Package scalasca

Toolset for performance analysis of large-scale parallel applications

http://www.scalasca.org/


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.

Scalasca targets mainly scientific and engineering applications based
on the programming interfaces MPI and OpenMP, including hybrid
applications based on a combination of the two. The tool has been
specifically designed for use on large-scale systems, but is also well
suited for small- and medium-scale HPC platforms.
