Why can't you lazy bums just shave with a razor? Is it really so much
trouble to just drag a piece of metal across your face?
Real men have their horses kiss their beard off (because a horse's idea of a kiss involves intensive use of teeth).

Real men dont shave :)
Exactly. They have the horses do it for them XD :P
Now seriously, when I shave I confuse my horses. They try to grab my beard and get sad because it is not there.
Incidentaly, I have a picture of one of my darlings as a desktop wallpaper here and you made me miss them all so much.
Man, wish i had a couple of A100s....
What's an A100? A search says maybe it's a graphics card? Or a van from the 1970's :)
Oh, I see ... people are using Nvidia A100 as high-density compute for "AI" workloads.
I have to admit I don't really understand the whole "compute on GPU" thing.
What is it about a graphics coprocessor that couldn't be done better by some sort of high-density main CPU?
Tho i have called them video cards a few times, technically they are not. No video ports or support to produce video. Only GPU.
Found some lower end referb 24gb titans for a really decent price.. but i dont think my motherboard can handle them, and im not going to start spending more on motherboards and stuff too. hobby is not worth that much to me.. Already spent more than i should have.
Reason it works so well is not that its a 'graphics processor' its a parallel targeted compute module that does math really fast, on several thousand cores. Just happens to also do well for computing graphics too, so was used in them traditionally.. It wont do well with general stuff and moving bits around, but just doing general math, yes.
Quick comparison of what i have, running for stable diffusion ( images )
- Xeon 12 core. Takes 35 minutes.
- Add a 4gb video card to the mix and it drops it to 3 minutes
- Swapped it out with an older 12gb video card. Now its 15 seconds.

unsure the details yet but a friend of mine just came home with 3 fairly new 3D printers "i found these in the trash"
That is like stories of people seeing Altairs and such on the curb for trash day.. i never see stuff like that.

In the desktop hosting (VDI) world there are setups that can use a GPU in the server to accelerate the remote client's display. I think it can even be shared between multiple users. As far as I can tell it only supports a small number of specific GPU types, so I guess they're not just making OpenGL or DirectX calls the way a single-user operating system would.
So the GPU is essentially a massively parallel compute unit optimized for calculations but without all the trimmings and trappings of a general purpose CPU? That sounds like ... something other than what the end state will be.
Yup

So a Xeon E3-1275LV3 is not the same as a Xeon E3-1275 E3
Sigh. Burn $ like it comes on trees.
( but to be honest. i thought it said the same i guess i cant rea.. now i have a useless, to me, cpu in a drawer )
and i ordered the wrong power transformer for something.. ( amazon, 'order another' button but forgot i had ordered a similar one for an odd-ball case that was NOT the same plug.. )
geesh. not that either were enough money to really care about, its just frustrating..
And then you have shoes... 'driving moc' show up as 'steel toe work boots'. Wrong leather too so assumed just a total mistake, send it back, order anther. Check status " work boots" again.. wtf.. the 'store' does not list them correctly.. ( tho the 2nd pair did have the correct leather.. but no, i cant wear steel toe even if i wanted to )
( ya borderline rant.. but it was related to the CPU thread.. no pun intended :) )
Well that F-ed up ARM board i had waited on for a year to arrive.. it made a round trip from here to china and back in under a month.
They replaced the defective power IC. Booted first attempt. Frustrating. But, its working now.
Decided to finally upgrade my desktop from an old Xeon E3-1275L v3 to a I7 1260P. ( still lower power requirements. no need to burn electricity considering i'm not a gamer. and my Stable Diffusion box burns enough power as it is ) Will be here in a week or 2... I do hope i see a difference and didnt just burn the cash.
I almost sprung for an I9.. but i try not to go overboard normally, and i like to conserve energy. Not that im turning green on you all.. but means it runs cooler, so lasts longer and less power $$.
( and im still annoyed from losing $ on that Tesla GPU for the AI server.. grr )
Well this is a new one.
New PC.
Runs fine for a while, ( random time, doing same thing, so not heat related ) then 'freezes', but doesn't. The running process to install freezes, but desktop isn't frozen. Can still launch a 2nd tab in the terminal emulator. Cant launch a new application in it as it freezes after you type, or use the menu... Really weird.
Im hoping its slower ram. Bought a barebone as i have ram and drives out my ears. Seems i have DDR4 2400 ram, it wants 3200... I hope that is all it is. Send it back is an expensive pain in the neck.
I have seen processes freeze before, and of course total system freezes but never this strangeness.
If I had to put money on it, sounds like you can't create new processes once you're in this state. Maybe forks are failing because the kernel can't page in more mwmory for some reason?
Experimenting some more, it may actually be the Ethernet port. I shoved in one of my 'headless auto server installers' and didnt bother putting in keyboard or lan. It installed. Have it now running memtest off that install, its been running for 30 mins straight. no errors, no freeze, cpu temp is fine.
Going to dig out a full install ISO and keep the cord out once im done in the kitchen ( gotta make the bread :) ). See if that works.
*IF* that is the problem i can live with WiFi for its intended use.
Sun Jun 04 2023 02:34:22 PM EDT from zelgomerFor stuff like that I have used Linux's netconsole to send kernel messages to another machine. Just use netcat to receive on the appropriate UDP port, and now you get to see what sort of fire and mayhem the kernel is complaining about while your local machine is frozen (or half frozen and dying a horrible death, by the sound of it).

Nope not that either. its a kernel issue. Going back to 5x seems to have fixed it. ( tried a usbC network. crash.. so it clearly wasn't drivers or the network hardware )
Ran across a few post with similar issues after i backdated the install just to see what it would do and there are some parameters to be passed via grub that might fix it for 6.x Will have to try that tomorow.
Today I'm thinking about old and new architectures, for no particular reason.
I learned that "virtual 8086 mode" was discontinued on the AMD64 architecture when running in 64-bit long mode. It has not been discontinued, however, when the chip is running in 32-bit protected mode. As we know, the virtual 8086 mode was added to the 80386 by Intel as a crutch to help newer operating systems run MS-DOS applications. It's their earliest form of hardware virtualization, really.
The absence of this feature in 64-bit long mode is likely to be why support for not only MS-DOS applications, but also Win16 applications, was discontinued on 64-bit Windows. Meanwhile, other operating systems start up in one mode and stay there.
I'd like to see AMD and Intel get more aggressive about dropping some backward compatibility. You can run 16-bit software and 32-bit software on virtual machines. As long as those modes are still supported in virtualized guests, all processors going forward should boot in 64-bit mode and stay there. That means no legacy BIOS support, no booting 16-bit or 32-bit operating systems onto the bare metal, and you can get rid of a few million transistors.
It's time. Do it.
the future is GPU/TPU/NPU
CPU will just end up being a dumb traffic cop and it wont matter what it is, or what it runs.
