D7.3: Evaluation of Tools and Techniques for Future Exascale Systems

PRACE-5IP Work Package 7 (WP7) ‘Applications Enabling and Support’ enables support for High Performance Computing (HPC) applications codes to ensure that they effectively exploit multi-petaflop systems and future PRACE Exascale systems. Within WP7, Task 7.2 ‘Preparing for PRACE Exascale Systems’ looks ahead to future European exascale systems and investigates the tools and techniques that are developed to improve the performance and efficiency of applications that will run on these systems. This deliverable reports on the exploitation of state-of-the-art HPC tools and techniques developed in different European FET-HPC projects and applies them for developing, analysing and optimising the application codes. The application codes were selected with a focus on the European scientific and engineering research communities by working with European Centres of Excellence (CoEs). Much of the work reported in this deliverable is an extension to the work carried out in PRACE-4IP Task 7.2a as reported in D7.4 ‘Evaluation of Tools and Techniques for Future Exascale Systems’ and in PRACE-3IP WP7 as reported in D7.2.1 ‘A Report on the Survey of HPC Tools and Techniques’
