[Max] Bug Reporting / Another :) Corona not using all threads topic
« on: 2023-08-06, 00:42:29 »
Hello all :)
I have a strange issue with my render node.
I'm using Pulze Render Manager to send the scenes from my WS to the Node for rendering so that I can have the WS free for work.
In some of the scenes that I send over to the Epyc node with the Render Manager (most of the time I'm using Pulze RM, but from time to time I tend to use Backburner as well), I can really see the swift render times (Corona using all cores at 100%), while in some cases the CPU usage drops only to one CPU or it's still using both CPUs but not all the cores, OR (this is the most frequent issue), it is using all the cores but the performance is jumping from 0% to 100% every few seconds and there is an idle drop between the peaks, so the performance graph is looking like a hair comb. Priority is set to normal although I have tried changing it to High and above but it seems that nothing helps.
Some scenes render really really fast (around 10-15 minutes for 4K render to finish at 3% noise threshold), while some (usually) simple scenes, take 30-45 minutes to render in 4K resolution on the Epyc node, while on my WS which has 8 times fewer threads, they render even faster.
When rendering on my WS (Ryzen 5950x, Win 11 Pro, 128GB Ram), the Corona is using 100% CPU power all the time.
When using DR, both WS, and Rendernode are using 100% CPU power. I tend to stay away from the DR bcs I like to have my WS free for work while the Node is supposed to do all the rendering alone.
Forgot to mention, I'm using the latest Corona 10 with HF1. Both machines have more than enough ram, both machines are using Win 11 (the Epyc is using Win 11 WS).
Before posting this I did search the forum for known issues of this kind and according to the forum posts, issues like this were supposed to be resolved a long time ago.
Tested the Epyc node with Cinebench, Old Corona benchmark, New Corona Benchmark, Vray Benchmark, all of them are using 100% of CPU power.
Went to the Corona System Settings (please see the image below), and everything seems to be in order.
Could anyone throw some insight?
Really appreciate all the feedback :)
Thanks,
Namik.
