Scalasca

Scalasca is an open-source toolset that can be used to analyze the performance behavior of parallel applications and to identify opportunities for optimization. It has been specifically designed for use on large-scale systems including IBM Blue Gene and Cray XT, but is also well-suited for small- and medium-scale HPC platforms. Scalasca integrates runtime summaries with in-depth studies of concurrent behavior via event tracing. A distinctive feature is the ability to identify wait states that occur, for example, as a result of unevenly distributed workloads.
