Abstract
A network interface card (NIC) receives a stream of commands, a respective command comprising memory-operation requests, each request associated with a destination NIC. The NIC buffers asynchronously the requests into queues based on the destination NIC, each queue specific to a corresponding destination NIC. When first queue requests reach a threshold, the NIC aggregates the first queue requests into a first packet and sends the first packet to the destination NIC. The NIC receives a plurality of packets, a second packet comprising memory-operation requests, each request associated with a same destination NIC and a destination core. The NIC buffers asynchronously the requests of the second packet into queues based on the destination core, each queue specific to a corresponding destination core. When second queue requests reach the threshold, the NIC aggregates the second queue requests into a third packet and sends the third packet to the destination core.
