MPI Implementation Profiling for Better Application Performance
CoRR(2024)
摘要
While application profiling has been a mainstay in the HPC community for
years, profiling of MPI and other communication middleware has not received the
same degree of exploration. This paper adds to the discussion of MPI profiling,
contributing two general-purpose profiling methods as well as practical
applications of these methods to an existing implementation. The ability to
detect performance defects in MPI codes using these methods increases the
potential of further research and development in communication optimization.
