I have noticed that additionaly to the standart WUs there are some taking only half the time of normal ones. When looking at the tasks iv seen that the short ones get done considerable faster on a CPU.

when normally it is the other way arround

Why is that and isnt there a way to sent the "short" WUs only to CPUs. The GPUs seem a bit wasted on those.

I believe all the units are the same here, meaning there aren't any short or long units. Your gpu is very fast and very new, that could be alot of why it seems 'wasted here' doing the workunits. Alot of us have much older gpu's and the project needs to support us too, as we are there bread and butter. All projects deal with how to cut off old hardware, and/or make new units that better support the capabilities of the newer and much faster hardware. Projects appreciate your hardware as it just flies thru the units, whereas mine tended to be alot slower.

You missed my point. Was asking why this happens:

Yet granted full credits. If its normal, all good. Just wanted to point out that this happens. And if there is a way, it would be better to sent these types to CPU only.

I believe every workunit is EXACTLY the same, a workunit is a workunit until a pc asks for some, then depending on what it asks for the ones they get are labeled as such for security purposes. So if your cpu asks for units you get units labeled for your cpu, but the exact same unit could have been labeled for an opencl or cuda gpu instead if that request came in first.

So 'it's normal' what you are seeing.
