Konferensbidrag (refereegranskat)abstract
- The European FP7 project PEPPHER is addressing programmability and performance portability for current and emerging heterogeneous many-core architectures. As its main idea, the project proposes a multi-level parallel execution model comprised of potentially parallelized components existing in variants suitable for different types of cores, memory configurations, input characteristics, optimization criteria, and couples this with dynamic and static resource and architecture aware scheduling mechanisms. Crucial to PEPPHER is that components can be made performance aware, allowing for more efficient dynamic and static scheduling on the concrete, available resources. The flexibility provided in the software model, combined with a customizable, heterogeneous, memory and topology aware run-time system is key to efficiently exploiting the resources of each concrete hardware configuration. The project takes a holistic approach, relying on existing paradigms, interfaces, and languages for the parallelization of components, and develops a prototype framework, a methodology for extending the framework, and guidelines for constructing performance portable software and systems-including paths to migration of existing software-for heterogeneous many-core processors. This paper gives a high-level project overview, and presents a specific example showing how the PEPPHER component variant model and resource-aware run-time system enable performance portability of a numerical kernel. © 2012 The authors and IOS Press.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- The European participation in the next step fusion energy research project, ITER, is very broad with interests from all EU member states. To support the needed physics understanding and predictive capability for ITER discharges, a strong need to promote modelling technologies and access to computing resources on a pan-European basis exists. The EUFORIA project, EU Fusion for ITER Applications, sets out to support these needs by creating an e-Science environment, building on the existing European infrastructure and middleware environments and specifically introducing the developments towards a modelling platform for fusion being advanced within the European fusion community. The aim is to advance the physics modelling capability for ITER on a broadened European Scale. The EUFORIA approach and its different components are discussed here. © 2010 The authors and IOS Press.
