Performance analysis with Caliper instrumentation

Caliper is a program instrumentation and performance measurement framework. It is a performance analysis toolbox in a library, that enables you to insert performance analysis capabilities directly into programs, and activate them at runtime.

Caliper is intended for use with HPC programs, but works for any C/C++/Fortran program on Unix/Linux.

When Linaro MAP profiles a program instrumented with Caliper source code annotations, the stack of Caliper attributes with keys of interest is taken alongside regular samples. The keys of interest use the same attribute names as the Caliper high-level API (function, loop, statement, annotation). In Linaro MAP, you can see where time was spent in any set of these key-attribute pairs.
