43 Years of Actors: a Taxonomy of Actor Models and Their Key Properties

The Actor Model is a message passing concurrency model that avoids common concurrency issues such as low-level data races and deadlocks by construction. This has made the Actor Model an interesting concurrency model that has been used in various concurrency settings both in research as well as in industry, ranging from exploiting concurrency in massively parallel workstations to expressing communication between different nodes in a distributed setting. Since its inception in the 70s researchers have explored a plethora of variations on the Actor Model. This paper presents a brief history of the Actor Model throughout those years. The goal of this paper is not to provide an exhaustive overview of every actor system in existence but rather to give an overview of some of the key languages and libraries that influenced the design and rationale of other actor systems. This paper therefore shows that most actor languages can be roughly classified into four families and list some of the key properties along which they can be evaluated.

Practical Hardware Considerations for the Design of Hybrid Precoding Systems

  • Rulikowski P.

In this paper we describe practical implications of employing communication schemes with analog beamforming networks (ABFN). Specifically, we formulate realistic constraints for standard ABFN based on the S-parameters of the hardware components involved in their implementation. We concentrate on flexible fully-connected ABFN and Butler networks for im- plementing the discrete ...

Microfluidic systems have been proposed as potential solutions for the cooling of next-generation Integrated Circuits (ICs) and Photonics Integrated Circuits (PICs). For PICs, integration of microfluidics may enable greater laser-bar array densities and, consequently, greater transmission bandwidth. To cool the micrometer scale hot-spots produced by the laser-bars, a passively actuated ...
