The predecessor of Scalasca, from which Scalasca evolved, is known by the name of KOJAK.

Definition

Scalasca is an open-source 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 including IBM Blue Gene and Cray XT, but is also well suited for small- and medium-scale HPC platforms.

Discussion

Introduction

Driven by growing application requirements and accelerated by current trends in microprocessor design, the number of processor cores on modern supercomputers is expanding from...
