DESIGNING STRATEGIES TO IMPLEMENT PARALLEL DISCRETE EVENT SYSTEM SPECIFICATION ALGORITHMS

Abstract:
Parallel Discrete Event System Specification (P-DEVS) algorithms have emerged as powerful tools for modeling and simulating complex systems with discrete event dynamics. These algorithms enable the efficient execution of simulations by distributing the computational workload across multiple processing units. However, designing strategies for implementing P-DEVS algorithms to leverage parallelism effectively remains a challenging task.

This paper presents a comprehensive examination of designing strategies to implement P-DEVS algorithms in parallel computing environments. The study focuses on identifying key considerations and techniques that can enhance performance and scalability while maintaining model correctness and synchronization.

The first aspect addressed in this paper is the decomposition of the P-DEVS model into independent modules that can be executed concurrently. Various decomposition techniques, such as spatial and temporal partitioning, are discussed along with their benefits and limitations. Additionally, load balancing methods are explored to ensure an equitable distribution of computational tasks among processing units.

Another crucial aspect covered in this study is synchronization mechanisms for maintaining the correct order of events in the simulation. Different synchronization strategies, including conservative and optimistic approaches, are examined, and their suitability for parallel execution is evaluated. The paper also discusses the trade-offs between synchronization overhead and simulation accuracy.

Furthermore, this research investigates communication and data management strategies in P-DEVS algorithms. Efficient inter-process communication mechanisms, such as message passing and shared memory, are analyzed to minimize communication overhead and ensure consistency in simulation results. Data management techniques, including data partitioning and replication, are explored to optimize memory usage and reduce data access latency.

Finally, the paper presents a comparative analysis of existing parallelization frameworks and libraries that can facilitate the implementation of P-DEVS algorithms. The evaluation considers factors such as ease of use, scalability, fault tolerance, and support for various parallel architectures.

The findings of this research provide valuable insights into designing effective strategies for implementing P-DEVS algorithms in parallel computing environments. The proposed strategies can enable researchers and practitioners to leverage the benefits of parallelism and achieve efficient and scalable simulations of complex systems. The study also identifies areas for further research and improvement in the field of parallel discrete event simulation.
