GPU Compute / Accelerators / Re: AMD GPU at boot

I'll be doing some comparison between the 3990X and my dual Power9 running our custom texture compression code. I'll not get around to it for a while though. The code scales quite well with more cores but eventually becomes memory bound. Our 3990X machines here are all overclocked and hand tuned, so I think it'll be a tough one to beat.

Temps seem normal, hovering around 50C. Running stress-ng for a few mins the hottest parts are the VRMs (60C).

I currently have the HSFs but I'm working on a water cooling solution for it (which I'll report back on once it's finished). We do custom 3D engines and tooling at work and I was looking into alternatives to our current Threadripper setups for texture processing. It's a highly parallel task that benefits from many threads, currently running best on the 64C/128T 3990X, but I was curious as to what else is out there.

I've not had much time to experiment so far, and it'll be at least a month before I get some quality time with this machine.

Thanks, I'll check tomorrow (I'm assuming being a brand new mobo it wouldn't have the v1.0 firmware, but in any case I'll look at this).

Where can I find info like this, or does everyone just know and I'm late to the party? The quick start guide seems to trail off when it should just be getting started, but I did (just now) find the other guides and I'll look through them (in particular adding the GPU firmware).

GPU Compute / Accelerators / AMD GPU at boot

Before typing I'm already feeling the burning shame of a n00b question, but anyway, here goes...

I finally built my Talos II (dual 18-core), temporarily installed a Radeon RX 580 (I plan on a Radeon Pro W5700 but it currently has a waterblock fitted) and installed Ubuntu 21.10 (server install followed by desktop packages). It's early days and it's mostly working (Firefox 96 has issues, but one thing at a time). So far so good. I've disabled the built-in VGA via the jumper but it still starts up with this and then hands over to the Radeon card. Is this normal?

See the attached image.

These are 18-core chips. I didn't see anything when fitting the chip, only on the photo.

I have spare indium pads, since I'll be going the water-cooling route eventually and expected I wouldn't be able to reuse them.

I've not powered it up yet, should do either tomorrow or next week. I guess I'll see with the temps!

Talos II / Film on Power9 CPU?

« on: January 27, 2022, 06:28:39 am »

I took some photos whilst building up my system and it's only on looking at the photos I noticed what appears to be a film on the CPUs?

I could take the heatsink back off and take a look a guess but wasn't sure the indium pad would still be good after doing so (or can I remove/refit the cooler as often as I like?).

Is it a trick of the light, my imagination, or is there a film that needs removing?

Thanks for the update. I'm surprised no-one has a working version, but I guess OpenCL/CUDA support is on Nvidia A100 and other server-class cards.

Thanks - good to know for the W5500. My mobo and CPUs arrived last week and I should have the time soon to start looking at this.

Any update on this? OpenCL is on my list of things I'd like to have working.

I have spare RX580 and W5700 cards to try with. And for the full PPC Nvidia experience I have a Quadro FX4500 from a Quad G5, but I'll stick with the AMD cards!

Mod Zone / 2U or 3U Heatsink Assembly Wanted

« on: December 21, 2021, 12:08:00 pm »

I'm looking to buy a 2U or 3U heatsink assembly to sacrifice for building a waterblock, does anyone have one for sale? I'm central Europe so would prefer to buy something already over this side of the Atlantic (not for jingoistic reasons, just that it's less hassle for import duty and taxes).

I already have a couple of 3U HSFs arriving with my system (any day now!) but I'd like something to dismantle and measure.

VSCode with native compiler integration, step debugging, etc.?
