Multiprocessor Parameters
Multiprocessor parameters allow you to
 Set the threshold for load balancing across multiple processors.
 Start secondary processors automatically on startup.
 Control whether interrupt statistics are removed from memory when a
processor is taken offline or an interrupt handler is removed.
Multiprocessor parameters are described in the following table.
Table 12 Multiprocessor Parameters
Parameter Use to
System Threshold = number Adjust the load balancing threshold for multiprocessor servers.
This number controls the main value used in calculating thread
shedding for load balancing across multiple processors. The
optimum value has been preset by Novell.
Supported values: 0 to 102400
Default: 1536
Important: The default value is the optimum value. We
recommend that you retain it. If after careful consideration you
decide to change the setting, experiment only in a nonproduction
environment.
You can set this parameter in the STARTUP.NCF file.
Auto Start Processors = value Start secondary processors on startup.
Supported values: ON, OFF
Default: ON
ON = Secondary processors are automatically started when the
Platform Support Module (PSM) is loaded.
OFF = Secondary processors are not automatically loaded on
bootup. When this is the case, the command START
PROCESSORS must be used at the console prompt to activate
secondary processors.
This parameter is preferably set in the STARTUP.NCF file.
