摘要： An apparatus comprises a plurality of cores and a controller coupled to the cores. The controller is to lower an operating point of a first core if a first number based on processor clock cycles per instruction (CPI) associated with a second core is higher than a first threshold. The controller is operable to increase the operating point of the first core if the first number is lower than a second threshold.

摘要： Embodiments of an apparatus for controlling cache occupancy rates are presented. In one embodiment, an apparatus comprises a controller and monitor logic. The monitor logic determines a monitored occupancy rate associated with a first program class. The first controller regulates a first allocation probability corresponding to the first program class, based at least on the difference between a requested occupancy rate and the first monitored occupancy rate.

摘要： In general, in one aspect, the disclosures describes a method that includes receiving multiple ingress Internet Protocol packets, each of the multiple ingress Internet Protocol packets having an Internet Protocol header and a Transmission Control Protocol segment having a Transmission Control Protocol header and a Transmission Control Protocol payload, where the multiple packets belonging to a same Transmission Control Protocol/Internet Protocol flow. The method also includes preparing an Internet Protocol packet having a single Internet Protocol header and a single Transmission Control Protocol segment having a single Transmission Control Protocol header and a single payload formed by a combination of the Transmission Control Protocol segment payloads of the multiple Internet Protocol packets. The method further includes generating a signal that causes receive processing of the Internet Protocol packet.

摘要： A method and apparatus for is herein described providing priority aware and consumption guided dynamic probabilistic allocation for a cache memory. Utilization of a sample size of a cache memory is measured for each priority level of a computer system. Allocation probabilities for each priority level are updated based on the measured consumption/utilization, i.e. allocation is reduced for priority levels consuming too much of the cache and allocation is increased for priority levels consuming too little of the cache. In response to an allocation request, it is assigned a priority level. An allocation probability associated with the priority level is compared with a randomly generated number. If the number is less than the allocation probability, then a fill to the cache is performed normally. In contrast, a spatially or temporally limited fill is performed if the random number is greater than the allocation probability.
