Processors 2 ) Amerda's LawIn parallel processing, there is an amerda Law, which is expressed by the equation as follows: S (p) = p/(1 + (p-1) * f) Where S (p) the acceleration coefficient p indicates the number of processors. f indicates the proportion of the serial part in the execution time of the entire program. When f = 5%, p = 20, S (p) = 10.256 when f = 5%, p = 100, S (p) = 16.8 or so that as long a

There are six entries in the/proc/cpuinfo description for multi-core and super-thread (HT) technical checks: processor, vendor id, physical id, siblings, core id and cpu cores. (1) processor: including the unique identifier of the logical processor. (2) physical id: including the unique identifier of each physical encapsulation. (3) core id: the unique identifier of each core.

Article Title: surpassing a single CUP: hyper-threading accelerates Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 　　 Introduction Intel's hyper-threading technology allows a physical processor to contain two logical processors by replicating, partitioning, and sharing resources in the Intel NetBurst microa

workstations with CPU L2 cache up to 256-1MB, some up to 2MB or 3MB. L3 Cache (Level three buffer), divided into two, the early is external, now are built-in. In fact, the application of the L3 cache can further reduce the memory latency and improve the performance of the processor while calculating the large amount of data. Reducing memory latency and increasing the ability to compute large amounts of data can be very helpful to the game. Increasing the L3 cache in the server domain still has

(assuming a value of 1) in its own local memory a. When thread A and thread B need to communicate, thread a first flushes its local in-memory modified x value to main memory, when the X value in main memory becomes 1. Then, thread B goes to main memory to read the x value of the updated thread A, at which point the X value of the local memory of thread B also becomes 1.Overall, these two steps are essentially thread a sending a message to thread B, and the communication process must go through

through main memory. JMM provides a memory visibility guarantee for Java programmers by controlling the interaction between main memory and the local memory of each thread.Re-orderIn order to improve performance when executing programs, the compiler and processor often reorder instructions. There are three types of reordering: The re-ordering of compiler optimizations. The compiler can reschedule the execution of a statement without changing the semantics of the single-threaded procedu

pipeline that shares the execution engine with the first level of the pipeline. The designer wants a second thread or task-related instruction to be queued in a single pipe, and then run the instructions by executing the core when the first instruction pipe is idle. Intel has developed hyper-Threading technology, which enhances multithreading parallel processing on computer systems. The second-level instruction pipeline is included in the processor core, and the operating system recognizes two

the execution thread to be unable to guarantee when the lock will be taken, and some threads may have to wait a long time. With the increasing number of computer processors, this "unfairness" problem will become increasingly serious. The queued spin lock (FIFO Ticket spinlock) is a new kind of spin lock introduced in Linux kernel version 2.6.25, which solves the problem of "unfairness" of traditional spin lock by saving the order information of execu

Until January 10, 09, Microsoft released a beta version of Windows Server 2008 R2 on its website, offering users a 30-day free download trial. Beta version includes Standard Edition, Enterprise Edition, data Center Edition, web version, itanium® version five, the test edition only provides the English language. Although the Windows Server 2008 R2 is not intrinsically different from win 2008, the basic features are of course the same,

In the field of processor chip manufacturing, Intel is a well-deserved industry giant and almost monopolized PC processors. The Wintel alliance with Microsoft even dominated people's PC consumption habits. Mobile chip vendor ARM has begun to enter the server market in an attempt to break Intel's monopoly on the market. Although ARM processors have a 90% market share of mobile phone
