cycles Measurement Report Description
Available only on Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processor
systems.
With the cycles measurement, produced by the cycles measurement configuration file, HP Caliper
measures and reports a flat profile of the instruction pointers (IPs). This measurement uses the IP-EAR
of the dual-core Itanium 2 and Itanium 9300 quad-core processor systems.
The flat profile is produced by statistical sampling of the execution trace buffer (ETB) configured
to capture IPs of retired intructions. The cycles measurement samples the ETB at a regular interval,
for example, at every N CPU cycles. This provides a statistical identification of where CPU events
are occurring.
