Abstract The Finite-Difference Time-Domain (FDTD) method is a popular numerical
modelling technique in computational electromagnetics. The volumetric nature of the FDTD …

The best hope for reducing long-standing global climate model biases is by increasing
resolution to the kilometer scale. Here we present results from an ultrahigh-resolution non …

In this article, we present Ginkgo, a modern C++ math library for scientific high performance
computing. While classical linear algebra libraries act on matrix and vector objects, Ginkgo's …

The term “performance portability” has been informally used in computing to refer to a variety
of notions which generally include:(1) the ability to run one application across multiple …

Many scientific codes consist of memory bandwidth bound kernels. One major advantage of
many-core devices such as general purpose graphics processing units (GPGPUs) and the …

The abstraction of a shared memory space over separate CPU and GPU memory domains
has eased the burden of portability for many HPC codebases. However, users pay for the …

oneAPI is an open standard for a software platform built around SYCL 2020 and accelerated
libraries such as oneMKL as well as low-level building blocks such as oneAPI Level Zero …

Stencil computation is one of the most widely-used compute patterns in high performance
computing applications. Spatial and temporal blocking have been proposed to overcome the …

Graphics processors are widely utilized in modern supercomputers as accelerators. Ability to
perform efficient parallelization and low-level allow scientists to greatly boost performance of …
