Agate Topology

AgAgate is an Infiniband-connected high-performance computing cluster. It is a separate cluster from Mesabi and Mangi. Multi-node jobs will not span multiple clusters. However, both clusters share the same Primary Storage (home directories).



All the nodes in Agate have HDR100 Infiniband connections connected in a 2-level fat tree topology. Most multi-node jobs will not be substantially impacted by the placement on particular nodes. However, some large, multi-node MPI jobs may experience varied performance due to the placement on particular nodes.
