Cost performance is one of the essential perspectives in designing and building parallel processing systems. Building a high-performance parallel processing system at a low cost is complicated work. Still, the recent development of computer and network technology provides a foundation for a rapid increase in the cost-performance ratio. This study verified whether the Raspberry Pi 4 clusters could show scalability and performance similar to other cluster systems from the cost-performance viewpoint. To evaluate the performance, we build a cluster system with 16 Raspberry Pi 4s and a high-speed network switch and perform the HPL benchmark. The experiment showed that the Raspberry Pi 4-based cluster system has parallel scalability according to cluster size and similar processing performance to other parallel processing systems. Therefore, it can expect that a cluster system with a low-cost processing device such as Raspberry Pi 4 could be applied to the high-performance cluster system.
