CPU usage low?

[Deleted member 12106]

One of the boxes I have folding doesn't have the typical 100% cpu usage. Could someone offer up some advice? I did restart the client.

You need to add the -smp 8 flag.

Mapping NT from 1 to 1

It looks like fah is only using 1 thread. Your system has 8 threads, so you should see "Mapping NT from 8 to 8".

Try added "-smp 8" to the command line when launching fah. This should force the use of 8 threads.

My $5 is on this

Neat. I must have missed that in the how-to.

I went back and looked on my shortcut, the others I put the -smp flag but not that machine, this one I did not. Also reconfig'd another box today and have 8 cores dedicated to F@H.

How can I schedule the cores? For example, I have one box that I cannot give 100% usage to. I can give 50% of it to F@H daily, and 80% off hours/weekends.

I think you pull the NEW work units for 16-core.

Might want to check with tear, grandpa_01, untitledone....

I had thought this would be if I did -bigadv? I am thinking I would leave it on normal WU, or is this not what I would want to do?

From what I read in this thread: http://hardforum.com/showthread.php?t=1671553, folding normal SMP would yield higher point atm than bigadv.

This is not true. bigadv has had no changes. -bigbeta has a new BETA work unit with wonky points. I'm sure this will be addressed in the future. If you are running -bigadv, you will not see the beta unit.

I would just stick with 50% all the time. Some WUs do not like a change in thread count mid-calculation.

+1 - make it simple on yourself.

Either that or use 7 threads, that will leave one open for you all the time, then you can use an affinity ap to lock fah to 1-7 leaving 0 open for your use. We used to do this back when GPU and SMP rigs ran hand in hand.
