Hadoop yarn also supports two resource scheduling for both memory and CPU, and in yarn, resource management is performed by ResourceManager and NodeManager, where the scheduler in ResourceManager is responsible for allocating resources, and NodeManager is responsible for the supply and isolation of resources. 　　This article Dong Xi will introduce some of the progress of yarn in resource isolation. Author of the original: resource scheduling and resource isolation is yarn as a resource management system, the most important and most ...

I. Introduction We often see some similar in the program disassembled code 0 × 32118965 this address, the operating system called linear address, or virtual address. What is the use of virtual address? Virtual address is how to translate into physical memory address? This chapter will give a brief account of this. 1.1 Linux Memory Addressing Overview Modern operating systems are in 32-bit protected mode. Each process can generally address 4G of physical space. But our physical memory is generally hundreds of M, the process can get 4 ...

Adb bugreport records the log of the android startup process, as well as the system state after startup, including the process list, memory information, VM information, etc.

Preface & http: //www.aliyun.com/zixun/aggregation/37954.html "> As the project, you need to count the computer resources used by each business group, such as cpu, memory, io read and write, network traffic. Need to read the source code to see Hadoop's default counter. MapReduce Counter can be ...

Everyone wants the computer to start immediately into the Windows system without waiting, or the system in the use of the time will not be more and more slow, but for a variety of reasons often make these wishes can not be achieved, or even a startup on the crash or use the situation is more and more slow to occur often. In fact, sometimes Windows start slow is not its own problem, but some equipment or software. This article is the software, hardware and virus three major aspects to analyze the system slows down the reason, and provides a system-specific acceleration techniques. ...

The cloud infrastructure, such as Amazon EC2, has proven its value worldwide, and its ease of scaling, out-of-the-way, on-time billing, and so on, has freed developer creativity more thoroughly, but don't overlook the virtualized environment that was once considered a performance killer for applications and databases. Despite the performance aspect, cloud vendors have been looking for ways to improve, but as users of us, our own performance optimization tools are also essential. On the entity server, Aerospike has shown the peak of the million TPS, and now we are dedicated to improving the performance of cloud applications ...

The emergence of GPU in recent years, the development of high-performance computing can be described as playing an immeasurable role in promoting. GPU computing on the order of magnitude increase in performance so that it has more success than traditional solutions success stories. A large number of technology workers love, sought after or use GPU technology, but at the same time there are more people for a variety of reasons to sit idly by. This article addresses the latter and summarizes some of the most common problems, concerns, or subjective assumptions in the field of GPU computing. The rest of this article will attempt to address these challenges by rethinking these questions as GPU computing progresses and our projections of future technological developments ...

Recently read some Linux command line articles, in the system information to learn a lot of commands. Think of a previously written article in fact, Linux so much easier to find these system information to view the command can also be summed up a small thing to come. # CAT/PROC/MTRR View Mtrrs Memory type range Registers # uhttp://www.aliyun.com/zixun/aggregation/11696.html >name-r view current kernel ...

At the beginning of July, the seven-Hi computer, which was getting closer to AMD, was abruptly downgraded by Intel – downgrading seven-Hi Localoem partners to channeloem customers. A complaint about Intel mode followed, seven-Hi holding Company (002027.　　SZ) Vice president of the Mao Jun, said the first financial daily, including the "Market fund rebate" policy, such as the establishment of Intel's business unspoken rules, has made the Chinese PC industry to drink "chronic poison", not only on the market risk resistance is worse, but also unable to extricate themselves. Whether forced or active to eat ...

The private cloud is another widely used application of cloud computing since the public cloud. Private cloud performance monitoring plays an important role in not only diagnosing failures, but also making a contribution to ensuring that service levels meet the needs of centralized services. To ensure success, smart IT staff often create efficient virtualization strategies to perform performance monitoring for private clouds. Continuous collection of private cloud performance monitoring data The private cloud is about processes, automation, people management, and consolidation. Some private clouds use virtualization technology and physical host hosts, so no matter what kind of tool you use ...
