GTX 4xx Fermi Cards & 10.6.8 - QE, OpenGL/CL & CUDA Benches

[Thireus]

Hi

To upgrade on 10.6.8 follow instructions here: viewtopic.php?f=81&t=22882

About throttling issue, the topic is here: http://forum.netkas.org/index.php/topic,979.0.html

----------------

The little explanation:

Apple and NVidia are fighting for OpenCL/CUDA.

Apple by default barely support Fermi cards. These cards are not their priority! Also they do not care about CUDA.

Nvidia wants to use the CUDA technology on the market, so NVidia provides support for CUDA/OpenGL with their BETA drivers for OS X. They do NOT want to bring OpenCL support for their card. The kexts they provide into their installer overwrite Apple kexts for NVidia cards and kill OpenCL support.

So as you can see, our game is to bring both OpenCL and CUDA support for Fermi cards under OSX.

Under 10.6.7, Apple released an update with kexts to support Fermi cards. So you can have OpenCL working with Apple kexts AND CUDA working with NVidia drivers. Thus, you have full support for OpenCL/CUDA/OpenGL/QE under 10.6.7, read more here: http://netkas.org/?p=764. Basically, what you have to do is to install NVidia drivers for CUDA/OpenGL, and then erase some specified kexts with the Apple Update.

Note: NVidia Driver Installers do not only install kexts, but also Frameworks Frameworks are the key for OpenGL/OpenCL/CUDA. Kexts only tell the kernel how to use the video card when these Frameworks are used by apps. That's the reason why you need Frameworks from NVidia (with CUDA/OpenCL/OpenGL) but kexts from Apple (because they unlock the OpenCL functionality for Fermi cards).

Under 10.6.8, Apple kexts do NOT support Fermi cards anymore , like I said, this is not their priority. So NVidia jumped into the arena and quickly provided working kexts. Actually if you want to have your Fermi card working under 10.6.8 you have to install all kexts and Frameworks provided by NVidia (into their BETA driver installers).
This time they won the game, and we do not have OpenCL working anymore. We either have to wait for Apple to release updated kexts to bring back OpenCL support, or wait for Lion.

Under 10.7, Apple did a big effort and brought OpenCL support for Fermi cards

Classic Benches UNDER 10.6.8:

QuartzExtreme SEEMS OK

OpenGL OK

3.0 will be supported for Lion

OpenCL NOT WORKING

Using Pyrit (https://code.google.com/p/pyrit/) seems to be ok

#1: 'OpenCL-Device 'GeForce GTX 480'': 25353.6 PMKs/s (RTT 2.7)
#2: 'CPU-Core (SSE2)': 1082.6 PMKs/s (RTT 3.0)

Smalllux not good

OpenCL is ok under Lion after Netkas patch hack.

CUDA OK

Using Pyrit (https://code.google.com/p/pyrit/)

#1: 'CUDA-Device #1 'GeForce GTX 480'': 29219.5 PMKs/s (RTT 2.8)
#2: 'CPU-Core (SSE2)': 1020.2 PMKs/s (RTT 3.0)

Using samples provided with CUDA SDK (http://developer.nvidia.com/cuda-downloads)

Re: GTX 480 & 10.6.8 - OpenGL/CL very slow :s

As a first step i would change that

<key>GraphicsEnabler</key>
<string>y</string>

into

<key>GraphicsEnabler</key>
   <string>Yes</string>

Booleans are saves as YES / NO in Plist-Files.

Did it, nothing new

Re: GTX 480 & 10.6.8 - OpenGL/CL very slow :s

Ok, I think I know why I'm having this issue.

This is because I'm using Chamelon RC4 \o/

Now the challenge is to find a good RC5 version xD, those I tried fail to inject anything.

Have you tried the RC5 trunk releases?

Yep, but it fails to inject --> viewtopic.php?f=3&t=23135

Re: GTX 480 & 10.6.8 - OpenGL/CL very slow :s

Oh, too bad... I want to get a GTX 480 for my build too. Could you post updates when there is some progress?

Re: GTX 480 & 10.6.8 - OpenGL/CL very slow :s

Just looked around and found an interesting thread here for you. Maybe it helps you to get the GTX 480 right.

Re: GTX 480 & 10.6.8 - OpenGL/CL very slow :s

Finally I got injection with RC5 working Now my GTX 480 is fully detected

viewtopic.php?f=3&t=23135&p=148994#p148994

But perfs are still the same

your video card is? model or link in newegg

cinebech?? works in games mac osx?

thanks
