OpenCL-z Khronos ICD compatible version

See for more info: http://oscarbg.blogspot.com/2009/11/ope ... -here.html

Builtin OCL wrapper and autodetects AMD and Nvidia implementations (195.39)..
Detecting up to 4 devices in my in Windows 7 and Linux (AMD 5850,Nvidia GTX 275,Intel CPU, AMD 4850)

Notes
=====

Works with Nvidia 195.39 OpenCL ICD or higher
Works with CPUs and AMDs GPUs with AMD Stream 2.0beta4 and Catalyst 9.11 or higher
Autodetects in displays info of AMD and Nvidia OpenCL drivers in a single launch in current form..
For detecting AMD drivers you need to define the enviroment variable ATISTREAMSDKROOT where the SDK is ..
I think in Windows this is done in the installer in Linux use something as
export ATISTREAMSDKROOT..


This build is hopeful futureproof searching OpenCL ICD and also AMD while it's not ICD..

Good work, oscarbarenys1 ! It seems to me that ATI/AMD should thank you for your utility.

Great,

I am Dynamic loading the openCL.DLL, Java, so I do not understand that ATISTREAMSDKROOT part.  I do not think it applies to me.  But it is great being able to test both vendors right in the exact same run!  Crawling on the ground is not all thats it's cracked up to be.

I am already running 195.39.  I have a spare PCI & a well ventilated case.  My power supply may not be up to the job of running my 8800GTX & 4890 at the same time, but that is less $150 to fix. I will order a new power supply.

Do you have any advice for which card to use as the display, or other installation advice.  Is Windows 7 manditory, or will 6 do?

Thanks,

 

Jeff

Oscar,

I did some more checking to remember why I did not try putting gpu's from different vendors in the same machine.  I had seen posts like this one, where the unified driver architecture of Vista prohibits this.  Was this reversed back in Windows 7?

Next I thought the NVidia product you mentioned was really an acellerator, without an actual display that could be hooked on, but that is the Tesla C1060.  The GTX 275 can actually drive a display.  What am I missing?

Thanks,

Jeff

Found my answer. See #3.  Throw Vista into the garbage.
