“…Notable examples are the compiler directive-based approaches OpenMP [3] and OpenACC [13], the C++ template-based approaches Kokkos [6] and RAJA [1], and language extensions such as OpenCL [21]. Many of these have been the target of studies looking at performance portability across heterogeneous platforms [5,7,9,10,15,17,23].…”

In June 2022, Frontier became the first Supercomputer to "officially" break the ExaFLOP/s barrier on LINPACK, achieving a peak performance of 1.1×10 18 floating-point operations per second using AMD Instinct accelerators. Developing high performance applications for such platforms typically requires the adoption of vendor-specific programming models, which in turn may limit portability. SYCL is a high-level, singlesource language based on C++17, developed by the Khronos group to overcome the shortcomings of those vendor-specific HPC programming models. In this paper we present an initial study into the SYCL parallel programming model and its implementing compilers, to understand its performance and portability, and how this compares to other parallel programming models. We use three major SYCL implementations for our evaluation -Open SYCL (previously hipSYCL), DPC++, and ComputeCpp -on a range of CPU and GPU hardware from Intel, AMD, Fujitsu, Marvell, and NVIDIA. Our results show that for a simple finite difference mini-application, SYCL can offer competitive performance to native approaches, while for a more complex finite-element mini-application, significant performance degradation is observed. Our findings suggest that development work is required at the compilerand application-level to ensure SYCL is competitive with alternative approaches.

“…CloverLeaf is a Lagrangian-Eulerian explicit hydrodynamics mini application, with both 2D and 3D variants. BookLeaf is an unstructured compressible hydrodynamics proxy application, its performance and portability was evaluated in detail by Law et al [102,84], considering OpenMP, CUDA, Kokkos, and RAJA, calculating the aforementioned portability metric as well. The authors evaluate performance on a ).…”

Hardware trends over the last decade show increasing complexity and heterogeneity in high performance computing architectures, which presents developers of CFD applications with three key challenges; the need for achieving good performance, being able to utilise current and future hardware by being portable, and doing so in a productive manner. These three appear to contradict each other when using traditional programming approaches, but in recent years, several strategies such as template libraries and Domain Specific Languages have emerged as a potential solution; by giving up generality and focusing on a narrower domain of problems, all three can be achieved. This paper gives an overview of the state-of-the-art for delivering performance, portability, and productivity to CFD applications, ranging from highlevel libraries that allow the symbolic description of PDEs to low-level techniques that target individual algorithmic patterns. We discuss advantages and challenges in using each approach, and review the performance benchmarking literature that compares implementations for hardware architectures and their programming methods, giving an overview of key applications and their comparative performance.

“…This is to ensure a fair comparison between the original mini-application runtime, and the runtime of the mini-application with WDS integration. 1) BookLeaf: BookLeaf [19], [22] solves the compressible Euler equations on an unstructured grid using an Arbitrary Lagrangian-Eulerian (ALE) formulation. These equations describe the dynamics of inviscid fluids, and are used widely to solve many problems in science and engineering.…”
