Noob GPU Question...

(moderation:
Ive been running CPU W/Us on a new rig for about a month now. The CPU is a Ryzen 7 3800x. I have it running 50% of CPUs at 100% of the time. This is my daily driver so 50% works well.
I have never run GPU W/Us and would like to set up to do both CPU and GPU (if that's feasible). My video card is a Nvidia GeForce RTX 3060. Is it just a matter of marking boxes (in E@H project tab) 'Use Nvidia GPU' and appropriate 'Applications'? Is it possible to set the GPU at 50% full time?
Now... with the CPU W/U running I tried a higher % and paused when in use. Problem is, something is causing my machine to think its in use every 5-10 minutes. If I have the screen saver going it shuts that off randomly. That's why Ive been running things full time.
Any pointers would be very much appreciated!
it's not possible (currently)

it's not possible (currently) to throttle the GPU in the same way that you throttle the CPU. it will use as much of the GPU as the science application is coded for.
if you run the Gamma Ray GPU application, you will use about 95+% of the GPU for nearly the entire run (with a few seconds of lower utilization during the FP64 portion at the very end of computation).
if you run the Gravitational Wave GPU tasks, they are more limited by the CPU since some portion of computation still takes place on CPU. GPU utilization will likely be a little lower, like 60-75%.
but you can't control or change these yourself. they will use what they need, no more, no less.
but the 3060 should provide a good boost to production, GPUs are many times faster and more power efficient that CPU crunching.

Can I run both GPU and CPU at the same time? Should I just stick with GPU W/Us?
As I said this is my daily driver and dont want to slow it down til its a pain to use...

Will Gamma Ray app run on acient GPU like GTX 560Ti?

Hi Pawg! Welcome to Einstein!
I doubt this will work because of the 1MB of GPU memory that the GTX 560Ti has. Most (all?) Einstein GPU projects need 2MB to run successfully.
Anymore questions, feel free to ask. That's what we're here for.

I think long time ago was Arecibo GPU app, I've ran it on GT440 with 1GB memory

Times have changed... definitely. Einstein has some highly complex calculations for the GPU which require a bit more memory, at least 2GB is needed.
Before, I had said that your GTX 560Ti had 1MB of memory when I meant 1GB.
Many GPU of today typically will have 3GB as a minimum, while most will have at least 4GB or 8GB. If you can afford it, you may want to upgrade to a newer GPU.
As an example, even an ASUS GeForce GTX 1050 Ti 4GB is $190 on Amazon for a new one, and approximately $100 on EBAY for a used one.
Just a thought.

The 1GB VRAM size is not the problem. The gamma-ray pulsar app can work with 1GB but requires OpenCL 1.2 or better. Does that GPU have the necessary hardware support and do you have a driver that can use it? I don't use any nvidia GPUs and have no knowledge or experience that would allow me to make a judgement.
I see you are using Windows 7. Do you have a driver that supports OpenCL? What response do you get if you attempt to request gamma-ray pulsar GPU tasks?
I did look at the last scheduler contact on the website for your computer but your host wasn't requesting GPU work (0.00 secs requested). That request was almost 2 weeks ago.
Cheers,
Gary.

OpenCL is insufficient level. Can't use it.
