Schedulability Analysis of OpenMP Applications Under Heuristic Task-To-Thread Mapping

Authors: Mohammad Samadi, Tiago Carvalho, Luís Miguel Pinho, and Sara Royuela

Published in: OASIcs, Volume 140, 7th Workshop on Next Generation Real-Time Embedded Systems (NG-RES 2026)

Abstract
Task-to-thread mapping is a key process in parallel applications to achieve the best possible performance. This process is even more challenging when it is required to meet the schedulability and timing requirements of critical systems. In these systems, mapping tasks to threads is usually carried out using static scheduling (i.e., offline mapping) to improve system schedulability, with several approaches being presented in the literature. Nevertheless, there has been little analysis on the impact that these static mapping approaches have on the schedulability of applications exploiting OpenMP, a model increasingly seen as a suitable mechanism to leverage the potential of parallel and heterogeneous processor architectures. This paper, therefore, performs a throughout evaluation of the recently presented heuristic task-to-thread mapping working with different heuristics through allocation and dispatching phases, compared with state-of-the-art, in terms of schedulability. This process is performed using a state-of-the-art schedulability analysis methodology through an integration of our simulator and an existing schedulability toolset. This evaluation allows for identifying the static heuristic mapping approaches that achieve tighter schedulability analysis than other methods in the literature.

HiPART: High-Performance Technology for Advanced Real-Time Systems

Authors: Sara Royuela, Adrian Munera, Chenle Yu, and Josep Pinot

Published in: OASIcs, Volume 127, 16th Workshop on Parallel Programming and Run-Time Management Techniques for Many-Core Architectures and 14th Workshop on Design Tools and Architectures for Multicore Embedded Computing Platforms (PARMA-DITAM 2025)

Abstract
Cyber-physical systems (CPS) attempt to meet real-time and safety requirements by using hypervisors that provide isolation via virtualisation and Real-Time Operating Systems that manage the concurrency of system tasks. However, the operating system’s (OS) decisions may hinder the efficiency of tasks because it needs more awareness of their specific intricacies. Hence, one critical limitation to efficiently developing CPSs is the lack of tailored parallel programming models that can harness the capabilities of advanced heterogeneous architectures while meeting the requirements integral to CPSs, such as real-time behaviour and safety requirements. While conventional HPC languages, like OpenMP and CUDA, cannot accommodate critical non-functional properties, safety languages, like Rust and Ada, are limited in their capabilities to exploit complex systems efficiently. On top of that, accessibility to the programming task is essential to making the system usable to different domain experts. HiPART tackles these challenges by developing a comprehensive framework holistically addressing efficiency, interoperability, reliability, and sustainability. The HiPART framework, based on OpenMP, provides tailored support for (1) real-time behaviour and safety requirements and (2) the efficient exploitation of advanced parallel and heterogeneous processor architectures. This support is exposed to users through extensions to the OpenMP specification and its implementation in the LLVM framework, including the compiler and the OpenMP runtime library. With this framework, HiPART will contribute to realising more capable and reliable autonomous systems across various domains, from autonomous mobility to space exploration.
