when i first setup fah, i run ./fah6 -configonly
i do this to configure the client. once configured, i don't have to change any settings, i just start it and let it go. when i configure it, i tell it to not ask before fetching new units. so it will do it by itself
here is the team summary stats page. you can find yourself from there. then you can track your stats.
to manage how many cores it uses - again, this depends on how you are using the client. if you are starting it from the terminal manually, then this is easy.
example of what i do:
./fah6 -smp 7 -bigadv -verbosity 9 -local
here when i put -smp 7, i'm telling it to run 7 instances of folding.exe, and that will use 7 cores for me. on some systems i run -smp 8, but it just depends on the system. if i had a mac pro, i'd use either -smp 15 or -smp 16.
but you could use -smp 4, or -smp 3 if you wanted. since you aren't using -bigadv units, you would use -advmethods instead.
i hope this helps. let me know if you have any other questions
