SkyPat: C++ Performance Analysis and Testing Framework
We introduces SkyPat, a C++ performance analysis toolkit on Linux. SkyPat combines unit tests and perf_event to give programmers the power of accomplishing reliability and performance test simultaneously.
Unlike traditional tools that manipulate entire program as a black-box, SkyPat works on a region of code like a white-box. It is used as a normal unit test library. It provides macros and assertions, into which perf_events are embedded, to ensure correctness and to evaluate performance of a region of code. With perf_events, SkyPat can evaluate running time precisely without interference to scheduler. Moreover, perf_event also gives SkyPat accurate cycle counts that are useful for tools that are sensitive to variance of timing, such as compilers.
We develop SkyPat under the new BSD license, and it is also the unit-test library of the “bold” project
