intel core m vs core i5

Unix Today participated in the IBM UNIX World Annual speech meeting, heard the ERP industry some famous manufacturers (SAP, gold disc, Ufida) speech, quite some regrets. See a lot of differences, too. A product, whether it is clothing or software, should emphasize a core competitiveness. So what can be called the core competitiveness? I think the most important thing that users need to achieve in this kind

At present, the computer's CPU is generally multi-core, and many programs have not been optimized for multiple cores, so there is no way to make full use of the CPU performance. For example, if a while (1) loop is written in vs2010, 100% of the CPU runs on the old computer, and 25% of the CPU runs on the new 4-core computer, it seems that it cannot be higher. In many cases, OpenMP can be used to provide mul

　 In a multi-core system, multiple CPU cores compete for the same resource. Therefore, there must be some mechanisms to ensure that there will be no errors in the competition, that is, the synchronization mutex mechanism. This section mainly analyzes and records the spin locks of one of the synchronization mutex primitives. As the interruption part of a multi-core system, it is clear that there will be many

It is very important to improve the throughput performance of multi-core servers. Because servers are different from desktops and workstations, the channel for dealing with the outside world is the network. No matter what complicated computing operations the processor performs, the results must be returned to the request object through the NIC. In a sense, the NIC is the "throat" component of the server for external contact and communication. To some

device to work within 5 degrees of collapse, rather than within 20 degrees, which is both economical and secure. In addition, it is rumored that Intel provides Google with a custom chip for high-temperature design, but James Hamilton, a top expert in the cloud computing field, thinks it is unlikely because although the processor is also very afraid of heat, however, it is much stronger than memory and hard disk, so the processor is not a

In the multi-core era, x86 rdtsc commands should not be used to test the command cycle and time Chen ShuoBlog.csdn.net/solstice Since Intel Pentium added the rdtsc command, this command is a powerful tool for micro-Benchmarking. It can get high-precision time stamp counter at a very small cost ), many articles about optimization [1] and books use it to compare the speed of two sections of code. Some code

year's high-end gamers favored the processor is i7-6700, this processor is currently next to i7-6700k high-end CPU, but does not support overclocking, its built-in core graphics performance is also good. Intel Core i7-6700 is based on the latest Skylake architecture processor, 14nm process, with the latest LGA1151 interface, only supports the 100

1, in-depth Linux kernel premiseBecause I have learned the x86 assembly language of Intel before, so this article does not tell the basic grammar of the Assembly;Kernel Most of the code is implemented in C and assembly language, to understand the kernel, C language Most people have mastered, the next step is to master the assembly knowledge, in order to understand the Linux kernel knowledge!!!2, learn the Linux kernel lineFirst, the kernel has a basic

System invocationSystem calls:This is a way for the user-state process to proactively switch to the kernel state, and the user-State process is requested to complete the work using the service provided by the operating system through system calls. The core of the system call mechanism is to use an interrupt that the operating system is particularly open to the user.Meaning of the system call: Freeing users from the underlying hardware progra

Two years ago, Microsoft's Asian Research Institute published the book "The beauty of programming". Chapter 1 section Section 1 "let you know the CPU usage curve, it can be said that it has set off a game-to-CPU usage curve nationwide. I am even thinking about how to handle the CPU usage curve while taking the bus. The book provides such a refreshing figure, attracting thousands of IT teenagers: You may think this is not fun enough. Me too. By the way, we plan to discuss with you the effect of

, mainly through periodic interrupts. This method has little overhead and high precision. In Linux systems, Oprofile and the Intel VTune Performance Analyzer are more common. Ø Inserting pile type analysis tool That is, you can use a direct binary insert, or you can insert analysis code into your application by using the compiler. This approach is similar to adding a timer function to your application, and it brings a lot of overhead, but provides mo

Deep Java core Java memory allocation principle explainingIntroduction: Stack, heap, Chang, although the same is the Java memory allocation operation area, but its scope of application and function is very different. This article will delve into the Java core and explain in detail the knowledge of Java memory allocation.Java memory allocation and management is one of the

Unix/Linux systems knows that fork's work is actually done by calling the system. The specific work is implemented by sys_fork. In fact, whether it is Unix or Linux, for any operating system, creating a new process is a core function, because it requires a lot of bottom-layer meticulous work, consuming the physical resources of the system, for example, allocating physical memory, copying related information from the parent process, copying the page D
