If you add up running tasks you are 7 short of the possible 24. I think the client allocated 8 CPUs for the first "atlas" but that project app only picked up one cpu, not 8. If it has only 1 CPU (not clear from looking at mpstat) then it will take weeks to finish. In any event, there are 7 unused threads and waiting WCG tasks that are unaccountably idle.
below image is from boinctasks but the manager shows exact same thing

8C usually means 8 cores.
You have 3 more cores separately running, that's 11 cores, and 2 GPUs, that 12 or 13 cores (as the GPU tasks sometimes don't fully utilize the CPU).
Presuming this is 12 cores fully used, is your hyper threading (HT/SMT) enabled in Bios?
