Scalable performance-analysis toolsetfor parallel codes • Suitable for wide range of HPC platforms • Analysis modes • Performance overview on call-path level via runtime summarization • In-depth study of communication & synchronization via automatic trace analysis • Identification of wait states • Supported programming models • MPI 2.2 including RMA analysis • OpenMP (basic features) • Available under the New BSD license • http://www.scalasca.org/ • Installed at LLNL for TLCC, up, and BG/L(unsupported test version) Joint project of

  2. Libra: Scalable Load Balance Analysis Running Application • Libra is a tool for quickly monitoring load-balance • Handles applications with large numbers of time steps • Handles time-evolving patterns • Small, phased effort profiles displayed intuitively in surface plot • Can observe different phases of code separately • Scalable wavelet-based compression enables use at scale EffortInstrumentation ScalableCompression ScalableVisualization
