Apparatuses, systems, and techniques to perform signal processing operations in a fifth generation (5G) new radio (NR) network using one or more parallel processing units (PPUs). In at least one embodiment, one or more PPUs implement signal processing in a baseband unit (BBU) performing 5G NR physical layer operations in a communication network.

Accelerated parallel processing of 5G NR signal information

A cluster compute server includes nodes coupled in a network topology via a fabric that source routes packets based on location identifiers assigned to the nodes, the location identifiers representing the locations in the network topology. Host interfaces at the nodes may be associated with link layer addresses that do not reflect the location identifier associated with the nodes. The nodes therefore implement locally cached link layer address translations that map link layer addresses to corresponding location identifiers in the network topology. In response to originating a packet directed to one of these host interfaces, the node accesses the local translation cache to obtain a link layer address translation for a destination link layer address of the packet. When a node experiences a cache miss, the node queries a management node to obtain the specified link layer address translation from a master translation table maintained by the management node.

Distributed packet switching in a source routed cluster server

A cluster compute server comprises a fabric interconnect, a first node coupled to the fabric interconnect and comprising a network interface controller coupleable to an external network, and a second node coupled to the fabric interconnect and comprising a fabric interface to provide a set of one or more virtual network interface controllers representing the network interface controller of the first node. The one or more virtual network interface controllers each appear as a local network interface controller to software executed at the second node. The first node is to emulate one or more link aggregation partners for the set of one or more virtual network interface controllers.

Link aggregation emulation for virtual NICs in a cluster server

A cluster compute server comprises a set of one or more compute nodes, each compute node instantiating at least one virtual network interface controller representing a network interface controller of a primary network node remote to the compute node and appearing as a local network interface controller to the compute node. A first network node comprising a network interface controller coupleable to an external network operates as the primary network node for the set. The first network node emulates link aggregation partners for virtual network interfaces of the set based on first link state information maintained at the first network node. A second network node comprising a network interface controller coupleable to the external operates as a secondary network node for the set. The second network node maintains second link state information that mirrors the first link state information maintained at the first network node.
