My SMP is only using 12-13% of my CPU

When nothing else is running, my SMP is only using 13% of the cpu tops. Is this how it's supposed to be? Should I be running 8 of these to get the maximum workload out of my computer?

I have a laptop with a Intel(R) Core(TM) i7 CPU Q 820 @ 1.73GHz with 8.00 GB ram.

Oh, and I have 4 cores and 8 threads but I don't know what that means.

Hello Num1cubfn, welcome to the forum.

You probably missed a step while following the SMP install guide, and the SMP client downloaded a regular CPU work unit. CPU work units are single threaded, hence the low CPU usage. As long as you eventually got the client configured to use the -smp switch (you should see that in the fahlog.txt file), the client should finish up that CPU work unit in a few hours to a day or so, and the next work unit will be an SMP work unit and use all of your CPU cores.

Ah, so because of the type of job that I received, it cannot use my whole processor to do the job?

In the file you mentioned, I found

"[17:54:39] Work type 78 not eligible for variable processors"

But a search turned up no results for "smp". Does that mean I have to add a tag "-smp" somewhere in setup before the next work unit? And if so, how does one do that?

Please review...

FAH Install Guide: Windows SMP client installation (v6.30)

Then you can either add that "-smp" switch in the Advanced settings section, under Additional Parameters (best solution), or you can add it to the command line of the shortcut that starts your client.

Thanks you so much for your time!

Now for the 6-8 hour wait to see if it worked! :)

Welcome Num1cubfn, I see you've found your way here OK :mrgreen: lots of good information here, and some familiar posters too :wink:
4 cores is the number of real cores you have in your laptop CPU but it also does Hyper Threading so each core has 2 threads one real one virtual, therefore 8 threads.
