Does this mean graphics workloads using Vulkan can be isolated and share most GPUs securely?
If malicious program has access to GPU directly or via some buggy interface, the whole system is at risk. There is no "safe" GPU virtualization like there is with CPUs.

I use libvirt for qemu, because I got tired of rewriting my command line every two days because the options changed yet again.
Yeah, why do they change options so often. They should keep some backward compatibility, qemu is not a new project.
> The problem it solved would take a septillion years to do on a conventional computer
And more importantly, the solution is not actually verified in any way. It might be wrong.
I don't understand (as a complete laymen) why the milestone isn't something classically hard but easily verified (in line with you). I feel like it's weird because people have spent a lot of time telling me how trivially quantum computing will break encryption that defeats normal computers.
> why the milestone isn't something classically hard but easily verified
They're far from being able to do any such thing, so posing such milestone would make the field look stagnant and thus be a bad marketing and hurt the money stream. The "milestones" are chosen so that they are plausibly reachable in short time relevant to patrons/investors, because people working on this need to constantly demonstrate progress.

What does this mean?

Europe is just getting adjusted to the new reality and the reality is not black-and-white.
Russians didn't discover magic words that they use to hypnotise people and make them vote for pro-Russia candidate. In fact, everywhere in the world the incumbent politics are losing ground because the system is in crisis and people are looking for a change everywhere and Russia appears to be able to propel politicians who are closer to the their politics simply because the incumbent ones screwed up.
Is America different? Just a month ago in the American election – those who are anti-establishment and pro-Russian won.
US and Europe will go through a soul searching and hopefully will come out of this in a better shape. It has to go through this because the ideology collapsed, economy doesn't perform and the hypocrisy is unbearable anymore.
For example, can you tell me if EU is about saving the environment and stopping climate change? If so why they are blocking the Chinese electric cars? Can't stand others making the world better place better than they do?
Can you tell me if US is about freedom and respect of the international law, borders and trande? If so why they support Ukraine against Russian invasion and then support Israel who occupies Palestinian territories since many years?
Can you tell me why people should drink from paper straws when the rich fly private jets?
Can you tell me why the capital can go anywhere but people should be stopped at the borders?
Can you tell me how the economy is s great when so many people suffer?
The west is in crisis, the ideology doesn't hold and the economy doesn't provide and all the Russians have to do is to point it out. They don't use spell, they just tell what everyone sees. This needs to get fixed, let's hope that the damage wouldn't be too big.
> the ideology collapsed, economy doesn't perform
Economy doesn't perform, but ideology has collapsed only in minds of ordinary people. Politicians, stakeholders and various media outlets are very much invested, and still push that the current course is the only correct way and the bright green future as designed is unstoppable. Reminds me of the arrogance of the ruling party slogans from before 90s.
"old aspirations"
"there is not much money in it"?
WTF?
There is not much money in it for Intel.
Intel tried to get into GPU-like products 14 years ago. They promote their consumer Arc GPUs since 2022, and still almost nobody wants them. Is there a datacenter Intel GPU that some business wants?
The big money is flowing NVIDIA's way, and even if Intel can make a GPU, it won't be able to divert a big part of the flow, similarly to AMD.
> maybe memory/solid state drives
That's a very low margin and cyclical market since memory/SSDs are basically commodities. I don't think Intel would have any chance surviving in such a market they just have way to much bloat/R&D spending. Which is not a bad thing as long as you can produce better than products than the competition.
Yeah, but they can saturate fabs and provide income, which they need. Intel can't produce better CPU/GPU products than their competition now. Their design and manufacturing of CPUs has serious problems for years now. The big money in GPUs is already captured by NVIDIA, and it's hard to see how Intel can challenge that - people want NVIDIA and CUDA. So Intel should cut down and focus the remaining bloat and R&D spending on the areas where it's plausible they can get competitive in a reasonable time. That is CPUs, and maybe memory and SSDs - they have X-Point which was great, just marketed and priced wrong.
What's the alternative?
I think it's the right call since there isn't much competition in GPU industry anyway. Sure, Intel is far behind. But they need to start somewhere in order to break ground.
Strictly speaking strategically, my intuition is that they will learn from this, course correct and then would start making progress.
The idea of another competitive GPU manufacturer is nice. But it is hard to bring into existence. Intel is not in a position to invest lots of money and sustained effort into products for which the market is captured and controlled by a much bigger and more competent company on top of its game. Not even AMD can get more market share, and they are much more competent in the GPU technology. Unless NVIDIA and AMD make serious mistakes, Intel GPUs will remain a 3rd rate product.
> "They need to start somewhere in order to break ground"
Intel has big problems and it's not clear they should occupy themselves with this. They should stabilize, and the most plausible way to do that is to cut the weak parts, and get back to what they were good at - performant secure x86_64 CPUs, maybe some new innovative CPUs with low consumption, maybe memory/solid state drives.
Too late, and it has a bad rep. This effort from Intel to sell discrete GPUs is just inertia from old aspirations, won't really help noticeably to save it, as there is not much money in it. Most probably the whole Intel ARC effort will be mothballed, and probably many more will.
