Hardware trends over the last decade show increasing complexity and heterogeneity in high
performance computing architectures, which presents developers of CFD applications with …

Across embedded, mobile, enterprise, and high performance computing systems, computer
architectures are becoming more heterogeneous and complex. This complexity is causing a …

In this study we introduce EMPIRE-PIC, a finite element method particle-in-cell (FEM-PIC)
application developed at Sandia National Laboratories. The code has been developed in …

Performance portability is becoming more-and-more important as next-generation high
performance computing systems grow increasingly diverse and heterogeneous. Several …

Large scale simulations are a key pillar of modern research and require ever-increasing
computational resources. Different novel manycore architectures have emerged in recent …

We explore the performance and portability of the high-level programming models: the
LLVM-based Julia and Python/Numba, and Kokkos on high-performance computing (HPC) …

System and node architectures continue to diversify to better balance on-node computation,
memory capacity, memory bandwidth, interconnect bandwidth, power, and cost for specific …

This paper will evaluate the progress being made on achieving performance portability by a
sub-set of ECP applications, or their related mini-apps, across a diverse spectrum of …

The phrase “performance portability” is commonly used, but may mean different things to
different people. Develo** a better appreciation of the needs of different software …

From edge to exascale, computer architectures are becoming more heterogeneous and
complex. The systems typically have fat nodes, with multicore CPUs and multiple hardware …
