I realize that credit is per task and is shared between CPU and GPU tasks, but it seems like tasks at SETI receive about a tenth of the credits that they should. I'm using the nvidia opencl linux app (AstroPulse), but I wonder if there's a way to streamline/optimize/multiply tasks that get done to maximize credits. Does running multiple tasks on a GPU help? Is there an optimized linux app out there somewhere? 15k a day using 3 half-decent GPU's just doesn't cut it, especially since I can get roughly 400k a day on Collatz between two of them when the project is up.

My wife isn't complaining about slowdowns, so I'm thinking the GPU app isn't using enough of the GPU. Also, the office doesn't feel any warmer when these apps are crunching than when there's no GPU app going.

Any thoughts?
