A Performance Analysis of Simple Runtime System for Actor Programming in C++

TL;DR

This paper introduces Templet, a high-performance C++ runtime system for actor programming, and compares its performance with OpenMP and Akka across numerical heat equation solutions.

Contribution

The paper presents Templet, a lightweight C++11-based actor runtime system, and evaluates its performance against existing frameworks in high-performance computing applications.

Findings

Templet outperforms OpenMP in the tested applications.

Templet's performance is comparable to Java's Akka.

The system demonstrates efficient actor management in C++.

Abstract

In this paper, we propose the Templet -- a runtime system for actor programming of high performance computing in C++. We provide a compact source code of the runtime system, which uses standard library of C++11 only. We demonstrate how it differs from the classic implementations of the actor model. The practical significance of the Templet was examined by comparative study on the performance of three applications: the reference code in C++, managed by the OpenMP; the actor code in C++, managed by the Templet; the actor code in Java, managed by the Akka. As a test problem we used a numerical algorithm for solving the heat equation.
