[Bug 223517] New: Powersave: CPU scheme "dynamic" reduces CPU speed if only nice -19 processes run
https://bugzilla.novell.com/show_bug.cgi?id=223517 Summary: Powersave: CPU scheme "dynamic" reduces CPU speed if only nice -19 processes run Product: openSUSE 10.2 Version: RC 1 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: burnus@gmx.de QAContact: qa@suse.de This is with a Factory computer (update two days ago). If I choose in kpowersave in the "Set CPU Frequency mode" dialog "dynamic", the CPU frequency is reduced if I have only nice 19 jobs running: top - 23:30:15 up 2 days, 15:07, 6 users, load average: 2.14, 2.35, 2.23 PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ P COMMAND 12366 tob 39 19 1395m 1.3g 1560 R 98 63.7 515:56.96 1 exciting.gfortr 12452 tob 39 19 1395m 1.3g 1560 R 95 63.7 512:43.03 0 exciting.gfortr Expected: If any job (independent of the nice level) needs the full CPU, grant it. Reasoning: Here, we have workstations which are also used for computations. We are required by our sys admin to run computation jobs with "nice -19" so that interactive work has a higher priority. But sometimes, the computers don't have anything to do and then throttling the frequency down makes sense -- and therefore I don't want to use the scheme "Full Power", but would like to use "dynamic". -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

I don't think kpowersave is doing this currently. In the meanwhile, you can set this with the following command line, but have in mind that this setting does not persist over reboots: dbus-send --system --print-reply --dest=org.freedesktop.Hal /org/freedesktop/Hal/devices/computer org.freedesktop.Hal.Device.CPUFreq.SetCPUFreqConsiderNice boolean:true Call you call this and try again? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
