Abstract

Runtime tools for MPI applications must gather information from all processes to a tool front-end for presentation. Scalability requies that tools aggregate and reduce this information so tool developers often use a Tree Based Overlay Network (TBON). TBONs aggregate multiple associated events through a hierarchical communication structure. We present a novel algorithm to execute multiple aggregations while, at the same time, preserving relevant event orders. We implement this algorithm in our tool infrastructure that provides TBON functionality as one of its services. We demonstrate that our approach provides scalability with experiments for up to 2048 tasks.
