In various embodiments, an apparatus for computing may receive a datacenter performance target, determine an end-to-end datacenter performance level based at least in part on quality of service data collected from a plurality of nodes, and send a mitigation command based at least in part on a result of a comparison of the end-to-end datacenter performance level determined to the datacenter performance target. In various embodiments, the apparatus for computing may include one or more processors, a memory, a datacenter performance monitor to receive a datacenter performance target corresponding to a service level agreement, and a mitigation module to send a mitigation command based at least in part on a result of a comparison of an end-to-end datacenter performance level to a datacenter performance target.

Abstract: Methods and apparatus for efficient peer-to-peer communication support in interconnect fabrics. Network interfaces associated with agents are implemented to facilitate peer-to-peer transactions between agents in a manner that ensures data accesses correspond to the most recent update for each agent. This is implemented, in part, via use of non-posted “dummy writes” that are sent from an agent when the destination between write transactions originating from the agent changes. The dummy writes ensure that data corresponding to previous writes reach their destination prior to subsequent write and read transactions, thus ordering the peer-to-peer transactions without requiring the use of a centralized transaction ordering entity.

Abstract: Examples may include techniques to coordinate the sharing of resources among virtual elements, including service chains, supported by a shared pool of configurable computing resources based on relative priority among the virtual element and service chains. Information including indications of the performance of the service chains and also the relative priority of the service chains may be received. The resource allocation of portions of the shared pool of configurable computing resources supporting the service chains can be adjusted based on the received performance and priority information.

Abstract: In one embodiment, a processor includes a first cache and a second cache, a first core associated with the first cache and a second core associated with the second cache. The caches are of asymmetric sizes, and a scheduler can intelligently schedule threads to the cores based at least in part on awareness of this asymmetry and resulting cache performance information obtained during a training phase of at least one of the threads.

Abstract translation: 在一个实施例中，处理器包括第一高速缓存和第二高速缓存，与第一高速缓存相关联的第一核和与第二高速缓存相关联的第二核。 高速缓存具有非对称尺寸，并且调度器可以至少部分地基于对至少一个线程的训练阶段期间获得的不对称性和结果高速缓存性能信息的认识来智能地将线程调度到核心。
