HPE Slingshot is a modern high-performance interconnect for HPC and AI clusters that delivers industry leading performance, bandwidth, and low latency for HPC, AI/ML, and data analytics applications. It is Cray's 8 generation interconnect architecture with unique and powerful innovations engineered from the silicon up to combine the best of a high-performance supercomputing-class interconnect with ethernet compatibility. This enables a unified high-performing cluster that delivers great performance on both traditional modeling and simulation codes alongside native sockets-based applications, and with direct Ethernet connectivity to storage without requiring gateway nodes. Beyond raw speed (25.6 Tbps of bidirectional bandwidth per switch and 200 Gbps endpoints), HPE Slingshot dramatically controls loaded latency, the true determinant of realized performance on tightly-coupled HPC and AI workloads. Innovative congestion management reduces tail latency and run-to-run execution time variability, and fine-grained adaptive routing ensures high utilization of the bandwidth available. With HPE Slingshot for HPC Clusters, the same interconnect in the world's most powerful supercomputers can now be deployed across a wide spectrum of HPC system sizes and configurations based on HPE Apollo and HPE ProLiant compute nodes. HPE Slingshot Highlights | High Bandwidth and Low Latency HPE Slingshot switches provide 25.6 Tbps of bi-directional bandwidth with 64 ports each capable of 200 Gbps, delivering high bandwidth and low latency simultaneously, overcoming traditional Ethernet approaches to buffering and error handling that create queueing latency that hinder low-latency RDMA applications. Automatic Congestion Management The HPE Slingshot network uniquely addresses the congestion challenges of short-lived, small packet flows typical in HPC applications. In hardware, each switch detects congestion, identifies its causes, and provides real-time feedback to its peers. The system distinguishes perpetrators from victims of injection and limits the injection rate from the perpetrator until congestion clears. Fine-Grained Adaptive Routing HPE Slingshot tracks real-time information on load across each switch-to-switch path, and dynamically re-routes traffic to balance load (rather than sticking only to a predetermined path) to improve network performance and bandwidth utilization. Uniquely, HPE Slingshot's adaptive routing decisions are made on a packet-by-packet basis for unordered traffic, or a flow-by-flow basis for protocols (like TCP/IP) requiring ordered delivery. Quality of Service HPE Slingshot supports highly configurable quality-of-service (QoS) that provide the ability to control how network bandwidth is allocated to different classes of traffic and applications.
