Abstract: A system includes a device configured to execute workloads coupled to a processing device. The processing device is to receive a request to execute one or more workloads, the request comprising two or more numbers corresponding to a rational value associated with a rate to execute the one or more workloads. The processing device is further to determine the rate to execute the one or more workloads responsive to receiving the two or more numbers corresponding to the rational values. The processing device is to execute the one or more workloads at the determined rate.

Abstract: A method including configuring a transmit process to store information including a queue of packets to be transmitted, the queue defining transmit process packets to be transmitted, each packet associated with a transmission time, and configuring a synchronization process to receive from the transmit process at least some of the information. The synchronization process performs one of: A) accessing a dummy send queue and a completion queue, and transmitting one or more of the transmit process packets in accordance with a completion queue entry in the completion queue, and B) sends a doorbell to transmission hardware at a time when at least one of the transmit process packets is to be transmitted, the synchronization process including a master queue configured to store transmission entries, each transmission entry including a transmit process indicator and an indication of transmit process packets to be transmitted. Related apparatus and methods are also described.
