  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

New Mac Pro

Hilarious that one can fix AMD OpenCL issues by installing nVidia drivers.

Actually it's not hilarious. Resolve requires you to install CUDA, whether you have an nVidia GPU or not. And you need to keep CUDA up to date so it can interface properly. Maybe they will fix this with Resolve 11?

Isaac, you are not smoking crack and keeping CUDA up to date may also play a role with Adobe CC as well. Premiere does like to see CUDA installed, or seems that it did in the past. I never investigated a link there, but for Resolve there definitely is a connection. Has to do with how they've implemented their GPU acceleration engine and it seems OpenCL rides along with Cuda as a fall-back or secondary measure.
 
If others run the cuda update and that makes the crashes go away we may have confirmed a solution. I'll go take the rest of the day off and give myself a raise.

I find it hilarious.

I didn't know that about it requiring CUDA to use OpenCL on AMD hardware. Amazing that one is forced to install drivers for hardware they do not have in order to use software that they do. I mean, how are we supposed to escape the crushing oppression of CUDA if we have to continue installing it in order to make OpenCL work?
 
I suspect Davinci just implemented base Open CL into their player that translates over to the Native Cuda in the player. As far as I have seen Adobe doesn't require Cuda installed and the Open CL is full implementation. Remember like Open GL and DirectX, Open CL is a standardized programming model. If OSX places the Open CL library files into common component directories then any software/driver install that updates those common library directories will update it for any application and driver that references them. Windows has similar though many video driver components in the install are not installed into shared common library directories.

If we look at how GPU acceleration in Resolve has come about it makes sense in some ways. They have been using CUDA for some time and OpenCL support is very recent. Of course, none of the CUDA operations are available on non nVidia hardware, but the software probably needs CUDA there for interaction with their GPU communication layer or at least for the CUDA portion to stand up every now and then and say "hey, I'm not the droid you're looking for… move along."

It's not an issue of making OpenCL work. It's an issue of making a specific application work because it's still developed around a CUDA-dependent code base.


Anyway, not saying this is the solution. It's not, as I was still seeing flakiness, just not as bad as some others are reporting. I did roll back to the last 10.9.3 beta seed as it's much, much better. A very curious situation for sure. As indicated in posts above, Apple did something funny here and released an update that spent ZERO time as a beta seed. Normally they circulate the final seed for a week or two before releasing it. This build is an entirely new build with new changes, and bugs, that were not present in the final beta seed released under a different build number only a week prior.

Jeff are you able to export out of Adobe Premiere or Media Encoder with GPU acceleration on after that Cuda update?

I asked Kevin in the Creative Cow Forums if Adobe's Open CL references the Cuda Player at all since there is a thread active there with regards to this issue. Adobe may be doing that as well though I never thought they would implement that way. That creates way to many variables causing issues down the road where 1 GPU acceleration version updates and the other 1 doesn't. Then references break and the translation breaks down. This would be a nightmare long term and not good for Open CL users both performance and stability.

I'm able to now do exports out of Media Encoder with the update. Media encoder offers a quick test, as before the CUDA update just setting it to OpenCL and hitting start would hardlock my system. Now it's okay. I've yet to try Premiere. But so far all systems seem okay.
 
Update: Premiere can finally do exports without major video garbage. But OpenCL playback WITHIN the app is still buggy. So I'd say this is 2 steps forward, 1 step back. So apple or WHOMEVER needs to fix this still.
 
I just plugged in my 4k sony to the Mac Pro today (i have had the 4k sony for a few months), and it worked right out of that batt. Must have been some difference or something since i was having problems on that display a few weeks ago(couldn't get it to 4k from the mac). Anyway, its nice to see the 4k integration is getting real easy.

Apple's Developer Conference is now only 2 weeks away, and it'll be interesting to see if they have anything to say about 4K. 4K monitors are still a missing piece of their current hardware line.
 
I have / still have Major render problems with Adobe Premiere CC on 10.9.2 with the new Mac Pro. (I render with software mode everything is fine.) So looks like it always been there in some way...
the problem ALWAYS occurs when I have multiple layers stacked.
Not at the office right now, but have to check if CUDA is installed. (hope that makes a difference then)
 
I can encode from AME/ Premiere. It's still glitchy and has issues. No more issues for me under 10.9.3 than I've had under 10.9.2 or 10.9.1. Adobe CC is just buggy on the nMP until Adobe releases their big update that is promised to not only fix these issues on the nMP specifically, but to also bring us better Dragon support, R3D GPU support, etc..

Can't test it without CUDA at this point and never really did. CUDA is always there and updated because Resolve and a few other oddball CG tools need it for compatibility purposes. So I keep it up to date, even though it serves no logical purpose on the system other than to facilitate legacy software implementations that haven't transitioned to a neutral GPU base.
 
Anyone know where you can get the best deal on memory upgrade? Checked Crucial but their prices seem to have gone up substantially in the last two weeks.Never ordered from them before so was wondering do their prices fluctuate from time to time.Also any difference in RAM quality?

Thanks.
 
macsales.com is usually pretty decent prices/quality
 
OWC (macsales) is great. And Crucial is fine too...

While memory prices are often volatile, prices have been holding steady so far this year and have actually slowly moved downward. A 64GB kit is $50~$75 cheaper now than when the nMP was first shipped. So I'm not sure how this plays into your availability in Ireland, but here in the USA, I haven't seen anything more than the recent downward trend. Crucial is currently cheaper than OWC -- $755.96 for a 64GB kit vs. $799.95 from OWC. Crucial kits can often be found a bit cheaper through independent sellers. There are also compatible modules from Samsung. Apple is using RAM from Hynix. You don't have to buy modules that are specifically labeled as for the new Mac Pro, you just need modules with the proper specs -- they're standard hardware with nothing special added.
 
Thanks for the reply and info Jeff.
So I ordered the machine yesterday-6 Core/256GB PCIe/D700's... and now looking to start the RAM upgrade.
I would have maxed it out with 64GB but reading some of your other posts Jeff I was wondering if this is in fact the best option.You mentioned something about a 3x rule?
Does the amount of cores you have depend on how you much RAM you should configure you're system with?
Also what is the difference between Registered and Unbuffered RAM?-is there any difference performance wise and what would be the best for the system I ordered as there is a €50 difference in the 2 on Crucials European Store.
As I said I just assumed the more RAM the better but to be honest I'm new to setting up a pro workstation so just want to make sure I'm configuring it the best way with the budget I have.


Here is the best options I can find price wise at the moment(again even though they are both Crucial brands,Im not sure if they are the same?)

(cheaper for me to buy on .com site as opposed to .co.uk)

Any help appreciated....thanks guys.

I'm just away to order up RAM for our 6 core nMP which is due to arrive this week and I'm wondering the same. Does look like you can only get Registered RAM in 16GB modules though.

I'm looking at Crucial and they are still considerably cheaper than Apple.

On the storage front I'm still trying to decide between a Pegasus2 and the Areca 8050T2 - I know this has been discussed previously, but how is everyone getting on with these units? The Pegasus does not use enterprise drives but I'm not sure if this is truly a deal breaker. The Pegasus2 also comes ready to roll as opposed to having to build and set up the Areca unit...support is also very important and when things go bad, I'm wondering if Promise will offer better help than Areca?

Best wishes

Scott
