I can not find the settings.

Post by deroty »

Hi.

I installed the folding@home client.

I can not find a way to adjust CPU power. I want to use 4-5 % of my CPU withou using GPU. I am doing the same for BOINC.

I see that I have to right click on taskbar right click to Folding@home icon but there is no settings. Instructions show that if I right click on folding@home I should see settings. No settings.

I click on web control and see no option for CPU/GPU settings and how much % of the CPU. I plan 4-5% of my CPU.

No settings in my client. Can you post a screenshot how I can do that?

Thank you!!!...

Ok. I found the setting in Web control.

But I can not adjust 5% of my cpu for research. As in the link below at minimum it shows 1/8 . How can I calculate 5% of CPU? Below picture.

You can't adjust your CPU to a percentage through the client, just to use one or more CPU threads up to the number your processor supports. You can decide to not fold on your CPU by reducing the thread setting to 0. However the GPU folding core will still use a CPU thread to send and receive data between it and the GPU

Thank you. do you advise me join to a team? Will it be more efficient for folding@home? If it is not important I will not need to join a team.

You do not need to join a team. Just make certain to get a passkey if you haven't already.

Thank you. I will do that.

As a user feedback - may be you can change the settings of CPU's with a % setting. In example I am using 5% for BOINC. There can be a setting as such instead of cores with folding@home too. We can use more better and customizable. I do not want to involve with "only when idle" setting. I want to contribute as much as I can. I have other simultaneous software too.

Anyway - I will not keep you busy. Thank you.

Implementation of a CPU percentage setting is unlikely. The CPU computations are not easily done that way as the thread count is used during the decomposition of the WU into separate slices to be processed in each thread. As it is the current minimum to get assigned most CPU projects is 3.

As for "only when idle", the CPU folding is supposed to be set to run at the lowest priority. So any interactive usage will get CPU time ahead of it. The idle setting is more useful with GPU folding where interactive use on a less powerful card may have intermittent pauses as the GPU switches from folding to doing your display.

The folding core itself supports setting CPU percent usage but the v8 client does not. I think the older v7 client still supports that. It would be simple for the v8 client to support it as well. All it would need to do is pass "-cpu <percent>" as a flag to the core e.g. "-cpu 75" for a 75% cap, but it does not currently do that. I could open a ticket on the GitHub to add support. If it's accepted, I'll write the code to support it.

In theory, it should be more efficient to reduce CPU usage by reducing CPU use percentage than by decreasing the number of folding threads, because fewer folding threads will run at a higher clock rate which might paradoxically increase heat and noise.

A 4-5% cap sounds too strict and you might not be able to complete WUs in time if it's that low. If you just want to reduce heat and noise, there are better ways to do that. The core already runs at a low priority so that it does not interfere with other running programs.

V7 did not have percentage adjustment. It only had number of threads to adjust.

I forget which client supported it then. Whatever version it was, the core still supports it when the parameter is passed to it. v8 just doesn't use it.

I guess if you make a percentage setting, it will be more customized. When I run one CPU with folding, the fan starts to work. I do not prefer that. We should be able to use % as boinc. I am using boinc in my PC and it uses 5% setting.

Move the CPU slider to half of the threads your CPU has, that will reduce the heat output of your CPU massively.
And I assure you, 5% limit on each of your cores will struggle keeping up with the deadlines. Windows has 5% of CPU usage as an idle requirement for their power plans :D you cannot expect that to be enough for high compute tasks of FAH.
Whatever you do with BOINC, does not necessarily translate to the same thing in FAH. These are wastly different apps
