I have my host configured to accept GPU work for CUDA MB and ATI OpenCL AP. Basically this works fine.

But I'm not getting GPU work for AP (only got 1 unit so far!). For AP CPU and MB GPU I'm getting lots of units.

Problem seems to be the BOINC scheduler.

Here is a piece of log with work_fetch_debug enabled.

I just don't know how to interpret this.

- What does shortfall / nidle / saturated / busy / fetchable / runnable mean?

- Why am I not getting GPU AP work?

Help! :)
