Priority Programme "Software for Exascale Computing" Trilateral Call for Proposals - 2nd funding period
Deutsche Forschungsgemeinschaft (DFG)
The Senate of the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) has established the Priority Programme "Software for Exascale Computing" (SPPEXA, SPP 1648) in 2011. The programme is designed to run for six years; the present call invites proposals for the second three-year funding period 2016 to 2018 and is now opening up to foster international collaboration. The call is intended to support collaborative projects of bi- or trilateral research teams, bringing together researchers from France (ANR), Germany (DFG), and Japan (JST).

Idea and Objectives
The Priority Programme addresses fundamental research on the various aspects of High-Performance Computing (HPC) software, which is particularly urgent against the background that we are currently entering the era of ubiquitous massive parallelism. Exascale performance, i.e. 1018 FLOP/s, and beyond will require massive parallelism realised by many-core processors assembled to systems beyond 107 processing units. With this, several challenges come along, such as efficient treatment of I/O, resilience or load balancing. Mastering the various challenges related to this paradigm shift from sequential or just moderately parallel to massively parallel processing will be the key to any future capability computing application - e.g., large-scale simulations - at exascale, but it will also be crucial for learning how to effectively and efficiently deal with commodity systems of the day after tomorrow for smaller-scale or capacity computing tasks - and it is the overall scientific objective of SPPEXA.

To this end, SPPEXA re-connects several relevant sub-fields of computer science with the needs of Computational Science and Engineering (CSE) and HPC. In the first funding period, SPPEXA established the framework for a much closer cooperation and a much more co-design-driven approach - instead of a merely service-driven collaboration of groups focussing on fundamental HPC methodology (computer science or mathematics) on the one hand with those working on science applications and providing the large codes (science and engineering) on the other hand. Topically, SPPEXA will continue to drive research towards extreme-scale computing in six areas or research directions:
- computational algorithms
- system software and runtime libraries
- application software
- data management and exploration
- programming
- software tools

Hardware peak performance is ever increasing, exascale systems are currently predicted for around 2020, and there is a world-wide consensus that a "racks without brains" strategy cannot allow the science communities to exploit the huge potential of the computational approach in a massively parallel world. Against this background, SPPEXA provides an ideal environment for bundling research activities on a national as well as, via intra-project or inter-project collaboration, an international level and for enabling the participating groups to significantly advance the state of the art in HPC software technology.

Proposals for the second three-year SPPEXA funding period are now invited. All proposals must be written in English and submitted via DFG's electronic proposal processing system "elan" by:
31 January 2015, 24:00 CET
