摘要： In accordance with some embodiments, a cloud service provider may operate a data center in a way that dynamically reallocates resources across nodes within the data center based on both utilization and service level agreements. In other words, the allocation of resources may be adjusted dynamically based on current conditions. The current conditions in the data center may be a function of the nature of all the current workloads. Instead of simply managing the workloads in a way to increase overall execution efficiency, the data center instead may manage the workload to achieve quality of service requirements for particular workloads according to service level agreements.

摘要： Systems described herein operate to improve network performance in a multi-tenant cloud computing environment. Systems can include communication circuitry and processing circuitry to generate a phase sequence matrix that indicates the identity and number of phases of a workload by measuring resources of the compute node during execution of the workload throughout a lifetime of the workload. The processing circuitry can generate a workload fingerprint that includes the phase sequence matrix and a phrase residency matrix. The phase residency matrix can indicate the fraction of execution time of the workload spent in each phase identified in the phase sequence matrix. A cloud controller can access the workload fingerprint for multiple workloads operating on multiple compute nodes in the cloud cluster to adjust workload allocations based at least on these workload fingerprints and on whether service level objectives (SLOs) are being met.

摘要： Technologies for deploying dynamic underlay networks in a cloud computing infrastructure include a network controller of the cloud computing infrastructure communicatively coupled via disaggregated switches to one or more compute nodes of the cloud computing infrastructure. The network controller is configured to receive tenant network creation requests from a cloud operating system (OS) of the cloud computing infrastructure indicating that a tenant network is to be created in the cloud computing infrastructure (e.g., for a new tenant of the cloud computing infrastructure). The network controller is configured to provision an underlay network to support the tenant network based on identified physical resources using criteria specified by the cloud OS and transmit information of the provisioned underlay network to the cloud OS that is usable to create a cloud visible overlay network associated with the underlay network. Other embodiments are described herein.

摘要： A coordinated mechanism to conserve power in a multi-node environment is disclosed. A multi-node environment may comprise multiple individual computer systems coupled by a network or, a shared memory architecture multiprocessors, or many-core computers. The power management features of the processor, platform elements, and the devices may be used to conserve power in a multi-node environment. A master node may determine the task and slave nodes required to perform the task and may wake-up the slave nodes required to perform the task while causing the other slave nodes to enter or continue in the sleep-state. The slave nodes, which are woken in-turn may determine the components of the slave nodes required for performing the assigned task and may cause other components to enter a sleep-state.
