在本文中，我们报告了我们的“Iridis-PI”集群，它由Raspberry PI Model B节点组成，每个节点都配备了一个700 MHz的ARM处理器、256Mbit的RAM和一个用于本地存储的16GiB SD卡。该集群具有许多传统的基于数据中心的集群所不具备的优势，包括低总功耗、体积小、重量轻、易于携带、经济实惠以及被动的环境冷却。我们认为，这些属性使IRIDIS-PI非常适合教育应用程序，在教育应用程序中，它提供了一个低成本的起点，以启发和使学生理解和应用高性能计算和数据处理，以应对复杂的工程和科学挑战。我们给出了对“Iridis-PI”计算能力和网络性能进行基准测试的结果。我们还认为，这种系统应该考虑在一些额外的专业应用领域，这些独特的属性可能被证明是有利的。我们认为，选择ARM CPU预示着在高性能集群中越来越多地采用低功耗、非PC兼容架构的趋势。
In this paper, we report on our "Iridis-Pi" cluster, which consists of 64 Raspberry Pi Model B nodes each equipped with a 700 MHz ARM processor, 256 Mbit of RAM and a 16 GiB SD card for local storage. The cluster has a number of advantages which are not shared with conventional data-centre based cluster, including its low total power consumption, easy portability due to its small size and weight, affordability, and passive, ambient cooling. We propose that these attributes make Iridis-Pi ideally suited to educational applications, where it provides a low-cost starting point to inspire and enable students to understand and apply high-performance computing and data handling to tackle complex engineering and scientific challenges. We present the results of benchmarking both the computational power and network performance of the "Iridis-Pi." We also argue that such systems should be considered in some additional specialist application areas where these unique attributes may prove advantageous. We believe that the choice of an ARM CPU foreshadows a trend towards the increasing adoption of low-power, non-PC-compatible architectures in high performance clusters.
