In this position paper, we discuss two relevant topics:(i) generic multiscale computing on
emerging exascale high-performing computing environments, and (ii) the scaling of such …

This short contribution introduces a theme issue dedicated to 'Multiscale modelling,
simulation and computing: from the desktop to the exascale'. It holds a collection of articles …

In the last few decades, multiscale modelling has emerged as one of the dominant
modelling paradigms in many areas of science and engineering. Its rise to dominance is …

We expect that multiscale simulations will be one of the main high performance computing
workloads in the exascale era. We propose multiscale computing patterns as a generic …

We argue that, despite the fact that the field of multiscale modelling and simulation has
enjoyed significant success within the past decade, it still holds many open questions that …

Multiscale problems naturally pose severe challenges for computational science and
engineering. The smaller scales must be well resolved over the range of the larger scales …

The development of an exascale computing capability with machines capable of executing
O (10 18) operations per second by the end of the decade will be characterized by …

As predicted by Gordon E. Moore in 1965, the performance of computer processors
increased at an exponential rate. Nevertheless, the increases in computing speeds of single …

This discussion represents an initial assessment of the scientific advancements that will
become plausible in the era of exascale computing and the profound challenges we face in …

We present a concise and comprehensive review of research communities which perform
multiscale computing. We provide an overview of communities in a range of domains, and …
