It obviously isn't as safe as Rust, but I think it works well enough for something like gamedev(where absolute safety isn't required). For memory related issues I find it sufficient. One aspect where it is probably not as good as

It works with arrays if you stick with std::array & std::span like constructs. It also works with iterators-generally by sticking some extra data in the iterator in dev builds, so it can check for out of bounds access. If I do have some

That is the same approach used in many C++ projects

Most interviews I've done in my software career were done on more than 24 hours without sleep. Not by choice, but because I cannot sleep the night before an interview. I have difficulty sleeping in general, and the anxiety of an inter

SYSCL might be an option, but it doesn't seem to have much in the way of adoption(Forum is dead)which is concerning. It does look like Intel is supporting at least, so maybe in the future it will be a good option.

It looks good but without Intel iGPU support I don't think any gamedevs would use it :/ I wish all the GPU companies would get together and make a standard based on C++ and stick with it.

It has been publicly available since years ago(I remember reading the specification explaining how it worked), it was never a surprise like Cloudflare made it out to be.

If you write SoA code, know what are you doing, and aren't memory bound, 100% speedup isn't unreasonable. Current AVX512 implementations might not always get there, as I believe some instructions are dual issuing at 256bit under

The throttling will surely be reduced when Intel gets its process issues resolved(7nm), which is probably around when they finally ship AVX512 on desktop.

He likely has ~zero hands on experience with SIMD or AVX512 as those aren't used in his precious kernel.

You do understand that much of the news you read about the US is wildly exaggerated? Having traveled and met various young Europeans they were often suffering from amazingly ignorant ideas about life in the US(particularly the Germans). One

None of those are both portable and widely available on end user machines, which is needed for games CUDA seems nice, but being Nvidia only makes it a total dead end.

They wouldn't notice AVX512 vanishing because they never had it in the first place, as Intel hasn't shipped it in CPU people actually use for those tasks--just servers and random laptops. As for the rest, you are wrong, AVX/

GPU programming is easy enough, the complexity comes from the seperate memory system and the tedious(and not portable) API you need to use to access the GPU. I prefer intrinsics as they give more control than shader languages and they can

What are you talking about? Fugaku is the opposite of that, each CPU chip is 48 cores with 512 bit wide SVE(arm version of AVX512). They deliberately went for something easier to program, that didn't require doing the CPU/GPU dan

If Intel had their shit together they would have released AVX512 years ago with Skylake desktop, but they prefer to artificially segment the market, and have still not managed to release a desktop chip with AVX512--allowing AMD to catch up

In logic it is considered a logical fallacy to attack the speaker rather than the message. It generally indicates that you don't have a rational refute to the argument.

I think the opposite is where things need to go. Having a wide SIMD ALU quickly accessible from your CPU core is very useful, especially as it shares the same memory system and a much more flexible programming model that allows you to do e

I read the Broken Earth trilogy a few years ago-- didn't remember it had won the Hugo award for all 3 books, and don't really understand why it would have won, unless that was a particularly weak couple of year? It is a moderatel

It sounded interesting until I saw that the only float type it supports is Brain float :(

There is a future mission planned to Titan called Dragonfly, it will send a rotorcraft to the surface. Perhaps they can use the data from this mars copter to improve the odds of success with Dragonfly.

It isn't work ethic, the difference for me between full night sleep and 6 hours is night and day-- my memory barely works if I have 6 hours, doesn't matter how hard I want it to work, I simply cannot recall words for things that

I'm totally baffled by people claiming to be able to function with less than 8 hours of sleep. Even 1 night of 6 hours is enough to reduce my mental capabilities immensely. It is like a fog closes on my mind. Memory suffers particular
