Re: Guide for installing FAH v7.6.21 on Ubuntu 20.04.2 LTS

A little (non-critical) history: FAHCore priority was introduced specifically for people who try to run both BOINC and FAH. CPUs need tasks that use 100% of the resources need to be at a low priority because they tend to lock out other tasks except those with a higher priority. Running both BOINC and FAH causes the task scheduler to face a dilemma of which one to dominate the other. FAH was originally designed to run at the lowest possible priority and BOINC was originally designed to run at "slightly higher" so allowing you to bring FAH up to match BOINC was only fair. Otherwise, there's rarely anything heavy running below either of them.

And if this is a dedicated machine, set the Folding Power to Full in FAHControl.
Full power is recommended EXCEPT if your GPU is so weak that screen-lag becomes a problem for you. The OS's task scheduler does a good job of managing CPU priority but GPUs are still scheduled as FIFO without any concept of priority. That's gradually changing but the CPU task scheduler has many more years of development to rely on.
