Scalasca

Scalasca is a toolset that can be used to analyze the performance behavior of parallel applications and to identify opportunities for optimization. It supports an incremental performance-analysis procedure that integrates runtime summaries with in-depth studies of concurrent behavior via event tracing, adopting a strategy of successively refined measurement configurations.
