[Resolved] CPU usage with GPU tasking

(moderation:
When running your opencl-ati GPU tasks, the Elapsed Time as recorded by BoincTasks is approx 01:25:45 (00:02:54) while your non-GPU tasks indicate 05:31:30 (05:19:19). This is not very productive use of a GPU.
Do you have any recommendations as to how to improve the productivity of my GPUs?
I have even set the app_config.xml file to 1.0C + 1.0ATI GPU and no joy. The tasking is still about as slow as my cat is when I call her.

The BRP tasks are designed to sometimes use several cpu cores in their crunching of a single unit. It is one of the VERY few projects actually using multiple cores to crunch a single workunit. You app_config file is limiting it to only 1 full cpu core, making the unit crunch slower. I had a quad core pc here and the pc was running 2 BRP units at the same time but NO cpu units were running AT ALL! Meaning all 4 cpu cores were being used by Einstein to assist the BRP workunits. I had a dual core pc here and it was SO SLOW that I had to move it elsewhere, the dual core just wasn't fast enough to make the BRP units finish in less than 24 hours!! I had another dual core pc here but it has 2 gpu's in it and the projected time to finish a single BRP unit was close to 48 hours, I moved it elsewhere too! It was running 2 gpu units on each gpu, but there just wasn't enough cpu horsepower to make it efficient!
