Reminds me of a C++ codebase I once had to inspect that was entirely written as if it were written in Java. With camelcase naming for everything, getters and setters for every class variable, interfaces everywhere.

As this mentions some prior art but not rCUDA ( https://en.m.wikipedia.org/wiki/RCUDA ) I'm a bit confused about what makes scuda different.

It also assumes all reads and writes are volatile. In the real world, threads can witness out-of-order execution in different threads.

In my opinion, Astron's PMT (Power Measurement Toolkit) is a much more useful tool than this, because it abstracts over Intel, AMD, and Nvidia (including Jetson): https://git.astron.nl/RD/pmt There is also a paper

Surprises me to see I'm the first comment here to say: I just use GPT4 for this. Works perfectly, even for getting the Latex source of a formula you only have a screenshot of. Probably quite the overkill in terms of energy efficiency f

In the city where I live, also in the Netherlands, we had multiple of these but all of them got converted back to normal intersections with traffic lights and it has been a huge improvement.

There was a company in the Netherlands, can't seem to find the name right now, that rented out GPU clusters as central heaters, while using the GPUs to mine crypto. I believe they went backrupt during the whole crypto crash and energy

I think they refer to Lich. From wikipedia: In fantasy fiction, a lich (/ˈlɪtʃ/;[1] from the Old English līċ, meaning "corpse") is a type of undead creature. https://en.m.wikipedia.org/wiki/Lich

Does anyone happen to know of a similar tool that can compare two codes for semantic similarity?

It's incredibly useful if you have many threads that produce a variable number of outputs. Imagine you're implementing some filtering operation on the GPU, many threads will take on a fixed workload and then produce some number of

I haven't tried WebGPU yet, is there an overall performance hit compared to direct CUDA programming? AFAIK Thrust is intended to simplify GPU programming. It could well be that for specific use cases, in particular when it is possible

Ah thanks! That's good to know.

I bought the first edition when it came out, and definitely it was a gold mine of information on the subject. I wonder though, is the fourth edition worth buying another copy? Nvidia has been advancing CUDA, in particular moving more toward

If you want to go really in-depth I can recommend GTC on demand. It's Nvidia streaming platform with videos from past GTC conferences. Tony Scuderio had a couple of videos on there called GPU memory bootcamp that are among the best adv

As a home brewer myself, I'd say it's not harder to make just more expensive.

It does. There's an overuse of graphs and especially the lack of units and y-axis labels on some of the graphs was annoying, but overall it's still a quite interesting and entertaining read in my opinion.

I live in the Netherlands. My own gas usage was 25% lower in 2022 compared to the average over 2019-2021. We didn't do anything drastic to reduce gas usage. The first 3 months of 2023 were somewhat colder with gas usage is much closer

Surely reminds me of Harry Potter and the Prisoner of Azkaban, where Harry is saved by himself as he at some point in the future travels back in time to save himself.

I always find it disappointing when people equate CS to programming. In my view, programming is a at most a means to an end in CS. A tool that we use to show that something is possible, to implement a proof of concept. By looking at the cod

I'm very unfamiliar with this family of tools, but if anyone knows a tool like this that can monitor arxiv or Google scholar for new papers matching a particular query, I'm very interested. I checked Zapier recently but I didn&#x2

Same here, I read the Readme twice and was still puzzled what this is for.

This is a great post for people who are new to optimizing GPU code. It is interesting to see that the author got this far without interchanging the innermost loop over k to the outermost loop, as is done in CUTLASS ( https://githu

I also live in the Netherlands. I confirm that the above comment very accurately describes the agriculture situation in the Netherlands, much more so than the washington post article.
