I've seen nothing showing that slingshot has any particular advantage over IB for HPC. Sure HPE pushes slingshot (an HPE interconnect) over giving bags of money to Nvidia, but that's a business decisions. Eagle (the #4 cluster on the list) is Infiniband NDR. I believe 306 of the top 500 clusters used Infiniband. Pretty sure the advance topologies like dragonfly are supported on IB as well as Slingshot. From what I can tell slingshot is much like ultra ethernet, trying to take the best of IB and ethernet and making a new standard. From what I can tell slingshot 11 latency is much like I got with omnipath/pathscale way back when dual core opterons were the cutting edge.
