Optimize the use of your IB NDR network

Miguel Terol Senior HPC Architect Lenovo Abstract: The new Infiniband NDR technology allow for bandwidths of up to 400 Gbps per host port. Although some applications use as much bandwidth as available, for many other these numbers are overkilling. We will present how to optimize your IB topology, leveraging Lenovo SharedIO concept for dense systems to allow up to 256 compute nodes in a single 1U IB switch. More information: https://hpckp.org/
