D7.1.2: Final Report on Applications Enabling

Task T7.1 “Scaling and Optimisation of Applications Codes” in Work Package 7 of PRACE-3IP aims to provide application enabling support for the HPC applications which are important for the European researchers to ensure the applications can effectively exploit multi-petaflop systems. There were three activities in T7.1: T7.1.A Petascaling & Optimisation Support for Preparatory Access Projects: this activity provided code enabling and optimisation to European researchers as well as industrial projects to make their applications ready for Tier-0 systems. Projects can continuously apply for such services via the Preparatory Access Call Type C (PA C) with a cut-off every three months for evaluation of the proposals. Five Preparatory Access Calls have been carried out in PRACE-3IP and a total of 10 PA C projects have finished their work. The report focused on the optimization work and results gained by the completed projects in PRACE-3IP. The statistics about the PA C calls in PRACE-3IP as well as a description of the call organization itself is also included. The results of the completed projects have also been documented in white papers which were published on the PRACE-RI website. T7.1.B Applications Support for DECI Projects: this activity in PRACE-3IP continued providing the technical support to DECI projects on Tier-1 systems since August 2013 after the PRACE-2IP ended. 15 partner sites were involved providing 73 PMs in total for the DECI technical support. In the 2nd year of PRACE-3IP, 180 Technical Evaluations (TEs) were performed, 119 for DECI-11 and 61 for DECI-12 applications. Technical support was provided for 31 DECI-9 and 37 DECI-10 projects which started in PRACE-2IP and were continued in PRACE-3IP. Full support was provided for 52 DECI-11 projects, and the starting assistance was provided for the 34 DECI-12 projects. Application enabling support was provided for four of the DECI projects and the enabling work done are reported in this deliverable. T7.1.C Major socio-economic challenges and associated applications: this activity focused on enabling applications addressing key socio-economic challenges. The identified challenges included safe and environmental-friendly energy production, rational drug design, sustainable food supply, future aircraft transportation, ‘big data’ management and processing, understanding of climate change and natural environment protection. Eleven projects have been completed to address the given challenges and support over 20 recognised community codes. The enabling work focused on: application suites enabling for a multi-discipline modelling with coupling separate codes on the selected HPC platforms, improving computational kernels and scalable implementations. Following on the D7.1.1 in PRACE-3IP which reported on the identification of the challenges and codes, this deliverable includes the reporting on the completed projects as well as indications for future improvements and potential benefits for the application communities. Results and outcomes of these projects have also been presented with more technical details in the dedicated white papers
