% CPU Time per daytime

Hello

Is there any way to config the client that, for example, during daytime 9:00-17:00 it uses 40% cpu, and during the night 100%.

Re: % CPU Time per daytime

If you see it, I would too. No. You can maybe script it and set an OS scheduler/cron job to process various global_prefs_override.xml files with boinccmd. you'll have to develop that yourself.

Re: % CPU Time per daytime

Thats a good idea, thank you.

If i set a cronjob to copy over a global_prefs_override.xml in the morning and another with higher cpu use in the evening, how would i tell boinc to reread config file and obey to new config?

Re: % CPU Time per daytime

If you have BOINC set to keep tasks in memory, would a cron-job to force a client restart force it to re-read the newly-changed config-file and put into effect the changes made, without losing any WU-progress?

Not something I've tested myself, I'm afraid...

[EDIT]: it seems SekeRob beat me to answering, and with a more useful answer! smile

Re: % CPU Time per daytime

Tit for tat, do not hesitate to post your script, steps and cron lines. The next who wants this will benefit. If it looks slick, I'll even create an FAQ entry with link to your contribution.

Good Luck.

Re: % CPU Time per daytime

Ok nothing slick, but does the job (i hope)

I made 2 files boinc50.sh and boinc95.sh

boinc50.sh:
#!/bin/sh

cp /etc/boinc-client/global_prefs_override50.xml /etc/boinc-client/global_prefs_override.xml
/usr/bin/boinccmd --read_global_prefs_override

boinc95.sh:
#!/bin/sh

cp /etc/boinc-client/global_prefs_override95.xml /etc/boinc-client/global_prefs_override.xml
/usr/bin/boinccmd --read_global_prefs_override

global_prefs_override[50,95].xml contain the desired cpu settings, no time settings

Then i added 3 cron lines:

0 8 * * 1,2,3,4,5 /etc/boinc-client/boinc50.sh
0 18 * * 1,2,3,4 /etc/boinc-client/boinc95.sh
0 14 * * 5 /etc/boinc-client/boinc95.sh

those should set boinc to use only 50% cpu between 08:00 and 18:00 through monday and thursday and between 08:00 and 14:00 on fridays and 95% for the rest (night, weekend, friday afternoon) so your work pc wont bother you with loud fan noises but still uses its full power when you are at home.

Re: % CPU Time per daytime

Reads like mighty fine. The various override files generated with ease through the BM interface and a little copy/renaming to make the .50 .95 versions,

Notably, 95% will effectively run as 90%, rounded to whole seconds [and as of 7.2.29 rounded to the nearest 1/10th of a second]. Practically, 95% means running 9 seconds, pause 1 second or in the new, run 0.9 seconds, pause 0.1. Why you want to 'reserve' 5% when away, I do not know. BOINC is designed to yield the floor when any higher priority process wants attention [almost anything]. Could as well run Max when the fans are howling.

cheers

Re: % CPU Time per daytime

Did not know that, thanks for explaining.

And for the 95%, personal superstition ;)
