Using analog computers in today's largest computational challenges
Abstract. Analog computers can be revived as a feasible technology platform for low
precision, energy efficient and fast computing. We justify this statement by
measuring the performance of a modern analog computer and comparing it with
that of traditional digital processors. General statements are made about the solution
of ordinary and partial differential equations.
Computational fluid dynamics are discussed as an example of large scale scientific
computing applications. Several models are proposed which demonstrate the benefits
of analog and digital-analog hybrid computing.
