[Max] I need help! / Re: Epyc Rome poor corona results

Hi, we wanted to assembly same PC and really interested if You can get it work normaly? What results in Corona Benchmark You have? (I see poor result 43+ sec by You and great result 12+ sec from the same PC)

Resizing helps, but this is no funny at all.

It's impossible to work today. Is this a joke?

DR caused this error at beginning of render:

An internal error occured: wxWidgets Assertion failure. Please report this problem to us.
File: ..\..\src\msw\sockmsw.cpp(208)
Function: wxSocket_Internal_WinProc
Condition: socket->m_fd == (SOCKET)wParam
Message: mismatch between message and socket?

No nodes are able to render with DR.

Hi, Ondra.

Why you're comparing picture times from absolutely different Pcs (8-thread server with 48-thread workstation) in the latest build,15845.msg106441.html#msg106441?

I've found a strange behavior of CoronaLights sampling algorithm. Look at this piture and scene attached. There are areas with good and bad sampling mixed. Is it a bug or may be I'm doing somthin wrong?

It seems that bloom and glare effects are not being saved with network rendering. I can't get it saved with backburner job on nodes.

Update: Looks like this node having trouble with saving image with effects. Investigating it.

Update 2: Looks like it is not saved at all. If I render sequence there are no effects saved in file. 3ds max 2014

So I wonder how much faster it would be otherwise... (maybe not at all, maybe the AVX does speed-up something, although all my friends working with it assured me it's minimal )

May be. But I would like to seу maximum clock speed as it can be without AVX.

Yea. But it's still quite fast. Let's hope that we'll see AVX gone or will be used to increase speed instead of decreasing it.

We've bought 20 Cores XEONs - all cores areused in rendering. It's good.
AVX is in use and lowering cores speed - it's bad.

Regarding AVX, this isn't Haswell-E/Broadwell-E  "issue", but Haswell-E/Broadwell-E Xeon E5 v3/v4 thing, apparently because of their tighter thermal design (see the picture I attached from Intel presentation). It's about 300Mhz difference in turbo-bin depending on individual chip, I couldn't find where Intel actually lists this info.
But it doesn't do any kind of havoc, this is just one of those 'potential' losses, these CPUS are still fast as f*** :- ). Like....really nice.

You mean that Turbo Boost can't boost from nominal base frequency or it will lower уму base frequency down? If I have 2699 v4 with 2.2GHz (2.8 all cores with TurboBoost) I will end up with 1.9GHz lowered CPU in Corona? Or it will boost it to 2.5 only (2.8GHz -300MHz)?

I wrote that Corona (and also Vray from 3.3 service pack) works 100perc. with processor groups :- ).
I also wrote it many times, maru did, ryuu did, yet people still have doubts ;)

Sorry... I got it now. Great, but not for AVX.

6900k has only 16 threads so it will be impossible to see more than one processor group in windows. So Turbo Boost is working as expected. My question is will Corona use more than one processor group if threads more than 64 present.

So it will not be a problem to use all 88 logical processors (in dual 22-core system) with Corona? No need to setup any sort of DR to use all threads or something else?

About AVX. Is it applicable only to Xeons v4 or every Intel CPU? I tested Corona benchmark with 2600k and 3930k and hasn't seen any sort of lowering frequency. Turbo Boost was used to rise frequency to max for all cores and I had no issues with it.
