Reducing 1 CPU with one GPU

My experience with the latest Intel GPU tasks is that the notional CPU/GPU job description doesn't necessarily entirely describe the way that resources will be used.

Like:  hsgamma_FGRPB1G_1.22_windows_x86_64__FGRPopencl-intel_gpu.exe

For example, many GPU jobs effectively require no real CPU input - often running at 0.4% of a core while the Intel GPU runs flat out 100%.

This means, if you are running multiple Einstein tasks or other background processes (in my case often some Folding@Home tasks) - on a 4-core Intel i5-4430 CPU with built-in GPU , if you set 2 cores for Folding@Home & 50% of CPU (ie. 2 cores) for Einstein, the resources used will be:  2 cores for Folding@Home + 1 core running a non-GPU Einstein task + the built-in GPU running an Einstein GPU task & its owning task only using ~ 0.4% of a core (0.1% of the CPU) = total ~ 75% of CPU.

Stepping Folding@Home up to 3 cores then works fine:  3 cores for Folding@Home + 1 core running a non-GPU Einstein task + the built-in GPU running an Einstein GPU task & its owning task only using ~ 0.4% of a core (0.1% of the CPU) = total ~ 100% of CPU.

The reason I say the actual usage doesn't match the task descriptions is that the Einstein GPU tasks I have received tend to say 0.5 CPU + 1 GPU or 1 CPU + 1 GPU while in practice either tends to require almost no CPU core time to run.

The only difference on an i5-4430 between 0.5 CPU + 1 GPU vs. 1 CPU + 1 GPU is that a 1 GPU task makes screen update slow & rather impractical for word-processing or spreadsheet input whereas a 0.5 GPU task seems to have enough screen-update leeway to be bearable.

LOW-POWER

On a low-power Intel processor with built-in GPU the results are rather different (eg. m3-7y30 - a 2-core, 2-hyperthread core CPU [effectively appearing like a 4-core CPU] with built-in GPU).

A 0.5 GPU task seems to run pretty well & you can run 4 other cores to use ~ 100% CPU while GPU may run ~ 25%.

Running a 1 GPU task does not seem to work at all well - total CPU usage tends to be limited down to ~50% while GPU use is ~100%.  I presume the CPU-limiting is the usual low-power Intel CPU approach of reducing the CPU processing to keep the CPU at a sensible temperature.

My conclusion is that it would be handy to be able to specify 0.5 GPU tasks are ok but 1 GPU tasks are not practical but at the moment I have both types download - ideally I only want the viable ones with 0.5 GPU.

Is it possible to specify 0.5 GPU tasks only?

Thanks
