Interconnect

Shaheen III is based on HPE/CRAY’s High Speed Network (HSN) Slingshot 11 interconnect technology. Slingshot is a modern highly scalable connectionless high-performance remote direct memory access (RDMA) interconnect that delivers very high bandwidth, and low latency.

The Slingshot Interconnect is based on leading edge enhanced Ethernet technology that supports industry leading raw bandwidth (200Gbps links) coupled with many advanced features including:

• Fine grain adaptive routing

• Congestion management

• QoS features

Slingshot 64 port high switch radix is used on Shaheen III, with 16 switches group per compute cabinet interconnected in a two-level Dragonfly topology.
