In the past few decades, the demand for high-performance computing has been increasingly growing. These systems usually employ many processing elements working together via interconnection networks to solve complicated problems. Due to the efficiency and cost productivity, multistage interconnection networks (MINs) are recommended for use in such systems. At the same time, shuffle-exchange networks (SENs) have extensively been used as a suitable solution to multistage interconnection networks, given the size of their switching elements and simple configurations. In this paper, parallel SEN (PSEN) is proposed to enhance the reliability of these networks. Moreover, PSENs with one and two more stages (PSEN+ and PSEN+2) are utilized to optimize the reliability factor. The reliability analysis of the proposed network is performed through the reliability block diagram. According to the evaluation results, PSEN achieved higher reliability compared to SEN in different aspects of reliability, such as terminal, broadcast, and network. The proposed network also improves the cost-effectiveness in comparison with other MINs.

Parallel SEN：一种提高shuffle-exchange网络可靠性的新方法

在过去的几十年中，对高性能计算的需求日益增长。这些系统通常采用许多处理元件通过互连网络协同工作来解决复杂的问题。由于效率和成本生产率，建议在此类系统中使用多级互连网络 (MIN)。同时，鉴于其交换元件的大小和简单的配置，混洗交换网络 (SEN) 已被广泛用作多级互连网络的合适解决方案。在本文中，提出了并行 SEN (PSEN) 来提高这些网络的可靠性。此外，具有一级和二级（PSEN+ 和 PSEN+2）的 PSEN 用于优化可靠性因素。建议网络的可靠性分析是通过可靠性框图进行的。根据评估结果，PSEN在终端、广播、网络等不同方面的可靠性都比SEN具有更高的可靠性。与其他 MIN 相比，提议的网络还提高了成本效益。
