Epirust: Towards a Framework for Large-Scale Agent-Based Epidemiological Simulations Using Rust Language

EasyChair Preprint no. 4160

Abstract

To implement large-scale agent-based simulations, developers historically relied on C and C++ due to performance, while struggling to deal with tedious explicit memory management. This struggle translates into software defects and lower developer productivity. More recently, desire to harness multi-core systems via concurrent software complicates design and implementation when memory is shared among compute cores. When we faced this situation, we were looking for a system programming languages as fast as C and C++ but without caveats around memory management. Between Go and Rust, we chose Rust language which guarantees safety in memory management even for concurrency, without a run-time or garbage collector. In this paper, we intend to share our experience with Rust to build a framework for agent-based epidemiological simulations. Our experiments show promising results for a million agents, all running on commodity-class hardware. Key outcomes of this whole exercise are: 1. Performance 2. Flexibility 3. Robustness.
