Open CL not just an option, but a requirement?
Hello, I have successfully installed 2 Nvidia GTX 470’s in my 2010 Mac Pro so that I can easily switch between Adobe CS5.5 and Davinci without any problem. One card has 2 monitors attached for the Adobe Mercury Engine, and the other is only for CUDA use by Davinci Resolve.
However, I have taken out my ATI 5770 to make space for the GTX, which is definitely more powerful. Now I am getting the “No open CL Boards Available” messages at startup.
Does this mean that Open CL is not merely an option, but now actually a REQUIREMENT to run Resolve?
If so that would strike me as extremely limiting, and frankly pointless. Nowhere have I seen this written. Instead of providing another option it merely becomes another straightjacket if it is true.Perhaps I am misintrepeting this, and there is an error somewhere. Feedback is welcome.

No, as far as I know OpenCL isn’t required. However, might your Mac be confused when it recently had an ATI card, but now it doesn’t? Remove ATI drivers somehow?

Can you make sure there is nothing in the Preferences/Debug section?
Also, make sure you have the latest CUDA drivers installed if you are running Lion.

Hi Clayton,
Can you send your logs to davincihelp@blackmagic-design.com?
It sounds like your machine wasn’t seeing the Nvidia Cards.
I’m sure I can help you out!
thanks,

Nothing in the Preferences/Debug section. Latest drivers for CUDA installed (I am on Lion) 4.0.50.
If I put the 5770 back everything works fine, take it out and it keeps looking for OpenCL. In terms of the drivers for that card, there are none in a seperate package. ATI doesn’t offer it on their site either, which means that it is integrated into a package with Lion. When I do search for them on the computer, nothing comes up, so I can’t throw anything away.
The system sees the Nvidia cards in both slots under graphics/displays and in the PCI section. Obviously, as I see my monitors, the cards are working for the GUI off of either of them. Whether they are actually being put to work by Resolve is another story. Is there some kind of program out there to see how many cores are active on a card at any one time by the way?
So right now remains a mystery.

How did you fit two 470’s in a Macpro?

[Joseph Mastantuono] “How did you fit two 470’s in a Macpro?”
No problem, since I am not using a raid card. The four internal HD bays are enough for the time being. The top slot is for a Blackmagic card. The real issue was the power, but finally I just pulled from the unused SATA connector in the 2nd optical drive bay. Everyone was like oh no don’t do that. But I use “Hardware Monitor” to see what is happening temperature and power wise all the time, and guess what? It shows me that it pulls so little extra power that I don’t even hit half the capacity of PSU most of the time.
So here is the deal with the two GTX 470’s and the OpenCL warnings. Basically as someone suggested Resolve was not seeing the cards, so it was looking for something – anything. Hence “where is openCL?”.
However, it appears the issue is that even though Lion installs CUDA drivers automatically now, it does not install the right ones for what we need to do. Is it possible to uninstall the OSX Lion version and replace with Quadro 4000 drivers? No way. A nightmare. Believe me I tried. Until my computer froze up.Very poor internet connection where I am working currently (a basement).
Therefore not possible to reinstall Lion – no discs. What a terrible idea on Apples’s part, at least give us the choice!“What a lovely opportunity to get rid of this nightmare operating system!”, said I.
Reinstalled Snow Leopard, and then the drivers for the Quadro 4000 for Mac. Works like a charm now. End of story.

A little UPDATE**
What I discovered was that my Assimilate Scratch was not seeing the CUDA drivers. As a lark I tried installing the same OSX Lion CUDA drivers (Nvidia 4.0.50) over-top of the Quadro ones and it worked. Scratch could now see the CUDA cards and Resolve continues to be healthy.
What this tells me is that you must install the Quadro 4000 for Mac drivers FIRST (Nvidia 4.0.19) and then you can put the later version on top (Nvidia 4.0.50) if you so chose. Otherwise you cannot backtrack if you go directly from the latest version to get the earlier set. As this is rendered impossible by an OSX Lion install, I do not recommend Lion for GTX 470 users right now.

Mine runs just fine, with both apps.
But yes, I have a GT120 doing the UI.
The GTX 470 remains a great computing but a poorly supported (hence inofficial) primary card.A slice of color…
