The POWER2* performance monitor ("monitor") provides the
detailed hardware measurements necessary to study the
hardware/software interactions of workloads executed by the
POWER2 processor. The monitor is integrated into the processor
and is fully software accessible. Of interest is the ability of
this monitor to selectively measure specific software processes
with minimal perturbation of those processes.
