supercomputer to be based on Arm CPUs that have been optimised specifically for HPC …

In recent years the computer processors underpinning the large, distributed, workhorse
computers used to solve the Boltzmann transport equation have become ever more parallel …

Recent generations of general-purpose central processing units (CPUs) for the high-
performance segment have had to adopt new approaches in order to deliver increasing …

In this paper we investigate the effects of wide vector instructions on modern processor
caches. On the one hand, contemporary processors have large, highly associative caches …

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

The problem of efficiently feeding processing elements and finding ways to reduce data
movement is pervasive in computing. Efficient modeling of both temporal and spatial locality …

The full assembly of the stiffness matrix in finite element codes can be prohibitive in terms of
memory footprint resulting from storing that enormous matrix. An optimisation and work …
