I'll start by saying I know nothing of programming so simple answers would be the best.
The reason for my quest is performance based and using GPUPI specifically. GPUPI is like SuperPi but uses OpenCL and runs many parallel threads from GPU or CPU. Now the performance is very dependent on which OpenCL version the software uses. I know it'll run on 1.1,1.2 and 2.0.
What I want to know is how to "make" it use one specific version. From my experience it will use the most current version it finds on the system. The only way I have found to date to "control" the version is at OS setup and driver install. By using an older AMD display driver, i can limit the choice to only 1.1 since that's the only version installed. On many systems using 1.1 over 1.2 will give a 20% performance boost which is huge.
Any help with this would be appreciated. I'm hoping some one more clever than myself could write a small .bat that would allow me to alter the version GPUPI selects at start up.
Thanks
