The Clang implementation of OpenMP® 4.5 now provides full support for the specification, offering the only open source option for targeting NVIDIA® GPUs. While using OpenMP allows portability across different architectures, matching native CUDA® performance without major code restructuring is an open research issue.In order to analyze the current performance, we port a suite of representative benchmarks,...
Hydra is a full-scale industrial CFD application used for the design of turbomachinery at Rolls Royce plc., capable of performing complex simulations over highly detailed unstructured mesh geometries. Hydra presents major challenges in data organization and movement that need to be overcome for continued high performance on emerging platforms. We present research in achieving this goal through the...
The Active Memory Cube (AMC) is a novel near-memory processor that exploits high memory bandwidth and low latency close to DRAM to execute scientific applications in an energy-efficient manner. Its energy efficiency is derived from a combination of its novel scalar-vector data-flow path combined with its simple control-flow path that required the development of a sophisticated compiler, co-designed...
