The above two articles introduce two typical and simple parallel methods, and briefly introduce their performance and advantages and disadvantages. Here we will introduce another method:Micro-ThreadTo synchronize multiple parallel tasks.
Let's imagine the problem below the limit: To search for an element in a known-length huge linear table (such as a one-dimensional array), and all the elements in the table are unique. The processor we use now has two
1. Use the keyboard shortcut "Win+r" to bring up the running dialog box, enter "msconfig" and click OK button. As shown in the following illustration:
2, in the Pop-up System Configuration dialog box, click the "Boot" tab, and then click "Advanced Options." As shown in the following illustration:
3, check "processor number", and select "1" In the Pull-down menu, then click "OK" button. As shown in the following illustration:

Recently, the hype over dual-core processors has been so widespread that the understanding of the technology seems to be out of the truth. Both AMD and Intel are praising the merits of their dual-core processors through their websites. Such campaigns are timely, as most industry watchers believe the dual-core processors will be in the pipeline in 2006.
But behin
improve performance and maintain the stability of the IT environment to upgrade to dual cores without disruption to the business. In a highly rack-dense environment, the customer's system performance will be greatly enhanced by porting to the dual core with the same power and infrastructure investment. In the same system footprint, customers will gain a higher level of computing power and performance through the use of dual
. Test with the following example:intGloopcount;void*task1 (void*Arg) {inti;printf ("starting task1n"); for(i=gloopcount;i>0; i--) {dekker1 ();}}void*task2 (void*Arg) {inti;printf ("starting task2n"); for(i=gloopcount;i>0; i--) {dekker2 ();}}In a single-core processor, the code executes in a multithreaded manner, no matter how many times it is run, the program will not be faulted. Because the memory model o
At present, embedded multi-core processor has been widely used in the field of embedded devices, but embedded human system software development technology still stay in the traditional single-core mode, and do not give full play to the performance of multi-core processor. Pr
Method One, turn off the core frequency function in the BIOS.
Into the BIOS, the cursor moved to the advanced advanced settings inside, advanced Frequency/voltage control, and then to the power technology, find the line with the red lines open, select Enabled Press F10 save can.
Method Two, use power management shutdown.
We can adjust the Power management mode to "High-performance mode", and the p

Single-core processor
Computer system diagram:
The previous chipset consists of two chips, called nanqiao and beiqiao, which are connected through PCI. Later, Intel replaced beiqiao with MCH (memory controller hub) and ICH (I/O controller hub) with nanqiao. The two were connected using DMI (direct media interface. In addition, the master processor is connected t
Recently, many projects have been paying more and more attention to the dual-core technology. although the early dual-core technology was proposed by some server manufacturers, such as IBM and HP, with the universality of technology, dual-core technology is no longer available for high-end devices, for example, dual-core

2. Problem Solving:
After introducing the concepts of "slot" and "lpar", how can we check the number of slots or lpar of the current machine?
First of all, we need to know that lpar has many applications on Minicomputers, and is rarely used on x86 servers. To view the number of slots, run the following command:
[Root @ compute-30-02 ~] # Lscpu | grep "CPU socket"
CPU socket (s): 2
Command to return the result. The number of slots on t
Q: Often in newspapers and magazines to see the word dual core processor, what is the dual core meaning? What's the benefit?
A: In simple terms, a dual-core processor is the integration of two CPUs on a single wafer. So what is a dual-c
Intel Core i5 and i7 can be said to be the most mainstream desktop processor in the market, with a large number of laptops and desktops using these two processors. So, if you want to buy a computer, should consider i5 or i7? Look at the major differences between them.
Hyper-Threading
Hyper-threading means that each processor
Multicore processors are also known as on-chip multi-core processors (chip multi-processor,cmp). 1. Popularity of multi-core processorsBefore Multicore appeared, commercial processors were dedicated to the development of single-core processors, and their performance has been extreme, only increasing the speed of single
With the development of science and technology, dual-core processor is very common in our life, dual-core processor (Dual core Processor) refers to the integration of two computing cores on one

Dual-core CPU processor to a certain extent is to speed up the speed of the computer, but the system is not as intelligent as we think, can reasonably assign the work to each core, the following author to tell us how to set up to play the true dual-core performance.
Step 1th: Add a program to be managed
Select "Add a
For PC enthusiasts, the most want to see the computer is more and more powerful, a generation of CPUs can be improved with the passage of time.
As is known to all, Intel is the world's largest manufacturer of semiconductor chips, and if the core i7-3970x Sandy BRIDGE-E processor It manufactures is compared with the upcoming Intel Ivy Bridge-e processor performan
Researchers at the University of California, Davis (University of California, Davis) recently developed a 1000-core processor called "Kilocore", the world's first processor with 1000 cores. Furthermore, these 1000 cores can also be run independently.The Kilocore can execute 1.78 trillion instructions per second, at least in the
