NSTRSCHED

NSTRSCHED defines the maximum number of streams-scheduler daemons (smpsched) that are allowed to run at any given time on the system.

Acceptable Values:

Minimum
0
Maximum
32
Default
0

Specify integer value. For more information, see Specifying Parameter Values.

Description

This parameter defines the maximum number of multi-processor (MP) streams-scheduler daemons to run on systems containing more than one processer. Note that uni-processor (UP) systems do not use an MP scheduler daemon, but both MP and UP systems always have one UP streams scheduler (supsched).

If the parameter value is set to zero, the system determines how many daemons to run, based on the number of processors in the system. The value selected is 1 for 2-4 processors, 2 for 5-8 processors, 3 for 9-16 processors, and 4 for more than 16 processors.

If the parameter 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 that this parameter is used on HP systems only, and may be removed in future HP-UX releases.
