- 3491418.3530773 description "ABSTRACT The Slingshot interconnect designed by HPE/Cray is becoming more relevant in High-Performance Computing with its deployment on the upcoming exascale systems. In particular, it is the interconnect empowering the first exascale and highest-ranked supercomputer in the world, Frontier. It offers various features such as adaptive routing, congestion control, and isolated workloads. The deployment of newer interconnects raises questions about performance, scalability, and any potential bottlenecks as they are a critical element contributing to the scalability across nodes on these systems. In this paper, we will delve into the challenges the slingshot interconnect poses with current state-of-the-art MPI libraries. In particular, we look at the scalability performance when using slingshot across nodes. We present a comprehensive evaluation using various MPI and communication libraries including Cray MPICH, OpenMPI + UCX, RCCL, and MVAPICH2-GDR on GPUs on the Spock system, an early access cluster deployed with Slingshot and AMD MI100 GPUs, to emulate the Frontier system." assertion.
