BACKGROUND Many processors include a time stamp count (TSC) counter which is typically implemented as a counter that increments at a fixed rate. Some known TSC counters are clocked at a bus clock rate and a multiplier value is added each bus clock cy…

CPU Basics: Multiple CPUs, Cores, and Hyper-Threading Explained 现在多数的家用电脑,仍然使用的是 Single CPU,Multiple Cores(单颗 CPU,多个核心),而多 CPU 系统一般只见于超级计算机. 大型服务器等需要巨大计算能力的系统.之所以不将 PC 设计为多 CPU,在于带来的代价和成本的提升. 多个 CPU,在主板上即需要多个 CPU 卡槽,还需引入 CPU 之间的通信机制,自然地多个 CPU 系统也将损耗更…

As Ed Essey explained in Partitioning in PLINQ, partitioning is an important step in PLINQ execution. Partitioning splits up a single input sequence into multiple sequences that can be processed in parallel. This post further explains chunk partition…

BACKGROUND OF THE INVENTION The present invention relates to a storage system offering large capacitance, high performance, and high availability through a hierarchical construction of RAID and a method for controlling the storage system; and more pa…

BACKGROUND OF THE INVENTION Mobile devices, such as but not limited to personal data appliances, cellular phones, radios, pagers, lap top computers, and the like are required to operate for relatively long periods before being recharged. These mobile…

BACKGROUND OF THE INVENTION With the rise of multi-core, multi-threaded data processing systems, a key performance consideration is the coordination of the processing performed by multiple concurrent threads. In conventional systems, coordination of…

BACKGROUND OF THE INVENTION The present invention relates generally to single-instruction, multiple-data (SIMD) processing and, more specifically, to a technique for saving and restoring thread group operating state. In a conventional SIMD architectu…

BACKGROUND INFORMATION An embodiment of the present invention relates generally to virtualization platforms and, more specifically, to a system and method to run components of a virtual machine monitor at a reduced privilege level. Various mechanisms…

BACKGROUND Embodiments of the invention relate to the field of electronic systems and power management. More particularly, embodiments of the invention relate to a method and apparatus for a zero voltage processor sleep state. As the trend toward adv…

BACKGROUND Advances in semi-conductor processing and logic design have permitted an increase in the amount of logic that may be present on integrated circuit devices. As a result, computer system configurations have evolved from a single or multiple…
