Does anyone have access to Epyc 7773x for a quick benchmark?

Does anyone have access to Epyc 7773x with at least 512Gb of RAM to test a specific workload?

7773x are now available relatively cheap on Ebay and I am trying to understand if AMD 3D Vcache is beneficial for my specific task and if it is worth it to replace my 7713P.

The test would only take 15 minutes most and it’s opensource from GitHub.

Link and deets?

Usage would be:

./bladebit --threads 64 --count 5 --farmer-key ad65cab5777776b47a54cc2947e2089c8743d0374dcbca44ed98baee55d045fd2a1c9a7b4fd6dfdd71701648bfd67340 --pool-key 8f4b9db4409333ece47f2024e33946d6d312cc0207b704aae63f2fa38eecf0fb8dc658a9fdd41ff1bcf6aa9bda016fb9 --verbose ramplot <output_directory>

This command will create 5 plots - I need average time.

Thank you very much!

Edit: Also I need the version of OS used - to replicate it on my 7713 for the clearest comparison.

Hey Wendell! Will you be able to run it?
You are my only hope to not risk wasting 5 grands!

Working on this later todsy

Thank you very much!
It’s two minutes per plot SLOWER than 7713p - something I absolutely did not expect! What memory is used on the system? Is it PC3200?

I read the process is severally memory bound, so I had hopes large cache may help.

Also may I post it on Chia community forum?

If I’m reading that correctly, it’s about 7 mins per plot? I think bladebit is a memory plotter too.

pc3200 yes, though it was with a slow ssd. I wasn’t 100% sure if it was disk plotting vs memory plotting.

I didn’t explicitly set the performance governor, re-running in “performance” mode

It definitely is memory plotting according to log and key memplot is used. Apparently 7773X just sucks for plotting…
By the way Wendell if you ever have time - please try it on new Epycs! Just change --threads parameter to core count. Garold (bladebit author) says the plotter is memory bus bound above ~40 cores on Epyc Milan, so the idea was large cache would help, but somehow it didn’t. New Epycs have DDR5 - so we might see some interesting results. Especially taht 32 cores high speed piece with additional interlink chanel to io die.

Ok stand by

this is AMD EPYC 9374F 32-Core Processor x2

should I have run the other with 128 threads instead of 64? it was a 2x 7773 system.

3,6 minutes is absolute record, but at least on Milan generation two CPU systems are only 25% fast then single CPU. Could you run single 9374F with 32 threads? I suspect it will be only marginally slower.

ok, underway. though that suggests some architectural issue in software as I can get near 2x scaling with every other multithread process across 2 socket systems w/milan in any core count config

Probably.

Also about this:

Finished Phase 1 in 134.93 seconds

When Phase 1 can be done under 30 seconds - in theory Chia can be turned to proof of work because you can generate a plot that alway passes 1/512 filter - and actually only phase 1 matters - the rest is just compression. So in theory 4 times faster system than what you have now can be a substitute of 51 Tb os space. Not that I thing it can be remotely economical at this stage, but the day when they will have to increase minimum plot size and force everyone to replot is probably no more than 2 CPU generations apart. May be earlier if HBM on chip will be big enough to fit one table. Waiting impatiently new HBM Xeons!

Waiting for l

Thnx! So roughly a bit cheaper 32 core Genoa does 1 minute faster than 64 core Milan.

will try the 96 core in a few days. I am 95% sure that if I create some hard partitions or pin processes, that I could get 1.8x-1.9x scaling of this figure by doing two jobs in parallel, one per socket and say (everything spawned from this command pin to socket 0/ from this command pin to socket 1)
and it would be close to 2x scaling
