Last year in the investigation of a lot of java applications, see some of the phenomenon is the programmer to run on their own environment to read the program rarely lead to troubleshooting problems will be more frustrating, so think of writing this series of articles, procedures To provide functionality to end-users, the code is only one part of it, and it needs to be relied on for jvm, os, server hardware, networking, load balancing, etc. In this series of articles, Several parts, more is only a science role, because os I use are linux, this series ...
At the same time support scheduling memory and CPU resources (default only supports memory, if you want to further scheduling the CPU, you need to make some configuration), this article describes how Hadoop YARN scheduling and isolation of these resources. In YARN, resource management is done jointly by the ResourceManager and the NodeManager, where the scheduler in the ResourceManager is responsible for allocating resources and NodeManager is responsible for providing and isolating resources.

About the hardware and software who is leading this topic, apply a proverb is 30 years Hedong 30 years of Hexi, the wind turbine flow. Software and hardware must be mutually reinforcing, mutually reinforcing and mutually reinforcing. Some of the top-tier structures that were previously criticized may be found to be the most appropriate option in a few years ' time, and will become inappropriate in a few years. Software definition or hardware definition, the same is true, the result of the hardware definition is strong but not flexible, the software definition will begin to brew a comeback, but everything has inertia, software "excessive" definition, will find a lot of things can not be ...
Godson to develop, contracted MIPS is sooner or later, the first two years of godson around to the St. to obtain MIPS authorization, if godson really want to develop, alone contracted MIPS is the only way. Many experts like to link the cause with the national strategy, because the only way to get more project funding from the government, but also to create more Chinese integrated circuits ...
Summer heat, CPU temperature rose, Desktop is OK, notebook on the trouble. It's unsettling. But I've found a solution. Not using the heatsink bracket, is http://www.aliyun.com/zixun/aggregation/7432.html from the source "> Solve the problem."

Xen Virtual CPU idle scheduling algorithm Wang Hou Zi peak in Xen virtualization environment, the credit scheduling algorithm is a preemptive scheduling algorithm, when the virtual CPU is empty, it will not notify the idle state information to Xen, Therefore, the right to use the physical CPU will not be discarded. Although the existing literature has proposed the processing method when the virtual CPU is idle, it still has many problems, such as idle virtual CPU idle time also exists The waste phenomenon, does not consider the privilege service OS idle state and the virtual machine idle state judgment is inaccurate, This causes ...
"Tenkine Office channel November 19 News" The glorious era of the Intel 32 nanometer process processor has led many people to daydream about the application of the CPU in the big Data age, Huang, 32 nm first Daicouri processor and second-generation core processor to introduce core graphics and hyper-Threading technology, Core-frequency technology and so on for Intel in the CPU manufacturing industry has laid a solid foundation. At present, a few 22 nm processors in the market want to make a breakthrough in the process architecture, who will be the market leader in the next era? "Xeon" or "Core I Series"? First, the author ...
Open the computer chassis to see if there are any extra memory slots on the motherboard, and if there are more memory slots, we can buy a new memory bar to add to it. The purchase of memory strips also have a certain stress: it is best to buy and our current memory of the same brand of the same size of memory, so that the compatibility between them better, the overall operating speed will reach 1+1=2 effect, if not the same brand of memory, the general situation is difficult to achieve 1+1=2 effect. When there is no extra memory slot on our computer, or we don't want to spend the amount of money, we can view our ...

This article will explain why thread based programming is not the best way to implement application parallelism in a multi-core era. Moore's Law (Moore 1965 predicts that the number of components per integrated circuit doubles every 18-24 months) is still applicable, and its applicability is expected to continue into 2015-2020 years. Before 2005, the CPU clock rate also increased synchronously, which was enough to improve the performance of all applications executing on those CPUs. Http://www.aliyun.co ...
