	Is it possible to crunch for GPUGRID with only the CPU? I understand it is primarily GPU-oriented, and I'm ok with irregular tasks, but is it possible to participate with only a CPU?

	You have a couple things wrong I believe. First you are in contention with WCG as it is also requesting work. Second, you should remove the additional work request limit or set it to only 0.1 days. Then you need to bump up your primary daily work request from the 17260 seconds as the GPUGrid work request of ~35,000 seconds exceeds that. You shouldn't need that much time to finish any of the QChem tasks, but if you are also requesting Python, ATM or acemd3 tasks, then you need the additional time to finish computation on those tasks. But the 3080 laptop gpu should be able to do those in those times as long as you don't have a lot of cpu contention. That's an issue with laptops that share cpu resources with Intel igpus which your output shows as also being seen. I'd reduce your cpu contention to 50% to adequately support your Nvidia gpu. Also make sure you have done a recent cpu benchmark to profile your host and have its processing speed coincident hopefully with the task rsc_fpops_estimate values the tasks are set up with.

	Sorry for the multipost, I did not intend to post my message here , I must had multiple tabs open and mixed stuff up confused. But since the reply is here: How do I increase my primary daily work request to 35,000 seconds? How do I reduce my CPU contention to 50%?

	Sorry for the multipost, I did not intend to post my message here , I must had multiple tabs open and mixed stuff up confused. But since the reply is here: How do I increase my primary daily work request to 35,000 seconds? How do I reduce my CPU contention to 50%? You change your work request in the Computing Preferences on the website or in the Computing Preferences locally in the Boinc Manager. There are 86,400 seconds in a day. Your current preferences are set for 0.2 days. If you want 35,000 seconds of work, then set your daily request to 0.4 or 0.5 days. Same places to set your cpu usage. Instead of using 100% of your cpu cores, set to use 50% of your cpu cores. https://www.gpugrid.net/prefs.php?subset=global
