Scalasca 2.1 released

Aug 29, 2014: The Scalasca 2.1 release is available!

Scalasca is a software tool that supports the performance optimization of parallel programs by measuring and analyzing their runtime behavior. The analysis identifies potential performance bottlenecks - in particular those concerning communication and synchronization - and offers guidance in exploring their causes. It has been specifically designed for use on large-scale systems including IBM Blue Gene and Cray XT (and successors), but is also well-suited for small- and medium-scale HPC systems.

Unlike the Scalasca 1.x release series, Scalasca 2.1 is based on the community instrumentation and measurement infrastructure Score-P, which is jointly developed by a consortium of partners from Germany and the US. This significantly improves interoperability with other performance analysis tool suites such as Vampir and TAU due to the usage of the two common data formats CUBE4 for profiles and the Open Trace Format 2 (OTF2) for event trace data.
