When WU's are produced from the tapes, are they a specific gender, ie CPU or GPU, or does it depend on what is being requested? I ask because at the moment, my PC is AP only (don't ask) and for the life of me |I can't get any cpu tasks, only GPU ones, despite the Event log showing boinc as requesting both cpu & gpu units.
Currently I have no cpu tasks. odd.

With one exception, workunits are 'gender neutral': most tasks are capable of being assigned to either a CPU or a GPU. They take on the specific role only on being assigned to a volunteer's computer.

When a workunit is created, two identical tasks are created to process it. The tasks are not 'entangled' - either or both can be assigned to CPU or GPU, irrespective of who decides to adopt its sibling.

The exception is for the MB tasks designated 'VLAR' (Very Low Angle Range). These are sent only to CPUs, because they can process inefficiently on NVidia GPUs, and even cause screen stuttering which interferes with the normal use of the computer.

I can't get any cpu tasks, only GPU ones, despite the Event log showing boinc as requesting both cpu & gpu units.

Your BOINC client is trying to fill Your cache to max, and it's filling faster device first (GPU). When (if) GPU cache has filled, You will receive CPU tasks.

What are Your "Store at least" and" Store up to an additional" -settings in Computing Preferences?

currently 10 & 4. I-ve set the gpu to do AP only now, and the cput to do either MB or AP, and now the cpu is munching MB, gpu is struggling to get ap's though, but as there isn't many being split, it's pot luck if I get any anyway ;-)

I have asked this question before and still don't have an answer.

My computers gets GPU tasks until cache (days) are full, then get CPU tasks.

I believe it was Mark that said his computers are opposite, CPU first, then GPU.

The only thing I can think of to case this is the order in which apps are listed in one of the config files.

As I understand it Boinc is supposed to fill the most capable processor (the GPU) first before it fills the others. What you are describing is normal.

OK, I found my original question
http://setiathome.berkeley.edu/forum_thread.php?id=77586&postid=1711430

It was Zalster (not Mark) that said

I see the opposite, CPU has to be full first before GPU gets any work

I can't explain why 2 users see different results.

I also see when filling up on MB tasks (say 30 each CPU/GPU) the downloads always come in GPU first, then CPU.

That was then, this is now, three months has passed, it has changed.

currently 10 & 4.

The larger the cache settings, the bigger the struggle to meet them.

With 8 (or even 10) & 0.05 you'll find both GPU & CPU caches will tend to fill sooner.
