Need Help with app_info.xml for HYBRID ATI GPU/CPU Optimized AstroPulse_v505 5.0

Raistmer:
how many GPU do you have in that host?

Only 1 GPU. But since the Hybrid AP app uses it only every 5 minutes or so for only a few seconds I thought I could run 4 AP tasks in parallel (since I have a quad processor).

Raistmer:
Currently 2 active tasks per GPU limit is embedded into app itself. It was done as protection from BOINC sheduler (at time when app was written BOINC had no support for ATI GPU and could run too many AP instances). Also, running too many AP instances is useless (GPU memory has limited amount and hybrid AP use GPU memory well enough).
That is, you limited by 2 AP instances per GPU.
To get full GPU usage I encourage to crunch for another project (like MW) too. If you SETI-only participant then just live some time with partially used GPU (it will use less energy too btw ;) ) - new ATI AP version will have better GPU usage.

[Maybe I will do additional build w/o hardwired limitation of number of instances, will see]

Do you know roughly when this app will be available?

By the way: Big thanks for your efforts to optimize the apps!!! And for your instant replies to all my stupid questions :)

Hey, Nice work on the apps, need a little help with the app_info.

Quad Core Q9300 + 2 ATI 3870X2, running seti 100% of the time.

I want to get the most out of it, second gpu (device 1) show no spikes at all,
but boinc shows "running (0.01 CPUs + 1.00 ATI GPUs (device 0)" and
"running (0.01 CPUs + 1.00 ATI GPUs (device 1)", but both items are processing items.
