N2 - Characterizing the communication behavior of large-scale applications is a difficult and costly task due to code and system complexity as well as the time to execute such codes. An alternative to run actual codes is to gather their communication traces and then replay them, which facilitates application tuning and future procurements. While past approaches lacked lossless scalable trace collection, we contribute an approach that provides near constant-size communication traces regardless of the number of nodes while preserving structural information. We introduce intra- and inter-node compression techniques of MPI events and present results of our implementation. Given this novel capability, we discuss its impact on communication tuning and beyond.
