The requirements placed on computer architectures from modern computational workloads
have driven constant performance improvements. In the last 15 years, the largest source of …

Following the trend towards Exascale, today's supercomputers consist of increasingly
complex and heterogeneous compute nodes. To exploit the performance of these systems …

Abstract Hierarchical matrix (H-matrix), which is widely used in boundary element method
(BEM) and N-body simulations, is an approximated form to represent N× N correlations of N …

We provide efficient implementations of common Fast Multipole Method (FMM) tasks for
modern multi-core (Intel Xeon Haswell), many-core (Intel Xeon Phi Knights Landing) and …

Computational science is at the core of many scientific domains as much in academic
research than in industrial research and development. Computer simulations are used in a …

For many years, the stability of the architecture paradigm has facilitated the performance
portability of large HPC codes from one generation of supercomputers to another. The …
