For me, it required a hard unfollow and sometimes block for anyone talking politics, softer measures for dunking/clickbait/bullshit. After that, the place is a pretty great with smart engineers talking engineering.

Indeed, one needs to give some signals (like, mute, block) to the algorithm in order for it to work.

I thought to myself this morning: "boy, that $15k pricetage is tempting." Then I thought to myself "how many times have I downloaded a github repo only to hand-replace cuda with mps, and then tried to figure out if there's a version of xformers that will work this week with my m3?" and then I thought "boy, that $25k is tempting." (15k: Radeon / 25k: Nvidia).

For those wondering, 3200W power, in residential / low-end commercial in the US, they say you'll need two separate circuits, they have a built-in power limiting utility in the OS which will let you safely run on one circuit at reduced speed.

The only part of this that gives me pause is interconnect -- over PCIe, 64GB/s stated. This is much, much lower than infiniband -- can any ML engineers comment on using this box for a full finetune of, say, LLama 3.1 / 70b?

Very unusual specs on paper. - Air cooling 6x4090 and a 32 core CPU for sustained peak workloads. - 3200W total power when a single 4090 can draw close to 600W. Maybe they are targeting startups who aren't interested in overclocking.

A 4090 draws 450W unless you unlock the power limit

Transient might be an issue. GN discuss transients of ~30/40% over the nominal 450w (https://www.youtube.com/watch?v=j9vC9NBL8zo&t=616s).

And with a distributed training you can end-up with "synchronized" transients over all cards :(.

This thing could run off a single US outlet (1600W) with some throttling, if I'm not mistaken? Shame it wasn't designed for EU sockets. 230V*16A = 3700W, or double that on separate breakers!

On their site they say it can run at 220V 15A if you got that.

If you don't use your account you will get what most people look for in your location, in your case probably sex, violence, politics, memes, ragebait...

The feed should adapt to your tastes depending on what you like, retweet or who you follow, maybe also on what you click on. You can also add topic of interest somewhere in your profile.

For me, just following a number of "good" accounts seems to do the job.

Or you could just ignore the "For You" tab and use the "Following" tab

Social media sites are the collective equivalent of a "dollar auction"[1] In the dollar auction, each immediate choice isrational, but the overall process inevitably results in you losing value once you've decided to participate. But at each step, you lose more by quitting than by keeping going. Social media is the same, except that it's collective: if you want to keep in touch with certain people, you don't have a c…

As someone who doesn't use social media this analogy strikes me as a rationalization for something you know is bad for you and a waste of your time but you can't stop so you make up this fiction about a dollar auction.

An alcoholic who can't stop going to the bar because they will lose their drinking buddies is not a dollar auction.

https://tinygrad.org/#tinybox Looks like good value, but I wonder if it would get CPU/RAM bottlenecked, especially if you want to train something with a lot of preprocessing in the pipeline. Something comparable I've found with 7x4090 which comes to about $50k, but with much better CPU/RAM (3x CPU, 4x RAM, 5x SSD): https://www.overclockers.co.uk/8pack-supernova-mk3-amd-ryzen...

> 6x PCIe 4.0 x16 (64 GB/s) Wikipedia [0] states that PCIe 4.0 x16 has a throughput of ~32GB/s, what does the (64 GB/s) indicate on the website, is this just a typo and you have 6x ~32GB/s or does it mean in total you can "only" expect a throughput of 64GB/s all lanes slots combined? If so, wouldn't you also be bottlenecked by the PCIe bandwidth (when moving data between CPU and GPU)? [0] https://en.wikipedia.org/wik…

Well they're specifying the AMD EPYC and one of the things that the server line of AMD CPUs do that the consumer grade ones don't, is they have lots of connectivity. So for example an AMD EPYC 8324P is a 32 core CPU with 96 lanes of PCI Gen 5. Given that the 4090 GPU is PCI Gen 4, I think that's where you get the discrepancy. The 6 GPUS are connected in parallel to the CPU with 6 x16 connections (96 total lanes), the CPU could do this at Gen 5 (64GBs for each GPU) but the 4090 GPU is Gen4 only, so you'll only actually get 32GBps per connection.

It’s weird how non-specific the CPU is there. Why wouldn’t they list a CPU part number? We don’t even know what generation of Epyc it is. (I get that it’s not the focus… but it is still important.)
