Using analog computers in today's largest computational challenges

Abstract

Analog computers perceive a revival as a feasible technology platform for low precision, energy efficient and fast computing. We quantify this statement by measuring the performance of a modern analog computer and comparing it with traditional digital processors. General statements are made about ordinary and partial differential equations. As an example for large scale scientific computing applications, computational fluid dynamics are discussed. Several models are proposed which demonstrate the benefits of analog and digital-analog hybrid computing.
