ompRewbishopO

ompRewbishopO is an open‑source parallel computing library that implements a refined version of OpenMP directives for the Rust programming language. It was first released in 2023 by the Rewbishop Research Group at the University of Bergen, which aimed to bring high‑performance shared‑memory programming capabilities to the Rust ecosystem. The library builds upon the existing rust‑omp crate but introduces stricter type safety guarantees, support for dynamic work sharing, and a lightweight scheduler that integrates with the Rayon data‑parallelism framework.

Key features of ompRewbishopO include support for parallel loops with reduction, critical sections, and task constructs that adhere closely to the OpenMP 5.0 specification. It also provides macros for dynamic parallelism and a runtime configuration API that allows developers to tune thread pool sizes and affinity settings. The library is distributed under the MIT license and is supported on Linux, macOS, and Windows platforms, with ongoing work to improve support for ARM architectures.

Academic and industrial users have adopted ompRewbishopO in computational fluid dynamics, signal processing, and machine‑learning workloads to leverage Rust’s zero‑cost abstractions while maintaining performance comparable to native OpenMP implementations. Reviews in the Journal of Parallel Computing highlighted the library’s ease of integration into existing Rust codebases, though some users noted the learning curve associated with Rust’s ownership model.
