Abstract: There is disclosed in one example a computing apparatus, including: a hardware platform configured to communicatively couple with a multi-tenant cloud service, the multi-tenant cloud service including an oversubscribable resource; and a service assurance for oversubscribable resource (SAOR) engine configured to: receive tenant subscriptions to the oversubscribable resource, wherein tenant subscriptions exceed available instances of the oversubscribable resource; receive per-tenant quality of service (QoS) metrics for the oversubscribable resource; receive an allocation request from a guest for allocation of an instance of the oversubscribable resource; compare the request to currently-available instances of the oversubscribable resource; determine that the oversubscribable resource has capacity to service the request according to the QoS metrics of the tenant; and allocate an instance of the oversubscribable resource to the guest.

Abstract: A network interface device (NID) interfaced with a host machine communicates with a local link of the host machine to obtain transaction-specific data relied upon by the host machine to be delivered to a destination by the NID according to a reliable message delivery protocol. The NID conducts communications over a network in response to obtaining of the transaction-specific data, with the network communications including execution of the reliable message delivery protocol independent of any operability of the host machine.

Abstract: Described herein are systems and methods using lock-less multi-core IP forwarding having dedicated forwarding cores. The exemplary embodiments may offer wire-rate on multiple gigabit links while guaranteeing packet order. One embodiment relates to a system including a plurality of forwarding cores within a network, and a routing table, wherein a first forwarding core of the plurality of forwarding cores polls data received from an input interface for routing information, references the routing table based on the routing information, determines a destination for the data based on the routing table, and transmits the data to the destination at a wire-rate, the wire-rate is independent from a further wire-rate corresponding to a further forwarding core of the plurality of forwarding cores.

Abstract: A computer readable storage medium storing a set of instructions executable by a processor. The set of instructions is operable to receive an instruction to reserve a processor of a system including a plurality of processors, receive an instruction to perform a task, determine whether the task has affinity for the reserved processor, execute the task using the reserved processor if the task has affinity for the reserved processor, execute the task using one of the processors other than the reserved processor if the task does not have affinity for the reserved processor.

Abstract: A method of managing communication between a plurality of components of a computer system comprises the steps of registering at least a portion of the plurality of components with an intermediary module, wherein the intermediary module is coupled to each of the components and providing from a first one of the plurality of components to the intermediary module a request for a data object. The requested data object is then correlated with a second registered one of the components containing the requested data object and the request is forwarded to the second component and fulfilled by providing the requested data object to the first component.
