nstrsched
NSTRSCHED(5) File Formats Manual NSTRSCHED(5)
NAME
NSTRSCHED - number of STREAMS scheduler daemons to run
VALUES
Failsafe
Default
Allowed values
Recommended values
DESCRIPTION
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
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
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 tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
