F@H SMP2 using only 50% CPU usage?

Mario1 · Sep 4, 2010

Could somebody tell me what did I do wrong?
When I run F@H I complete 1% in 6 min every time, CPU usage stays on 49-53% its like 10 min faster than when folding on win XP and I bet that I'll fold even faster with CPU utilized @ 100%...

You are running a classic single core work unit. Need to add the "-smp" parameter to your client.cfg or create a shortcut to start the client and add the parameter to the shortcut.

To avoid cluttering your desktop, suggest making a "folding" folder with sub-folders for each client. My CPU client files are located at c:\folding\FAH-1. My GPU clients are located at C:\folding\GPU-1, \GPU-2...

To modify the client.cfg, a shortcut to start the CPU client with the "-configonly" parameter in C:\folding\fah-1 would have target field like:
C:\folding\FAH-1\[email protected] -verbosity 9 -local -configonly

A shortcut to start the CPU client with the "-SMP" parameter in C:\folding\fah-1 would have target field like:
C:\folding\FAH-1\[email protected] -verbosity 9 -local -smp

I added -smp when configuring the client.
After (just) finishing a WU the client started downloading a new core -

and now my CPU is utilized @ 100%, thanks for helping!

EDIT: I added -smp 2, because my CPU is dual-core, is that right or I'll be fine without the "2" after -smp?

The current SMP client should default to the max cores detected. Only reason for a number value is to restrict the client to less than the max cores. My regular quad core clients do not have a number value on the -smp, but my i7 running bigadv still have smp -8 per the original bigadv instr, although the value may no longer be required.

Ok, so I might as well make it -smp only, than.
Thanks for introducing me to the mysterious world of protein folding

F@H SMP2 using only 50% CPU usage?
