the establishment of MPI parallel computing environment first, the preparation work before the configuration Suppose the cluster is 3 nodes. 1. Install the Linux (CentOS 5.2) system and ensure that the sshd service of each node can start normally. Instead of using the real 3 machines, the author uses a virtual machine (VMware Workstation6.5) to simulate multiple Linux systems on a machine equipped with an XP system. Precautions: (1) because the autho

From http://blog.csdn.net/iefreer/article/details/32715153 Spark is based on the idea that when the data is large, it is more efficient to pass the calculation process to the data than to pass the data to the computational process. Each node stores (or caches) its data set, and then the task is submitted to the node. So this is the process of passing the data. This is very similar to Hadoop map/reduce, in addition to actively using memory to avoid I/O operations, so that the iterative algori

Cloud computing Data and Information Security Protection The processing and storage of cloud computing data are carried out on the cloud platform. The separation of computing resource owners and users has become an inherent feature of the cloud computing model, as a result, users' concerns about secure storage and priv

Controllable cache for improving the performance of computing reports with clear sets, and controllable reports It is an indisputable fact that using cache can improve report performance. Generally, high-end report tools provide the report cache function to cache the computing results of the entire report to the file system, this allows you to quickly read the cache results for report presentation when you

Before we talk about the cloud computing data Center, we need to understand what is cloud computing? Cloud computing refers to the delivery and usage patterns of IT infrastructure, which means acquiring the required resources over the network in an on-demand, extensible manner. A network that provides resources is called a "cloud." "Cloud" Is it resource pool, ca

Recently looking at business model-related books, the brain has a cloud computing model, thinking for a long time, still vague, or to share out their own ideas, but also want to listen to different voices and opinions, feel their own talents, may be some of the following technical problems and misunderstandings, are welcome to criticize the people from all walks of life. Introduction In the era of Internet and globalization, there are two major tech

DespiteComputing) there is still no unified definition, at least 20 cloud computing voices in the enterprise IT industry. Markus KLEMS Cloud computing is a buzzword that includes development, load balancing, business models, and architecture. It is the future model of the software industry (software 10.0). Or simply put, cloud computing is based onInternet-centr

One of the latest buzzwords in the IT industry is cloud computing. Cloud computing refers to distributed computing resources that can choose quantitative computing capabilities. What kind of computing resources is "available" and changes with the circumstances. In fact, most

In this sd2c conference, cloud computing is undoubtedly the most popular technology topic (none ). In contrast, Oracle is the only one in the grid technology. After coming back, he discussed this topic with Ling Hu In the BT Group and Fb dinner, and Ling Hu still had full expectations for grid technology-idea of GRID network. From a technical point of view, cloud computing is indeed regressing in a sense, f

Spatial Economic computing visualization Visualization is a theory, method, and technology that uses computer graphics and image processing technology to convert data into graphs or images displayed on the screen and perform interactive processing. It involves many fields such as computer graphics, image processing, computer vision, and computer-aided design. It has become a comprehensive technology that studies a series of problems such as data re

In actual information systems, a lot of data computing is performed for front-end display. Reports are the most common form. These computing implementation processes are often not simple, and it is difficult to use SQL or stored procedures, thus affecting the front-end report design. For example, a statement (including an inventory coverage period, which facilitates production scheduling or procurement task
