DECset - PCA (Performance and Coverage Analyzer)
The VSI Performance and Coverage Analyzer (PCA) for OpenVMS Alpha/I64 Systems helps users pinpoint execution bottlenecks in application programs. PCA can also identify which parts of an application are not executed by a given set of test data.
VSI PCA is a part of DECset.
Features
PCA collects performance and coverage information on your application and lets you analyze that information to learn about the run-time characteristics of your application, such as:
- Where your application spends the most time;
- What parts of your application are executed the most;
- What parts of your application are executed the most;
- What areas of your application are executed (or not) by tests;
- What parts of your application are compute-bound or I/O-bound;
- What the dynamic call relationships are among the routines in your application;
- Where page faults occur;
- Where your application uses system services;
- Where your application executes vector instructions.
