Abstract: Technologies for medium grained adaptive routing include one or more managed network devices coupled to one or more computing nodes via high-speed fabric links. A computing node may transmit a data packet including a destination local identifier (DLID) that identifies the destination computing node. The managed network device determines a static destination port based on the DLID, and determines whether the static destination port is congested. If congested, the managed network device determines a port group based on the DLID and selects a dynamic destination port from the port group. The port group may include two or more destination ports of the managed network device, and port groups may overlap. Port groups may be described by port masks stored in a port group table. The port groups and mappings between DLIDs and port groups may be configured by a fabric manager. Other embodiments are described and claimed.
