    Abstract: A network switch has a packet pulling architecture, and also supports packet pushing. In an example implementation, a device includes: an output buffer; a data crossbar connected to the output buffer; an input buffer connected to the data crossbar; an input queue; a request crossbar connected to the input queue; and an output queue. The input queue is configured to transfer a packet from the input buffer to the output buffer over the data crossbar in response to the packet being eligible for packet pushing, and to send a push request in parallel with transferring the packet to the output buffer. The output queue is configured to receive the push request from the input queue over the request crossbar, and to control reading of the packet from the output buffer in response to granting the push request

    Abstract: Systems and methods are provided for implementing encryption of data-in-motion and/or otherwise stored data using a key server and a secure enclave of a Network Interface Card (NIC). The NIC acts as a passthrough between the client device and the shared infrastructure of the supercomputer system to help ensure data security in a massively scaled and distributed system. For example, in response to an enrollment process that stores a decrypted key in the secure enclave of a NIC, the NIC can receive a data packet from a client device. The NIC can transmit a key request to a key server that includes an encrypted key corresponding to the decrypted key. The key server can look up the previously stored private/public key pair to authenticate the NIC. The key server can provide private/public key pair to the NIC to allow the NIC to later encrypt data-in-motion.

    Abstract: System and methods are described for providing adaptive routing in the presence of persistent flows. Switches in a fabric have the capability to establish flow channels. Switches can adaptively route flows, while monitoring transmission characteristics of the flows channels to identify whether any flows are experiencing congestion towards a destination. In response to detecting congestion, it can be further determined whether the flow is related to a source of congestion, or alternative the flow is a victim of congestion. Flows that are a source of congestion have their routing constrained to prevent congestion from propagating. For example, new packets of a flow that is a source of congestion may be forced to only take the path of the data transmission that detected said congestion (preventing congestion from spreading). Alternatively, victims of congestion do not have their routing constrained, and packets can take any path as permitted by adaptive routing.
