    Abstract: A computer system includes one or more processors, one or more hardware accelerators, and control circuitry. The processors are configured to run software that executes tasks in a normal mode. The accelerators are configured to execute the tasks in an accelerated mode. The control circuitry is configured to receive one or more flows of tasks for execution by the processors and the accelerators, assign one or more initial tasks of each flow for execution by the processors, assign subsequent tasks of each flow for execution by the accelerators, and verify, for each flow, that the accelerators do not execute the subsequent tasks of the flow until the processors have fully executed the initial tasks of the flow.

    Abstract: A network interface device includes a host interface for connection to a host processor having a memory. A network interface is configured to transmit and receive data packets over a data network, which supports multiple tenant networks overlaid on the data network. Processing circuitry is configured to receive, via the host interface, a work item submitted by a virtual machine running on the host processor, and to identify, responsively to the work item, a tenant network over which the virtual machine is authorized to communicate, wherein the work item specifies a message to be sent to a tenant destination address. The processing circuitry generates, in response to the work item, a data packet containing an encapsulation header that is associated with the tenant network, and to transmit the data packet over the data network to at least one data network address corresponding to the specified tenant destination address.

    Abstract: A method includes receiving a dividend and a divisor for performing a division operation. Numbers p and n are found, for which the divisor equals 2n(1+2p). An interim result, which is equal to a reciprocal of 1+2p multiplied by the dividend, is calculated. The interim result is divided by 2n to produce a result of the division operation.
