Syntax

SequenceCallModule.CustomCPUAffinityForNewThread

Data Type

String

Purpose

A numeric expression that specifies the CPUs on which the new thread executes when the value of the SequenceCallModule.CPUAffinityForNewThreadOption property is CPUAffinityForNewThreadOption_UseCustomAffinity .

Remarks

This property evaluates to a numeric value in which each bit represents a CPU. The lowest-order bit represents the first CPU. For example, a value of 12 , which is 1100 in binary, represents CPUs 3 and 4 on a quad-core computer. A value of -1 specifies to use all CPUs available to the process.

The value this property specifies applies only if the value of the SequenceCallModule.MultithreadingAndRemoteExecOption property is SeqCallMultithread_NewThread or SeqCallMultithread_NewExecution .
