Existing OS techniques for homogeneous many-core systems make it simple for single and multithreaded applications to migrate between cores. Heterogeneous systems do not benefit so fully from this flexibility, and applications that cannot migrate in m

High throughput applications with real-time guarantees are increasingly relevant. For these applications, parallelism must be exposed to meet deadlines. Directed Acyclic Graphs (DAGs) are a popular and very general application model that can capture

Resilience for HPC applications typically is implemented as a CPU-based rollback-recovery technique. In this context, long running accelerator computations on GPUs pose a major challenge as these devices usually do not offer any means of interrupt. T

To address NUMA performance anomalies, programmers often resort to application specific optimizations that are not transferable to other programs, or to generic optimizations that do not perform well in all cases. Skeleton based programming models al

Running multiple parallel programs on multi-socket multi-core machines using commodity hardware is increasingly common for data analytics and cluster workloads. These workloads exhibit bursty behavior and are rarely tuned to specific hardware. This l

GPGPUs are a powerful and energy-efficient solution for many problems. For higher performance or larger problems, it is necessary to distribute the problem across multiple GPUs, increasing the already high programming complexity. In this article, we
