Abstract: A system for facilitating RDMA transmit flow scheduling and pacing is disclosed. The system may determine a set of groups. The groups may be associated with a range of transmission rates. The system may determine a transmission rate of a queue pair. The system may assign the QP to a first group of the set of groups. The transmission rate of the QP may be within the range of transmission rates of the first group. The system may determine an available QP of at least one group from the set of groups. The system may schedule transmission, by an arbiter, of the available QP. The system may transmit, by the arbiter, a message associated with the available QP.

Abstract: A system includes a first integrated circuit package including a first group of one or more artificial intelligence processing units and a first chip-to-chip interconnect communication unit and a second integrated circuit package including a second group of one or more artificial intelligence processing units and a second chip-to-chip interconnect communication unit. The system also includes an interconnect between the first integrated circuit package and the second integrated circuit package, wherein the first chip-to-chip interconnect communication unit and the second chip-to-chip interconnect communication unit manage ethernet-based communication via the interconnect using a layered communication architecture supporting a credit-based data flow control and a retransmission data flow control.

Abstract: A system for adapting to a partially unhealthy network and bypassing failures associated with the network is provided. The system may enable determining a designated network path configured to transfer traffic data from a first communication device, via one or more network switches, to a second communication device. The system may enable determining at least one network failure, associated with the network path, causing at least a subset of the traffic data to be blocked along the network path. The system may enable determining one or more tracker windows associated with one or more other network paths that are available to transfer traffic content. The system may enable selecting at least one network path of the one or more other network paths to transfer the at least the subset of the traffic data to the second communication device.

Abstract: A system for Remote Direct Memory Access incast congestion management is provided. The system may access one or more receive work queue entities (RWQEs) associated with one or more send work queue entities (SWQEs), determine a transmission rate based on an available bandwidth and a number of transmitter devices associated with the one or more SWQEs, and transmit a rate control notification (RCN) message to a transmitter device associated with a send work queue entity of the one or more SWQEs, wherein the rate control notification message comprises the determined transmission rate.

Abstract: Systems, apparatuses and methods provide technology that identifies a message that is to be transmitted across a network, divides the message into a plurality of portions that are arranged in a first order, and generates a plurality of packets based on the plurality of portions. The technology maps different network paths for the plurality of packets to be transmitted to a destination, sets headers of the plurality of packets to represent the first order and the different network paths, transmits the plurality of packets over the network in an out-of-order fashion to the destination based on the headers, and arranges the plurality of transmitted packets into the first order based on the headers of the plurality of packets.
