13873 (0, 1518, 43) hijacking my PC

Hi dear forum.

I am new to f@h, so please forgive me, if my question seems stupid, but I am really lost and have not found any hint elswhere in the forum related to this project.

As I am in home office right now, I figured I could run f@h as my PC is running the whole day anyway. (AMD FX4300 3.4GHz, 32 GB DDR3, GTX 960). I fold on 'medium' setting while working whth MS Office and Firefox. This wors pretty well and WU get processes in a reasonable time while I cannot feel any impact on my daily work.

BUT ...

Whenever I get WUs from project 13878 my PC literally grinds to a halt with 100% CPU load continiously and GPU load in high 60iet to 100%. Yea, that type of 'grind to a halt' where it is impossible to scroll through even the smallest spreadsheet or you can fetch a coffee before that window has opened, an actually I am typing this massage letter by letter. Painstakingly. It is absolutely impossible to do work like this at all. The WU I am talking about is set to run about 24h and cannot be downgrades to 'light'. every time I tried to reduce load like this, the WU simply pauses, and does not get worked on at all. So basicly I am stuck with not working for 3-4 days, which might get me fired in a similar timeframe, or uninstalling f@h, which would make me quite sad.

The first time I got a WU from this project, it ran into some error and canceled itself halfways, but I keep getting those WUs time and again. Like today another one. =(

I guess my PC is just not powerful enough to handle this WU, but I don't know, how to avoid such overloading jobs. Neither do I know if there is a way to reject jobs that eat up virtually all resources of my machine for hours.

Any advice is greatly appreciated, and again, sorry if this is a fairly nooby question.

Regards
Arno

Since it pauses when you go to "Light" in FAHControl, this indicates to me that it is in fact a GPU project.
I think you have no other choice than to pause this while you are working. Another option is to not use the GPU to fold, so you'd have to remove the slot through the Configure -> Slots dialogue.

If you look at the Project Summary link at the top of this page, you will find that 13878 runs on "OPENMM_22", which is a GPU project.

Your best bet is to simply right-click on the "Running" tag on that project in FAHControl, and temporarily Pause it when you have to use the computer for something else. Then restart it when you're done with the computer.

Another trick is to disable Hardware Acceleration in your browser, but that won't help in Excel...

Here are links to disable hardware acceleration... I know that you can disable hardware acceleration for Microsoft Office:
Windows: https://www.thewindowsclub.com/hardware ... -windows-7
Microsoft Office: https://www.solveyourtech.com/how-to-di ... ffice-365/
Firefox: https://support.mozilla.org/en-US/kb/ha ... inds-crash
Chrome: https://www.technize.net/google-chrome- ... eleration/
VLC: https://wiki.videolan.org/VLC_HowTo/Har ... eleration/

Alternatively, you can set the GPU Slot to fold only when idle. In Windows case, it is when the screensaver comes on. Thus, you can set a blank screensaver if you wanted: https://www.howtogeek.com/225305/how-to ... indows-10/

Thanks a lot for the really good workarounds.

I am somewhar courious, what is so different with these jobs, compared to any other GPU jobs. They run perfectly unintrusive in the background. I also wonder why a GPU job eats up all the available CPU power. That is the remaining 60%.

Regards and happy folding.

The Project 13878 has 159,142 atoms which is a decent number (medium/large) so will have more computational load. However, whenever it writes a checkpoint to the disk, the CPU will need to perform some validation/sanity checks which will use all available CPU cycles during that time period.
