Tools for High Performance Computing 2013 : Proceedings of the 7th International Workshop on Parallel Tools for High Performance Computing September 2013 ZIH Dresden Germany Current advances in High Performance Computing (HPC) increasingly impact efficient software development workflows. Programmers for HPC applications need to consider trends such as increased core counts multiple levels of parallelism reduced memory per core and I O system challenges in order to derive well performing and highly scalable codes. At the same time the increasing complexity adds further sources of program defects. While novel programming paradigms and advanced system libraries provide solutions for some of these challenges appropriate supporting tools are indispensable. Such tools aid application developers in debugging performance analysis or code optimization and therefore make a major contribution to the development of robust and efficient parallel software. This book introduces a selection of the tools presented and discussed at the 7th International Parallel Tools Workshop held in Dresden Germany September 3 4 2013.
