Finally getting around to digesting some of the news coming out of Computex.

The AMD announcement of die stacking an extra 192MB of L3 cache on top of the 5900X/5950X cpus and the processors coming out at the end of the year has me wowed.
Showed an actual physical implementation and gaming benchmarks of the Zen 3+ 5900X.
Although as Anandtech mentioned, the performance improvements from such huge caches are only seen in games & compression/decompression workloads.

However with them fitting more & more cores & threads on a single socket, this technology will be needed to help stop the cache sizes from getting smaller on such massively multi-core chips which would cause a significant hit in performance.


I ran into an (I think) Cache limitation on my Amd 3950x. It meant I couldn't run more than 6-8 Einstein at Home cpu Gravity Wave tasks without the processing speed taking more than 100% longer. (4-6 hours vs. 12+ hours). I thought at first it was a ram limitation but when I dropped in a 64 GB kit it still slowed down.

I miss Seti.

I wish there were other ways that I could continue to help the SETI process via computation.

Failing that I have resorted to Physics/Astronomy-based projects as well as "Socially Conscious Projects" (aka: World Community Grid).

Hi,

I like to talk with other people about BOINC projects.
I like to talk face-to-face.
I live in North East Kansas, USA

Is there anyone nearby?

Definitely a "cringe-worthy" view. And a great reminder of our collective experience in building PC's from scratch. I used to say a "trained monkey" could put a PC together after purchasing my one and only pre-built, store bought computer back in the Intel 386SX days.

Now I have a lot more respect for the monkey.


How about a trained Monkey could take a PC apart? ;)

One task at a time. You don’t want to run more than one GPUGRID task at a time as the CUDA app already uses all the compute resources it needs with 95+% GPU utilization.

This is also on Linux. The Windows apps are about 15% slower than Linux on GPUGRID


It is up and running with one task at a time. The RAC per task seems to vary all over the place.

Personally I think GPUGRID is the best choice for modern nvidia GPUs

I have a 1660 Super doing about 450,000 cred/day at 100 watts.


Is it running 1 task or more than one?

Why do you run a particular BOINC gpu project?

According to Google /Boinc, the only Boinc projects that use Nvidia GPUs are:
Collatz Conjecture (Windows and Mac OS X on Intel)
DistrRTgen (Windows, Linux 64bit)
Einstein@home (Linux, Windows and Mac OS X on Intel)
GPUgrid.net (Linux 64bit and Windows 64bit or 32bit, requires a video card with Compute Capability 1.3 (CC1.3) or higher)
Milkyway@home (Double precision GPU required, so compute capability 1.3 or higher, meaning a Geforce GTX 260 or better) (Linux 64bit and Windows)
Moo! (Driver 256.00 or better, Compute Capability 1.0 or higher, Minimum device memory 384 MB - http://moowrap.net/forum_thread.php?id=16)
PrimeGrid (Proth Prime Search (Sieve), Linux 32bit, Linux 64bit Windows and Mac OS X on Intel; Cullen/Woodall Prime Search (Sieve), Linux 32bit, Linux 64bit, Windows and Mac OS X on Intel)


And AMD/Ati:
Collatz Conjecture (Windows, Windows 64bit, Linux 64bit)
Einstein (Linux, Windows on Intel; Mac OS X under active development)
Milkyway@home (OpenCL support and Double precision GPU required, so a Radeon 48xx, 47xx, 58xx, 69xx, FirePro V87xx, FireStream 92xx) (Windows only)
Moo! (Driver v10.4 or later, ATI Runtime (not older AMD), Minimum device memory 250 MB - http://moowrap.net/forum_thread.php?id=16)
PrimeGrid (Proth Prime Search (Sieve), Linux 32bit, Linux 64bit and Windows)


Am I missing anything?

The reason I am interested in it is I have a Gtx 1660 Super that I have now mated with a 3900x CPU as my "daily driver" and I was wondering what choices I had besides E@H? While I am not sure my daily driver is going to continue to run "all the time" it is one of two machines I have Nvidia video cards on. So I am trolling for more information.

Tom M

Opps. Forgot MLC@Home which does run gpu tasks. Don't remember which brand (maybe both).

Some video cards with both display ports and hdmi ports won't display the POST Bios. Just the OS start up.

I am looking at your Rx 580 on my Amd 3950x

I am going to have to go borrow an hdmi to vga adapter from another machine and look at my bios settings again. The cpu is not running up near 3.9 like it used to.

Done

I can't figure out what Intel is doing messing about with big.LITTLE architecture for their 10nm desktop processors.

Is that their attempt at MCM to combat AMD on the desktop?

I am just thinking of all the changes to operating system schedulers that will be needed to figure out how and where to dispatch processes to appropriate nodes.

A nightmare to be sure.

Will have to wait for 2Q 2021 at least to find out.


I suspect this is part of Intel's counter-attack on the ARM cpus that are starting to X86 cpus...

Android/Kindle Fire seems to be able to cope with the BiG.liTTLe cores just fine (I think). At least the Boinc Manager on my Kindle Fire seems to notice all cores and unless I use more cores than the little ones it only runs on the littles (I think I remember).

That is what Wine and Proton are for. No need to port any apps. Just run your existing Windows apps.


I have seen reports that Wine is not able to run "everything."

I've just started "Ignition! - An informal History of Liquid Rocket Propellants" by John D. Clark.
To quote from the Preface (by Isaac Asimov)
Now its clear that anyone working with rocket fuels is outstandingly mad. I don't mean garden-variety crazy or merely raving lunatic. I mean record-shattering exponent of far-out insanity.

John D. Clark survived into retirement in a field where many didn't... and his book sort of tells the story of these chemicals which want to explode, poison, burn, or just simply kill you. And it's an easy read!!!!!

"Just" a matter of design. And deciding if they want to re-use the way tasks are being created. Some cpu designs depend heavily on a database-type approach and so can't easily gain much from the parallel processing that gpu's represent. If a CPU task is completely discrete (not needing to access data outside of the task downloaded) it should be possible to convert it to gpu processing.
