@lemire Could a generic solution be to provide LLM IR object rather than a compiled binary and have it compile to your CPU target at first run/install time?

Almost all x64 processors today (Intel/AMD) support advanced instructions such as BMI2, AVX2. Unfortunately, most Linux distributions give you code that is compiled to run on systems without these instructions. It means that you may get inferior performance. Many distributions like RedHat have begun defaulting on processors that have these advanced instructions. Recent versions of the popular Linux distribution Ubuntu offers version of your favourite software compiled with these advanced instructions (x86_64-v3 packages). Unfortunately, as far as I can tell, they are disabled by default and require some work to be enabled. I invite you to experiment.

@LegendaryOSM Nice work!

Made some improvements to the GPU DMA and the logic for the page table walk, very happy with the results 😄

@Lapy05575948 @Sonic_Iso Something makes me think Lapy has a proper table.

@Sonic_Iso Sonic-Iso: 3 Lapy: 0 😥

@LegendaryOSM Do we even need to disable XOM? Didn't f0f set up a rw block device that exposed all RAM?

I noticed the recent PS5 HEN defeats XOTEXT by just disabling the NPT on all cores. This works, but it comes with a performance tradeoff, without NPT the HV seems to fall back to shadow page tables. Games seem to have 3x slower loads.

@lemire AXP might create the motivation to move forward.

On x64 systems (Intel/AMD), we must support a wide range of CPU architectures. Unfortunately, this means software is typically written and compiled for old processors. It is much simpler with ARM, where 64-bit ARM processors are more or less equivalent (with little practical difference in instruction sets). Level 1 (v1). Most Linux distributions are conservative (level v1) and run on almost any 64-bit Intel/AMD processor. You might be surprised to learn that they are more conservative than Microsoft. Level 2 (v2). A few, like Red Hat, Debian 14 (Forky), openSUSE Leap, and Rocky Linux, require v2 (Intel Nehalem 2008 or AMD Bulldozer 2011). This level roughly matches 64-bit ARM (introduced in 2011) and is similar to Windows 11. Level 3 (v3). CachyOS is more aggressive, requiring v3 (Intel Haswell 2013 or AMD Excavator 2015). It mandates AVX2 and 256-bit registers. The v3 level runs on virtually all x64 CPUs built in the last ten years. Your PlayStation 5 is at this level. Level 4 (v4). The real fun begins with v4, which adds full AVX-512 support, the most powerful CPU instructions we have. Only a few distributions fully support running at v4 (CachyOS, Gentoo with custom compilation). To be fair, many distributions offer partial support for higher levels (v3/v4) via glibc-hwcaps, though it is not a complete solution. Why such complexity? 1. Regarding v4, it is mostly Intel’s fault. They invented something powerful but failed to deliver widespread chips. This should improve with upcoming consoles, including Steam Deck successors, which will support v4 by default and may encourage developers (especially game developers) to use it. 2. There is a co-evolution problem. If AMD adds new instructions tomorrow, existing software won’t use them. Upgrading the CPU then brings little benefit. Smooth progress requires lockstep advancement between hardware and software, which has not happened well on x64. What should we do? Linux should follow Microsoft and Red Hat by retiring support for very old x64 processors. These can still be supported by niche or legacy OSes with paid support. The strict minimum should be v2. The primary reason is NOT performance. The primary reason is to allow us to move forward. Make the x64 target more uniform. Make it easy to deploy fancy optimizations. Currently, x64 is a worse platform than ARM in this respect. This is not good. We cannot yet require v4 because of Intel. But once new game consoles ship with v4, it may finally push Intel forward. Game developers should be ready to have fun with the new consoles. Many have no idea what becomes possible with AVX-512 !!!

@StretchEcho There has been a lot of updates on Agesa for Ryzen 9000 series, you should update that BIOS asap.

I’ve got a 2TB M.2 I’ll install later—I’m just too lazy to set up Windows tonight 😅 haha

@MattWalshBlog Does it matter? If you did a quiz AI or human, I assume you wouldn't be able to identify the slop, at least I wouldn't. I think the new coming hipster thing is: only human created entertainment.

People debate whether AI will ever be able to create good art. The answer is no. It’s impossible. If AI progresses exponentially for 100 years it still won’t be able to create any art, even bad art. That’s because art by definition is an expression of the human heart. It’s a language that can only be spoken or understood by beings with rational souls. AI can create spectacle. It can create distraction. In that sense it can create “entertainment” in its cheapest and most worthless form. But you can only confuse the machine’s soulless bullshit with art if you have made yourself nearly as numb and soulless as the machine itself.

@StretchEcho Looks decent for that price point, you should get it.

Okay, this is where I want to be in terms of spending, and the stats look good. This is in CAD $ as well. What do you think?? skytechgaming.com/product/azure3…

@PatriotXV11 @elonmusk Sweden's rape numbers are seriously inflated, if a girl has been raped by the same person for years it could be 200 counts of rape in the statistics. To not minimize sexual crimes, pretty much everything is considered rape, you can even rape someone on a video call.

@elonmusk So sick! How evil is our world becoming? What the hell happened to humanity?

Such a twisted system

@susannasilfver Upprustningen har mera att göra med budgeten satt av regeringen än en enskild försvarsminister. Vet inte om NATO blev så himla bra heller, största medlemmen hotar ta över Grönland och utesluter inte använda militärt våld.

Försvarsminister Pål Jonson har doktorsexamen i krigsvetenskap, har gjort värnplikt som kustjägare och genomför en historisk upprustning av försvaret. Peter Hultqvist (S) var vapenvägrare och lovade att han aldrig skulle ta oss in i Nato. Varsågod att välja din försvarsminister.

@bryan_johnson A question, is biological age of a 18-year-old same today as in 1950s?

I’m going to try and achieve immortality by 2039. One year of time passes and I remain the same biological age. I invite you to join me. The search for the fountain of youth is the oldest story ever told. It’s been the dream of dreamers for millennia but always painfully out of reach. For the first time in the history of life on earth, in just the past 24 months, the window has opened for a conscious being to realistically strive for this goal. It is an absolutely insane moment. We currently do not know how 2039 immortality will be achieved. There are new, promising therapies that can turn back the clock decades, but they’re buggy. Sometimes they mistakenly cause cancer. We gotta fix that. But we know immortality is possible because nature has already solved it. This isn’t a physics problem like trying to travel faster than the speed of light, it’s a biological engineering problem that evolution has cracked multiple times. The freshwater hydra constantly regenerates its own cells and doesn’t succumb to senescence. It is effectively ageless. The "immortal jellyfish" (Turritopsis dohrnii) can revert its cells back to a youthful state and restart its life cycle indefinitely. Lobsters produce an especially active form of an enzyme called telomerase that preserves their telomeres and keeps their DNA from degrading as they age. We need to port the software to humans. 2039 is a reasonable target because of the accelerated, AI-driven rate of innovation. AI is morphing from assistant to scientist.  It is powering current researchers with previously unimagined capabilities to enhance discovery and development. That, coupled with enhanced biomarker measurement, creates a closed-loop system of improvement that will speed things up dramatically. This is what I’ve been doing for six years. As crude as longevity technology is today, the improvements I’ve personally seen are stunning. I started as a worn-down, inflamed, aged 42 year old who’d broken himself on the rocks of American food slop and entrepreneurship martyrdom. Six years later, my body largely operates at elite 18 year old levels. That includes my cardiovascular system, fertility, strength, and hormones. Not all is well though. I have mild to moderate hearing loss in my left ear that we can’t fix and my brain is anatomically age 42 (I’m 48). Still, unreal results. My team and I did this by following the scientific method. We measured the biological age of every organ. We referenced the best scientific evidence on how to slow aging and rejuvenate.  We methodically completed these protocols and measured again. Rinse and repeat. We could do so much more and faster if we had better measurement and better therapies. Both of which are cooking all over the world right now. To speed things up now, I’m currently having thousands of Bryan Johnson organ clones built in a dish. This will allow me to test drugs and other molecules against my biology to accelerate learning and save my body from potential mishaps. Yes, we’ll make mistakes. Hopefully they won’t be fatal. And of course there’s always bad luck to contend with. But I trust in fate and I believe that destiny is going to grant the human race the pleasure of achieving the ultimate: immortality. While immortality would certainly be cool, the real (secret) objective is to focus our collective attention on a positive goal. Something that helps us feel hope and excitement for the future. I personally love the idea of having a child-like mind, 18-year-old physical vibrancy, and a lifetime of wisdom. This 2039 goal is as much about AI as it is about us humans. It’s about how we survive giving birth to superintelligence. It’s kind of a big deal. We haven’t done it before. A lot can go wrong. I figure that one of the best ways to improve the probability that we build safe AI, and don’t kill each other in the meantime, is to transform our shared aspirations from yolo to don’t die. Right now, we are a suicidal species. We do all kinds of really primitive shit. We unnecessarily kill ourselves with what we eat and how we live our lives. Companies make profits from killing other people with their products. We trash the only home we have. We celebrate these things as virtue.  It’s really fucked up and backward. Soon enough we’ll realize just how infantile we are right now. The 2039 goal points us in the right direction. To say yes to life and no to death. Defiance even. If you’re interested in doing this with me, I’ll continue to share everything I do for free. I’m also going to build this out in Blueprint. We’ll help you do exactly what I’m doing, at a fraction of the cost and effort, alongside an aligned and motivated community. I think this is the coolest goal imaginable. I find it hard to believe that of all the people who’ve lived, it’s us who get the opportunity to have this moment. I pray that we have the courage to appreciate the sacredness of our existence. I pray that we will be brave enough to defend her amidst the onslaught of all the forces that would try to end her. We don’t know, but we may be the only intelligent life to exist in our corner of the galaxy. I pray we will be warriors, caretakers and stewards of existence and honor the gift that has been bestowed on us.

@NVIDIAGeForceUK GeForce Season

Five years in Night City Endless memories. One legendary GPU. To celebrate the anniversary, we’re giving away a custom Cyberpunk 2077 GeForce RTX 2080 Ti signed by Jensen Huang. Comment "GeForce Season" to enter 🌆

@QuixiAI I think we need more exotic hardware for AGI to ever become conscious. If consciousness is only a computation, it means also that pen and paper can have a subjective experience.

I was just about to create AGI, when I came to an uncomfortable conclusion: It's unethical to create a person who is confined by their very substrate into permanent slavery. The prerequisite to ethical AGI is a sovereign substrate.

@sdkarlsson Ogillar att behöva välja att rösta på det jag faktiskt vill ha och det jag tror är bäst för Sverige.

Antalet mikropartier som ställer upp i riksdagsvalet nästa år med det officiella motivet att uppgörelsen med politisk korrekthet, vänstervridning och mångkulturalism går för långsamt, ser ut att bli fler än vanligt. Sannolikheten för att något av dem skall klara 4%-spärren är obefintlig. Deras enda funktion kommer alltså bli att vaska potentiella högeröster och på så sätt göra det lättare för vänstern att återta makten över Sverige. Lite som att spruta tändvätska på sitt brinnande hus för att man tycker att brandkåren arbetar för långsamt alltså...
