# Test Preferences – CPU

(Applicable to BurnInTest Pro version only. Multi-CPU systems only)

CPU affinity

Normal task scheduling or CPU targeted testing can be selected here. Normal task scheduling will result in threads being dynamically scheduled on the CPU with the least load. In this way the load is spread between all available CPU’s. CPU targeted testing schedules all the threads onto a particular CPU.

Note that CPU selection is only possible if more than one CPU is installed and the user has administrator access rights.

Even if CPU targeted testing is used some load can “spill” onto other CPU’s. This is because system processes will still be allocated to other CPU’s.
