Deadline Scheduling Proposed For the Linux Kernel

Posted by timothy on from the work-expands-to-fill-the-available-time-slices dept.

c1oud writes "At the last Real-Time Linux Workshop, held in September in Dresden, there was a lot of discussion about the possibility of enhancing real-time capabilities of Linux by adding a new scheduling class to the Linux kernel. According to most kernel developers, this new scheduling class should be based on the Earliest Deadline First (EDF) real-time algorithm. The first draft of the scheduling class was called 'SCHED_EDF,' and it was proposed and discussed on the Linux Kernel Mailing List (LKML) just before the workshop. Recently, a second version of the scheduling class (called 'SCHED_DEADLINE,' to meet the request of some kernel developers) was proposed. Moreover, the code has been moved to a public git repository on Gitorius. The implementation is part of a FP7 European project called ACTORS, and financially supported by the European commission. More details are available."

      I didn't get the first post because pulseaudio crashed my system, and my wifi wouldn't connect.
      Then I had to finish my windows 7 torrent, install it, and now I can post.

      Linux isn't ready for the first post.

      Linux isn't ready for the first post.

      But Windows is ready for the last post.

      It isn't PA that's crashing your system. It's the drivers, and PA just exposes defects that were already in the drivers.

      IMHO, Windows is ready for the whipping post.

      Thanks PulseAudio, for exposing those damn drivers. I really hate it when audioservers simply work and just hide defects like this.

      And I suppose that PulseAudio is just exposing flaws in Linux, right? Lame.

      I really like the design of his website. Even IE renders it correctly... That's what I call a clean design, UI experts and gnome devs take note!!

    Somewhere there's a 57 year old grad student waiting for his job to finish running.

    And then the server shut down.

    Ouch.
