+the programming interfaces MPI and OpenMP, including hybrid applications based
+on a combination of the two.  Unlike Scalasca 1.x, the Scalasca 2.x release
+series is based on the community instrumentation and measurement infrastructure
+Score-P.  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.")
