Logicalization of communication traces from parallel execution
Abstract
Communication traces are integral to performance modeling and analysis of parallel programs. However, execution on a large number of nodes results in a large trace volume that is cumbersome and expensive to analyze. This paper presents an automatic framework to convert all process traces corresponding to the parallel execution of an SPMD MPI program into a single logical trace. First, the application communication matrix is generated from …
