MAQAO (Modular Assembly Quality Analyzer and Optimizer) is a performance analysis and optimization framework operating at binary level with a focus on core performance. Its main goal of is to guide application developpers along the optimization process through synthetic reports and hints.
MAQAO mixes both dynamic and static analyses based on its ability to reconstruct high level structures such as functions and loops from an application binary.
Since MAQAO operates at binary level, it is agnostic with regard to the language used in the source code and does not require recompiling the application to perform analyses. MAQAO has also been designed to concurrently support multiple architectures. Currently the Intel64 and Xeon Phi architectures are implemented.
The main modules of MAQAO are LProf, a sampling-based lightweight profiler offering results at both function and loop levels, CQA, a static analyser assessing the quality of the code generated by the compiler, and ONE View, a supervising module responsible for invoking the others and aggregating their results.
Other modules, currently in beta version, allow performing value profiling (VProf) and decremental analysis (DECAN).
