 DESCRIPTION    [Toc]    [Back]
      This tunable defines the number of multiprocessor (MP) STREAMS
      scheduler daemons to run on systems containing more than one
      processor.  Note that uniprocessor (UP) systems do not use an MP
      scheduler daemon, but both MP and UP systems always have one UP
      STREAMS scheduler (supsched).

      If the tunable value is set to zero, the system determines how many
      daemons to run, based on the number of processors in the system.  If
      the tunable value is set to a positive, non-zero value, that is the
      number of smpsched daemons that will be created on an MP system.

      Note: This tunable is for use by specific HP products only.  It may be
      removed in future HP-UX releases.

    Who Is Expected to Change This Tunable?
      Any customer.

    Restrictions on Changing    [Toc]    [Back]
      Changes to this tunable take effect at next reboot.

    When Should the Value of This Tunable Be Raised?
      This tunable is for use by specific HP products only.  It may be
      removed in future HP-UX releases.

    What Are the Side Effects of Raising the Value of This Tunable?
      It could change the system performance unpredictably.

    When Should the Value of This Tunable Be Lowered?
      This tunable is for use by specific HP products only.  It may be
      removed in future HP-UX releases.

    What Are the Side Effects of Lowering the Value of This Tunable?
      It could change the system performance unpredictably.

    What Other Tunable Should Be Changed at the Same Time as This One?
      None.

 WARNINGS    [Toc]    [Back]
      This tunable is for use by specific HP products only.

      All HP-UX kernel tunable parameters are release specific.  This
      parameter may be removed or have its meaning changed in future
      releases of HP-UX.

      Installation of optional kernel software, from HP or other vendors,
      may cause changes to tunable parameter values.  After installation,
      some tunable parameters may no longer be at the default or recommended
      values.  For information about the effects of installation on tunable
      values, consult the documentation for the kernel software being
      installed. For information about optional kernel software that was
      factory installed on your system, see HP-UX Release Notes at
      http://docs.hp.com.
