Hi all,

I'm trying to find a way to allow my CPU to process WU's all the time, but only allow GPU's to process at a set time.

We have cheaper electricity at night so I'd like to take advantage of this.

I've tried altering settings in both the BOINC Manager GPU and the cc_config.xml files but have only succeeded in stopping and starting all processing at set times. I am unable to differentiate between GPU and CPU.

Any suggestions would be most welcome!

Thanks

EDIT: I should add that I'm running 64 bit linux (Ubuntu) with x2 AMD 5870's (not SLI) and an AMD 1055T CPU.

Use BoincCmd and set up a schedule to Start and Stop GPU usage:

http://boinc.berkeley.edu/wiki/Boinccmd_tool

--set_run_mode {always | auto | never} [ duration ]
Set run mode.
## always: do CPU work always
## auto: do work only when allowed by preferences
## never: don't do work

If duration is zero or absent, this mode is permanent. Otherwise, after 'duration' seconds elapse, revert to last permanent mode.

--set_gpu_mode {always | auto | never} [ duration ]
Set GPU mode. Like set_run_mode but applies to GPU computation

Hi Claggy, thanks for the response.

Are you suggesting that I use the boinccmd tool within a shell script to specify a sleep period? I.e. tell it to sleep for x seconds during the day via a cron job?

Or is there a way to specify a start and end time of each mode {always|auto|never}?

Sorry for my lack of understanding
