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.

Abstract: Technologies for fabric security include one or more managed network devices coupled to one or more computing nodes via high-speed fabric links. A managed network device enables a port and, while enabling the port, securely determines the node type of the link partner coupled to the port. If the link partner is a computing node, management access is not allowed at the port. The managed network device may allow management access at certain predefined ports, which may be connected to one of more management nodes. Management access may be allowed for additional ports in response to management messages received from the management nodes. The managed network device may check and verify data packet headers received from a compute node at each port. The managed network device may rate-limit management messages received from a compute node at each port. Other embodiments are described and claimed.

Abstract: Technologies for scalable local addressing 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 DLID may be 32, 24, 20, or 16 bits wide. The managed network device may determine whether the DLID is within a configurable multicast address space and, if so, forward the data packet to a multicast group. The managed network device may also determine whether the DLID is within a configurable collective address space and, if so, perform a collective acceleration operation. The number of top-most bits set in a multicast mask and the number of additional top-most bits set in a collective mask may be configured. Multicast LIDs may be converted between different bit lengths. Other embodiments are described and claimed.
