frequently used pages from being flushed out of the TLB cache This flag is enabled only if the page global enable (PGE) flag is set on the CR4 register Extended Paging Page Catalog item's page size flag enables extended paging feature Extended paging allows page box size to be 4MB instead of 4KB Extended paging is used to convert a contiguous linear address of a large segment to a physical address

Excel files, the basic method is to use component multiplexing technology to invoke the COM service components provided by the Office software platform, taking advantage of the methods provided by COM components to manipulate Excel files. The application example in this article is a simple demonstration of how COM technology can be used to output data from a dataset dataset to an Excel file. The implementation process and the main source code are as follows: Create a new window class Tfrmcomexc

: The GNU Compiler Collection (GCC) C editor on a 32-bit PowerPC platform (such as Apple PowerBook running Linux) can generate a 32-bit platform on the local machine, or a 32-bit binary file executed on a 64-bit Linux on power platform that contains an appropriate 32-bit user space library. Ibm xl c/C ++, version 8.0, and the gcc C compiler for 64-bit Linux on power can generate 32-bit and 64-bit binary executable files, these files can be

Switch stack Technology 1. catlyst 1900 ------- most of them use chrysanthemum chains (I think there is no difference with cascade), but cisco thinks they are stacks: (www.2cto.com chrysanthemum chains: as the name implies, A vswitch is connected in a string (using a crossover line ). In this case, the first server must communicate with the fourth server, and must pass through two or three servers. We can imagine that data needs to be forwarded multiple times during transmission. The communicati

This article describes the important Java Native Interface (JNI) programming concepts through some simplified examples, and points out that it is specific to POWER™On Linux™And common programming risks. Introduction Programming those new to the Java Local interface and wanting to release the Linux version for POWER (such as Red Hat Enterprise

, hvm is semi-virtualized. Semi-virtualization can only run the modified kernel, but can achieve higher performance. Allocate two CPUs and 2 GB memory for the virtual machine, and specify the hard disk image file. The last sdl = 1 indicates that the virtual operating system interface is displayed using the SDL graphics library. If you do not want to use SDL, you can also write it as vnc = 1. In this way, you need to use vncviewer to connect to the desktop of the virtual machine operating system.

A. About stacking technology: How does the 1.Catalyst 3500XL/2900XL stack be implemented? A. Special tiered cabling is required, 1 m long or 50 cm long (cab-gs-1m or cab-gs-50cm) and a dedicated gigabit stacked card Gigastack GBIC (WS-X3500-XL) (which already contains cab-gs-50cm stacked cables). B. There are 2 stacking methods available: Daisy Chain (providing 1G of bandwidth) or point-to-point method (2G bandwidth available). C. 2 ways to do back

transfer command from MRC coprocessor register to arm register Usage: CDP P5, 2, C12, C10, C3, 4; coprocessor P5 operation initialization, where the operation code 1 is 2, the operation code 2 is 4, and the target register is C12, source operand register bits C10, and C3 LDC commands read data from a series of consecutive memory units to the coprocessor register. If the coprocessor fails to perform this operation, undefined command exception operations will be generated. Example: LDC P6,

This table stores EPT paging struc-tures (GPA --> hPa ). 2: EPT is stored in the guest address space and can be operated under VM non-root without VM exit. 3: At this time, Guest OS has two page tables, one common () and the other (EPT.

dual-Gigabit Ethernet provides the customer with great deployment activity-allows the customer to implement a current stack and uplink configuration, at the same time, it reserves space for future configuration migration. In the future, customers who want to deploy converged network applications must consider deploying LAN devices, such as switches that can support these increasing demands. Such switches should be able to process time-sensitive information, such as voice and key data informatio

Xen 4.2 will contain two new scheduling parameters for the credit1 scheduler which significantly increase its confurability and performance for cloud-based workloads:Timeslice_msAndRatelimit_us. This blog post describes what they do, and how to configure them for best performance. Timeslice The timeslice for the credit1 has historically been fixed at 30 ms. this is actually a fairly long time-it's great for computationally-intensive workloads, but not so good for latency-sensitive workloads,
