These switches form the leaf switch layer of the [Infiniband network](network/) fat tree topology. Nodes sharing the leaf switch can communicate most efficiently. Sharing the same switch prevents hops in the network and provides for unbiased, most efficient network communication. -Nodes sharing the same switch may be selected via the PBS resource attribute ibswitch. Values of this attribute are iswXX, where XX is the switch number. The node-switch mapping can be seen at [Hardware Overview](../hardware-overview/) section. +Nodes sharing the same switch may be selected via the PBS resource attribute ibswitch. Values of this attribute are iswXX, where XX is the switch number. The node-switch mapping can be seen at [Hardware Overview](hardware-overview/) section. We recommend allocating compute nodes of a single switch when best possible computational network performance is required to run the job efficiently:
