1 socket, core, thread(1) Socket is the number of slots on the motherboard to plug the CPU, that is, the administrator said "road"The chip manufacturer encapsulates one or more cores on a chip, called a socket. Assuming a slot has two cores, the motherboard is plugged into 2 slots, which is the 4-core system.(2) Core is what we usually call "nuclear", that is, dual-core, 4-core and so on. Single-core (Single-core) and multicore (multi-core) are also known as uniprocessor and multiprocessor(3) th
Linux supports a single system with multiple processors. Except for the boot process, the process scheduling program is responsible for a large amount of work that supports multiple processors. In Symmetric Multi-processing (SMP) and above, the process scheduler must determine which processes are running on each CPU. Two challenges arise from this responsibility: the scheduler must make full use of all the processors in the system, because when one process is ready to run, one CPU is idle, this
I will upload my new book "Write a processor by myself" (not published yet). Today is the beginning. I try to write an article every Thursday.
Introduction
In this book, we designed and implemented openmips, a processor compatible with the mips32 instruction set architecture. The openmips processor has two versions: Teaching edition and practical edition. The m
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 behind these phenomena, and in the many related media reports, there are hidden truths that are not known and unusual. Below, we'll tell you

Article Title: Understand the average processor load of 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.
You may have a good understanding of the load averages in Linux. The average load value can be seen in the uptime or top command. They may look like this:
Load average: 0.09, 0.05, 0.01

Why is the actual frequency of only 2500g amd + processor running faster than the actual frequency of 2G P4-2.4B is faster? Why is the tulatin core processor with a 0.13 micron process capable of achieving a maximum of 1.4 GB? Instead, the Willamette core processor with a 0.18 micron process can easily achieve 2 GB? Next, let's analyze why the above two "strange
Assembled computer friends generally must have a certain understanding of computer hardware, must understand its balance, the balance between components and hardware performance, processor is computer enthusiasts are very concerned about, so what kind of processor is a good processor (CPU)? Generally we look at the main proce
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. Program parallelization optimization At present in the PC platform has certain use, but in the embedded platform is very few, in addition

Note that the following English word cache is used. If C is in uppercase, that is, cache, it indicates the term "cache". If C is in lowercase, that is, cache, indicates the verb -- indicates saving data to a high-speed buffer storage.
Intel 64 and the IA-32 architecture provide the ability to manage and enhance the execution of multiple processors connected to the same system bus. These include:
period.APTAnnotation Processing Tool is a built-in Tool for javac to scan and process Annotation information during compilation. From JDK 6, apt exposes available APIs. A specific processor receives a Java source code or compiled bytecode as the input, and then outputs some files (usually. java files ). This means that you can use apt to dynamically generate code logic. Note that apt can only generate new Java classes and cannot modify existing Java

Users need to assemble a computer, the first need to build a set of suitable for their own computer configuration, if the configuration is not suitable for their own affirmation is not, for example, they like to play a large game, and configure the performance of the game is not strong, large games will play up to compare cards, so want to play
Computer configuration is not difficult to build, as long as the computer hardware with each other to ensure compatibility between the hardware, which i
access process cannot be 0. Conversely, if va[31:25] equals 0, the address VA to be accessed is within the process's own address space, so a process context switch is made to convert VA to MVA, where the PID of the above formula is the PID number of the process.

Later carefully think about the wrong, a single extraction seems to be able to do, the dynamic variable number of extraction, but also splicing, it seems to write, even if it can be written to estimate is disgusting death.

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

In layman's terms, Apache NiFi is an easy-to-use, powerful, and reliable data processing and distribution system designed to support data routing, transformation, and system mediation logic for highly configurable indicators.To be clearer about what Nifi can articulate, the following is a brief introduction to the Nifi architecture, as shown in.Acc
