and view. Most have one though, and X obviously has the strongest brand recognition for the uploader (as an account X is considered "the" authorative one for people and brands), while it can be good it can also feel weird to upload long-form content there (and their TV app is totally cooked, I've tried to contact them to fix it myself to no avail)

Those that like censorship don't have a problem as they can just replace watching videos with looking at a white wall for an experience they won't get offended about.

Half their business is propaganda (the other half being surveillance); of course they represent themselves as something positive. Recognize them for what they are. Point it out to others. Advocate for banning them in schools. Warn parents that youtube kids is not appropriate for children. They do near zero curation. They don't commission creation of educational content. They are nothing like PBS (as another commenter compared them to). More generally, ads are not child appropriate. These platforms have some useful content, but on the whole they undermine teaching virtues, and in fact their entire purpose is to push the opposite.

EU countries are domestic competitors to each other economically and culturally, always have been for hundreds of years, hence the constant wars. They're only united politically in the EU when it comes to negotiating international issues.

For example, an EU country won't hesitate to torpedo another country's energy, economy or industry plan if they can score political points at home for their voters or to protect their own domestic industry players from the other members. That's also one of the reasons why Switzerland and Norway refused to join the EU.

EU is like a marriage between 27 people instead of 2, always at each other's throats but never(until 2020) divorcing. This is not the ideal environment that scales tech companies. That's why there no big tech from Europe.

Thanks for your anecdotes. Here's a couple of counter-anecdotes:

---

X has "just worked" for me since at least ubuntu 8.04 (that's 2008, april, over 17 years ago, for those counting), probably earlier.

I don't recall having any particular issues with X on the fedora machines I ran before I switched to ubuntu 8.04, but I don't recall clearly enough to be able to confidently say that I didn't have any X issues.

OTOH, I also don't specifically recall having X issues since some time around Red Hat 6 or so, which would be around 1998 or 1999, so it might be more like 25-26 years since X didn't "just work" for me.

---

About a year ago, I heard that wayland might be approaching a usable state. So I decided to give it a try on a raspberry pi that I was setting up.

It took literally about 15 minutes before I ran into a problem where I wasn't able to do something I've been doing for decades on X. And I want to stress that I was hoping it would work - I was not out to find a reason not to use wayland, I just happened to run into one inside of about 15 minutes.

I spent a couple of hours trying to figure out how to do what I wanted to do on wayland. I put a nontrivial amount of effort into trying to solve the issue on wayland. During the course of this, I found several different/conflicting pieces of advice, none of which worked for me. I think IIRC I found one option which sounded promising but which meant recompiling the compositor, or something very-nontrivial like that.

I balked at that and switched the system over to X.

And the problem instantly went away, and everything started working again. And that machine currently has an uptime of well over a hundred days.

I would love for wayland to be a thing that actually works to the point that it's a viable replacement for X, but I grow more and more skeptical every year that this doesn't happen. I Expected it like a decade ago.

The MR that caused the drama that caused the fork to happen complained about this author doing tons of work to tons of legacy code with no direct user-facing benefit without testing his changes properly. From the sentiment of the discussion I gather this isn't the first time either.

I think trying to improve the quality of such old code bases is good and "don't touch it in case something breaks" has caused more problems than it solved, but in this case the lack of testing caused X to die when someone runs xrandr. Not exactly a vague use case. Large restructuring work and taking care of tech debt is good, but it should go along with diligent testing.

Until all the work is done, I don't think this will be a very stable alternative to X.org. I also don't think many people will follow this guy to the new project because the comments on the MR seems very "this guy versus everyone else".

Even if the fork stabilizes, that's just where the journey begins. The X.org system interacts with tons of other systems (the kernel and GPU drivers, among others), so that work need to be kept up with. At the same time, developing all of the new features the dev wants to add will be pretty useless unless applications start making use of them, and they're not going to if the project remains small.

If the anti-Wayland people unite behind this project and maintain their own X fork, there may be promise in this fork. But looking at the history, this is more likely to become another X12/Y11, or maybe a Mir if he can get a distro to back him.

My assumption is OP doesn't know much about LLMs. Clearly speaking to chatGPT as a person (which I'm guilty of as well at times), but the personification goes further, as you're assigning it attributes that it can't have. Even in the comments people are drawing comparisons to a psychopath... It's just a bot. Also, their chatGPT's response style seems to me like it's been personalized. I also hate when chatGPT hallucinates and starts giving nonsense response, but I acknowledge its just "hallucinating"; what we don't want to start doing is attributing human emotions to a machine.

> So whether it's a fat trap or any other trap the way out is always the same - willpower.

Which is completely wrong according to science on the topic. Trying to willpower your way out of addictions is a recipe for failure. It's been shown over and over again. People who are aren't addicted don't have more willpower. They have to exercise their willpower far less than someone who struggles with addiction. Identifying and eliminating environmental triggers will do far more for an addict than "willpower" will. Instead of inane advice like "just have more willpower bro" we should be teaching people about environmental triggers and how to structure your life to avoid them without relying on willpower constantly.

> you need to find a way to take care of yourself

Here's the crux of the issue; for most people who are fat, finding a way to take care of themselves is so onerous, complex, and difficult that they're not technically stuck, but they're effectively stuck. If you need to drive more than an hour to get access to food that won't be terrible for you, it's not surprising that so many people have a problem.

> How do we know when that even was? I get we can know it wasn't right at fertilization

Good. Done. Problem solved. We agree that we don't need to know exactly when it was to know when it definitely wasn't.

> Adding this dystopian layer of trying to select for the best of your offspring based on genetic hypotheses about their future

IMO you should stick with this part and forget about the embryo part. You can be worried about the process and outcomes of eugenics without focusing on any hypothetical unselected individual.

Here's one guy that posted about his short stint with DOGE, when it was still in the planning stages

https://vinay.sh/i-am-rich-and-have-no-idea-what-to-do-with-...

https://news.ycombinator.com/item?id=42579873

"When I got back home and regaled my friends with my mountain stories, one of my friends joked that I should work for Elon and Vivek at DOGE and help America get off its current crash to defaulting on its own debt. So I reached out to some people and got in. After 8 calls with people who all talked fast and sounded very autistic smart, I was added to a number of Signal groups and immediately put to work.

Working for DOGE for 4 weeks, remembering the power of urgency

Within 2 minutes of talking to the final interviewer for DOGE, he asked me if I wanted to join. I said “yes”. Then he said “cool” and I was in multiple Signal groups. I was immediately acquainted with the software, HR, and legal teams and went from 0 to 100 taking meetings and getting shit done. This was the day before Thanksgiving.

The next 4 weeks of my life consisted of 100s of calls recruiting the smartest people I’ve ever talked to, working on various projects I’m definitely not able to talk about, and learning how completely dysfunctional the government was. It was a blast.

I learned about the power of urgency and having an undeniable mission. Not by reading it somewhere. By experiencing it. I came to realize how laughable my robotics stint had been in comparison. And I started to realize that, although the mission of DOGE is extremely important, it wasn’t the most important thing I needed to focus on with urgency for myself. I needed to get back to ambiguity, focus on my insecurities, and be ok with that for a while. DOGE wasn’t going to fix that.

So, after 4 intense and intoxicating weeks, I called off my plans to move to DC and embark on a journey to save our government with some of the smartest people I’ve ever met. And I booked a 1-way ticket to Hawaii."

I don't really measure it as I tune by taste these days. I usually soak a piece of lime/lemon overnight, and sometimes I add ginger or cumumber and a generous sprinkle of salt to a big water jar. I tried some of the other minerals additives, but really didn't feel lots of added value, so defaulted to pure salt.

Crowdstrike is a recent example that comes to mind. I don't see how paying for CrowdStrike made it more secure or reliable.

I would also argue that you could take all the $$ paying for proprietary software and contribute it to people who are making the open source software, making the reliance on "free" eyeballs less of an issue.

Societal norms are the problem. We’ve normalized unhealthy food. Big business has figured hit that if they make processed/refined foods easily accessible, you will buy them. Nobody wins here except shareholders, and only those shareholders in good health who don’t have to compete to get access from doctors who are overbooked with patients who have manifested a chronic illness that is statistically correlated with the aforementioned food.

Curation and promotion, even if done by a machine (LOL, why does that matter at all?) needs to come with significant liability.

It should be possible to protect content hosting services from extensive liability while not protecting companies from the consequences of what they choose to promote and present to people. Those are two separate and very different activities that aren't even necessarily connected (you could curate and promote without hosting, and in fact this happens all the time; you can host without curating and promoting, this also happens all the time—in fact, these typically are not mixed together outside of social media companies with their damned "algorithms", as far as content from 3rd parties goes)

This is a particularly fun Jepsen report after reading their fuzzer blind spots post.

It looks like the segfaults on the JNI side would not have been protected if Rust or some other memory safe language were being used - the lack of memory safety bugs gives some decent proof that TigerBeetle's approach to Zig programming (TigerStyle iirc, lol) does what it sets out to do.

If something like that were put in place, any platforms acting as a “public square” should also be required to disable all recommendation and content surfacing features aside from search, algorithmic or otherwise.

Those recommendation features already do plenty of damage even with platforms having the ability to remove anything they like. If platforms are restricted to only removing illegal content, that damage would quickly become much greater.

I think focusing on anything solely is detrimental but focusing on exercise as an aspect is good.

- eat a bit less food

- eat food that is higher on the satiety index

- eat food that has less easily absorbed calories/less processed/etc

- build muscle to raise your resting metabolic rate slightly

- sleep well

etc

I think a bit of everything with mostly a focus on less calories will be easier to adopt than just telling people to track calories into perpetuity and feel like they're starving for a good while.

SpaceX, subsidies? No. Government contracts? Yes. Tesla subsidies, also yes.

SpaceX has actually made space cheap enough for a lot of other stuff to make sense, but without competition the profits are as big as Musk needs for R&D for his hobby of LARPing sci-fi he clearly hasn't read deeply (in this case Red Mars; in the cases of Neuralink and the SpaceX drone ships, The Culture).
