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, but is also well-suited for small- and medium-scale HPC systems.
This release provides a number of significant fixes. Therefore, we strongly encourage all users to update their installations.
See the Scalasca download page for detailed information.
