    I'm using Ubuntu 8.04 (Linux 2.6.24). The default frequency governor setting is ondemand. The governor does not consider niced processes as demand. As the Einstein applications are and should be niced, the processors usually run at a low frequencies. Is there a way to change this so that niced processes are demand? Can it be done from the BOINC Manager?

      Maybe the fix in this arcticle helps.

        That's just what I was looking for. Thanks!

          That's a nice work-around for Ubuntu and other Gnome desktop systems.

          A better (and more flexible) fix is to have the Boinc process priority settable as a parameter as is already done for such as resource share and network bandwidth and so on. Complaints about "too complicated" can be avoided by including a limited selection of (for Linux) just (nice) 19, 18, 9, 4, 0 with suitable descriptions. Eg:

          • * "nice 19 - background priority, power saving"
            * "nice 18 - background priority, no power saving"
            * "nice 9 - low priority"
            * "nice 4 - medium priority"
            * "nice 0 - foreground priority".

          That will then give an immediately visual fix for those who wish to override the power saving features and also give the number-crunching fanatics the option of sacrificing performance for non-boinc software.

          The same can be done for Macs, similar can be done for Windows (different "numbers").

          Yes?

            I like it and I think it should be critiqued and possibly refined and then written up as a Feature Request in Trac to get it in front of the devs' eyes ASAP.

            edit added for Fedora users in the meanwhile:

            Frequency scaling in Fedora 5 appears to be configured in /etc/cpuspeed.conf. In Fedora 9 it appears to be configured in /etc/sysconfig/cpuspeed.

              I also like it, and would support the enhancement.

              However, I can anticipate that the BOINC devs will consider it to be too 'geeky' and hence too threatening to include in a public release. (It's all right, we can talk freely here - no BOINC developer will ever deign to read a mere project message board).

              Would it be an easier push to suggest it's inclusion as a cc_config.xml option?
