Sandr Heterogeneous many-core systems constitute a viable approach for coping with power constraints in modern computer architectures and can now be found across the whole computing landscape ranging from mobile(More)
Heterogeneous many-core architectures offer a way to cope with energy consumption limitations of various computing systems from small mobile devices to large data-centers. However, programmers typically must consider a large diversity of architectural information to develop efficient software. In this paper we present our ongoing work towards a Platform(More)
The Intel Threading Building Blocks (TBB) C++ library introduced task parallelism to a wide audience of application developers. The library is easy to use and powerful, but it is limited to shared-memory machines. In this paper we present HyPHI, a novel library for the Intel Xeon Phi coprocessor for building applications which execute using a hybrid(More)
With the increasing architectural diversity of many-core architectures the challenges of parallel programming and code portability will sharply rise. The EU project PEPPHER addresses these issues with a component-based approach to application development on top of a taskparallel execution model. Central to this approach are multi-architectural components(More)
In this paper we present ongoing work towards a programming framework for heterogeneous hardware- and software environments. Our framework aims at improving programmability and portability for heterogeneous many-core systems via a Platform Description Language (PDL) for expressing architectural patterns and platform information. We developed a prototypical(More)
The introduction of Intel R © Xeon Phi TM coprocessors opened up new possibilities in development of highly parallel applications. The familiarity and flexibility of the architecture together with compiler support integrated into the Intel C++ Composer XE allows the developers to use familiar programming paradigms and techniques, which are usually not(More)
The extreme scale, complexity and performance variability of future high performance computing systems pose many new challenges to parallel programming models and runtime systems. The Open Community Runtime (OCR) is a recent effort for a task-based runtime system for extreme scale parallel systems. We have implemented the OCR specification in a(More)
Parallel architectures with node-level accelerators promise significant performance improvements over conventional homogeneous systems. To cope with the increased complexity of programming such systems various pattern-based programming libraries have become available. In this paper we present our work on providing autotuning capabilities for two runtime(More)
