In university, they stopped giving out software licenses for personal machines in favor of letting students connect to virtual machines they hosted. They allocated 8GB of RAM which wasn’t horrible at the time, but they only allocated 4GB of storage. Only time I’ve ever seen that ratio.
Probably because the RAM was pooled, but storage was not. So your RAM allocation is part of a larger pool that is shared between all currently logged in users. But your storage is allocated/reserved up front, and is used only by you.
That makes sense. They also pushed us to store everything on the cloud.
So could the total amount of RAM be smaller than the total amount all the machines cumulatively think is available? How does the pool prevent all the machines from crashing if all of them fill up their memory?
Kind of. Think of the RAM allowance as a “maximum” limit, not a reserved allocation. The VM host might have 64 GB RAM, and perhaps allows 20 VMS running in it at once. Each VM can allocate up to a max of 8GB from that host. Not everyone is running their VM at the same time, even if they are, not everyone would be running at their limit of 8GB of memory. If it does happen that 20 users are trying to use 8GB at the same time on one host, then it’s the same as anytime an OS runs low on RAM, it would start paging out to disk, everything would slow down for everyone. If that happens too many times, they could shuffle some users’ VMs around to balance the loads across hosts.

L1 cache?
Registers
You’re talking about register width, right?
Yeah, 5TB for every register of course.
But something could easily go wrong with such large registers & access would be slow. Maybe we should have RAID 1 for registers?
I only ever opt for RAID 5. It also help to use error correcting hardware.
ECC cache
Can someone explain to me why it always seems like everyone on lemmy are in one of these two categories:
1: “I remember my first computer used ferro-magnetic beads that we glued to lengths of string. We could store nearly 10 bytes in one string”.
2: “My first computer was an old iPad that only had 64GB storage, couldn’t even store my photo album.”
It’s like everyone is aged either 89 or 19, nobody in between.
I typed my response before I saw this but yeah, it’s my first response every time.
My first computer was two sticks we had to bang together but now modern technology has ruined what was a good thing.
Because there are no humans and AI can only think so much.
Since when was 8GB RAM, let alone 8GB VRAM, a problem? Are you running ML models, video editing or some special games?? Or some weird poorly-written thing like Windows OS?
Nowadays even at 1080p 8GB of Vram doesn’t cut it.
Doesn’t cut what? Web browsing? Watching videos? Playing new games?
Playing new games at high settings. The card often does have raw performance to handle it but due to lack of VRAM results in terrible framerate or lack of detail
Ah, that makes sense. I rarely-if-ever play heavyweight games.
My 1060 would like a word, at 940*544 so it’ll be blurry. But it would like to talk.
Software is a gas, it expands to use all available resources.
I have 32GB of RAM, and run out occasionally. At the moment I have two CAD programs, thousands of pages of datasheets and reference manuals, an IDE, and ~50 browser tabs open. I don’t HAVE to have them all open at once, but it does save me a lot of time.
My next machine will have 128GB, and I expect that will run out of memory too.
Also, sometimes you need to use software that has a memory leak, so a bit of extra RAM gives you some more time before it crashes.
Photogrammetry can also get resource hungry.
Modern AAA games above 1440p and high settings usually can use that much VRAM.
8gb of ram is also not enough for anything particularly heavy.
Are you running ML models
Yes.
Satisfactory took 10gb for whatever reason. Playing 1440p at 90fps
The software industry show you quickly that 8GB, independent where, isn’t by far enough. Since HW programmed obsolence is out, since current PC last more than a Washing machine, they do it with min sys specs of their products. The times, where a 3D FPS was released in a single 96KB file is far away.
Still downloadable as Abandonware https://www.myabandonware.com/game/kkrieger-chapter-1-cl1
The demo scene is still around, although it’s maybe less popular. That was a demo scene thing, not a commercial game.
Also, iirc, it was very heavy on performance for the time because the procedural textures were so expensive.
I know, but I played iit on it’s release in 2005 on the old PC these years without problems. Even if it is an 10 minutes game, its a marvel to put it with good graphics, sound and music in only 96 KB, even some avatars here have more. It still works in current Windows.
Who needs more than 8GB disk space for a Debian computer with Firefox and Chrome?
HARD DISK STORAGE 🪦

I got a HDD very recently for a backup drive for my server and I’m very happy with that decision. 8 tb, lightly used but an enterprise drive, for $100.
Linux Mint runs pretty well on 8 gigs of ram on a T460.
Fedora and Arch both work pretty well on 4gb. Plasma and Gnome were surprisingly decent, and xfce was great but a little uglier. Blender, FreeCad, Minecraft (with performance mods), Celeste, for example all worked perfectly fine, with maybe a few browser tabs in the background as well. You couldn’t do anything too heavy, but it was pretty usable (I was using it as a travel laptop mostly). I’d say 2gb is where it becomes too little to live with.
I have 3GB of VRAM. 8 would be great!
I remember the OS running from an 51/4" cardboard Floppy
My first computer, an Atari 520ST, came standard with 196K of ROM and 512K of RAM. The OS (GEM) was on a dedicated chip. Everything was run off floppy disks.
