Processor-Specific Thresholds

The processor-specific thresholds can be modified by using threshold scaling factors indicated in the following table:

Threshold Name	Affected Data Cell Name
TD_SINGLE_CPU_VUP_n	CPU_VUP_RATING
TD_SOFT_FAULT_SCALING_n	SOFT_FAULT_SCALING
TD_HARD_FAULT_SCALING_n	HARD_FAULT_SCALING
TD_IMGACT_SCALING_n	IMGACT_SCALING
TD_COM_SCALING_n	COM_SCALING

The n is an integer that specifies an individual processor and must be replaced by a model number. All Integrity servers use 4096 for a model number. For Alpha systems, you can get the model number of a specific processor by using the $GETSYI system service using the item code SYI$HWMODEL. An entry of zero is used for an unknown model.

A scale factor of 1.0 is used as a basis for the rules when applied to a VAX-11/780 system.

For example, the threshold construct TD_SOFT_FAULT_SCALING_40 = 0.4 places the value 0.4 in the data cell SOFT_FAULT_SCALING when a VAX model 40 is being analyzed. A VAX model 40 is a MicroVAX 2000.
