Sorry, a bit off topic, but have you tested hybrid rendering on a Ryzen system through distributed rendering? My Ryzen will render hybrid locally, but not over DR. I posted a new topic about this, just wondering if you could tell me that it has been tested to work.

Yes, it should work fine.
You have to enable the C++/CPU device on the DR machine though. You can do this with the "Select devices for V-Ray GPU rendering" tool that comes with the V-Ray installation (https://drive.google.com/file/d/0B5q...w?usp=drivesdk) - https://drive.google.com/file/d/0B5q...w?usp=drivesdk, or by manually setting environment var VRAY_OPENCL_PLATFORMS_x64=c++/cpu;nvidia on the remote machine.

Best,
Blago.

Or should I say epYc. Get it?

Nope, please explain for us slow ones

Hi,

I'm about to get 4 new machines, and want to know for 100%, from Chaosgroup, that having a mixed render farm is no problem!! I know it used to be a long time ago, but I cant spend 1000's and get different renders!!

These 1950x chips are beasts, and such good value.

Thanks,
Mark

Yes, I did do that. Same procedure I used to get my i7 machine to work. That's why I can't think of anything else it might be. And I can get it to use the cpu locally, just not over DR.

For me personally it has been fine adding a Ryzen chip to the otherwise Intel farm. I was getting a few dark buckets on very random occurrences, but it turned out that I just needed to install the latest service pack for Max. I'm thinking it could have been a color correction setting or something like that. But defintely not AMD/Intel related. I love the performance of the 1700 so much I already have the 1950x on pre-order. The 1700 even at 3.75ghz is still more than 2x faster than my 6-core i7's and 3.3x faster than my old 2600k. I'm going to make Threadripper my new primary workstation. Can't wait.

It should work fine. Can you send the V-Ray log from the DR machine?

These are releasing in a few days right?

Can't wait to see the benchmarks!

cpu power is cpu power man. Its not they are using another type of architecture and translation for it to work. The main thing you should be concerned about is how to best optimize your farm depending on how you render so that fast machines aren't held up by the weakest link (depending on how and what you render). But thats where queueing and balancing software comes in (if your doing alot of production).

That might be true, but unless my memory is failing me, a while back there was an issue with a mixed render farm, and as I'm about to sink north of 15k into machines, I just want to be sure, and get Chaos to confirm before pulling the trigger!

I guess you should ask AMD about that ...

Hi Blago,

Not likely to get a response from AMD about a specific software on their hardware, I had hoped you would have tested on your Threadripper machine to see if anything differed? Are you out of NDA yet?

[delineator]

Embargo is still on. I mean, its not like you can actually buy it now, but I just really do not understand what your asking and why. I have a ryzen and it renders vray on my farm. There are also threads testing embree on ryzen (it works) . Are you asking if the architecture on threadripper is different than ryzen? Or if the extensions/instruction set will preclude it from running vray? I mean, doesn't x86 = x86? Imagine if this carried onto other programs, engineers would have to make sure they are all running the same computer so that rounding discrepancies don't exist. Accountants would be in a world of trouble. Its just very hard to imagine.

Any link to the mixed farm issue? Literally have never heard of that and am very skeptical.

[savage309]

It is not the embargo that is the problem. So far we have tested many Ryzen CPUs - they worked fine and performed as expected. Threadripper benchmark with V-Ray Bench was showed during the AMD SIGGRAPH keynote by AMD.
To say that we guarantee that they will render exactly like the Intel CPUs however is unlikely to happen - there is no way for us to be able to test enough scenes and compare them. Also, this will never depend only on us (if at all) ...

Best,
Blago.

Epyc (code named "Naples") is the name of the highest tier of AMD processors which have up to 32 cores/64 threads per CPU. The 32 core chip is available for "only" $2000 for the single socket variant. They have a version that also works in dual socket mode and starts at $3200 per CPU.

I've ordered a 1950x Thread ripper and mobo. I'm retiring my other boxes and consolidating down to just the one. It will have 64gb ram too as sometimes I find 32 not quiet as much as I could use

Got some serious water cooling for it too so I can have it run at 4ghz
