Intended Audience

This document is written for software developers who want to improve the performance

of their application programs. It assumes that you are familiar with compilers and with

performance analysis concepts. It is not necessary for you to have used a performance

analysis tool before to use HP Caliper or the HP Caliper Ktrace features. To obtain the

greatest benefit you should be familiar with HP-UX internals and have access to HP-UX

source code. However, having HP-UX source code is not a requirement to using HP

Caliper and HP Caliper Ktrace features.
