Podcast: Slingshotting to Exascale

In this podcast, the Radio Free HPC team looks at the Cray Slingshot interconnect that will power all three of the first Exascale supercomputers in the US. “At the heart of this new interconnect is their innovative 64 port switch that provides a maximum of 200 Gb/s per port and can support Cray’s enhanced Ethernet along with standard Ethernet message passing. It also has advanced congestion control and quality of service modes that ensure that each job gets their right amount of bandwidth.”
