Hands on with OpenMP4.5 and Unified Memory: Developing Applications for IBM’s Hybrid CPU?+?GPU Systed GPUs and manage on-node memories and application data. Through code samples we provide application developers with numerous options for memory management and data management. We consider simple functions using arrays and also complex and nested data structures.

Hands on with OpenMP4.5 and Unified Memory: Developing Applications for IBM’s Hybrid CPU?+?GPU SysteSpecifically, we focus on nested parallelism and Unified Memory as key elements for efficient system-wide programming of CPU and GPU resources of OpenPOWER. We give implementation details using code samples and we discuss limitations of the presented approaches.

Porting VASP from MPI to MPI+OpenMP [SIMD]rent calling contexts as well as whole function vectorization. In addition to outlining design decisions made throughout the code transformation process, we will demonstrate the effectiveness of the code adaptations using different compilers (GNU, Intel) and target platforms (CPU, Intel Xeon Phi (KNL)).

The Productivity, Portability and Performance of OpenMP 4.5 for Scientific Applications Targeting Inion and neutral particle transport, using modern compilers with OpenMP support. The results show that while current OpenMP implementations are able to achieve good performance on the breadth of modern hardware for memory bandwidth bound applications, our memory latency bound application performs less consistently.
