As the international community’s concern about the global environment De surge with the Japanese oil industries is to ensure that no harm to the ecological environment在circumstances, for efficient exploration and exploitation of the energy sector is currently the main topic . Intel High Performance Computing 2010 conference , Intel energy and high throughput computing team • Thierry Philip , senior director of engineering , said , as the global oil resources dwindling , the depth of exploitation of existing fields , the oil industry forced into more Complex environment , more complex computational model needs more computing systems , 10 billion billion calculations are likely to be in the oil industry first.Recently released its 35th Annual Global Top 500 list of high-performance computing , Intel a total of 408 sets of Ranking system , accounting for nearly 82% of the share list , and 90 % of the quad-core systems are using the Intel Xeon processor Devices ( eye-catching is: there are seven sets of the list in the system uses the Intel Xeon 5600 series processors ( code-named : Westmere-EP), there are 2 sets is based on the new Intel Xeon 7500 series deal Device (R & D Code : Nehalem-EX)). Most of the energy used in scientific computing and computing ( such as the U.S. Department of Energy , the oil in the petrochemical, and other ultra- count room ) . Shows that high performance computing at the Intel Multi-core processors high performance computing customers have been fully recognized .Energy and high- throughput computing Intel senior director of team engineer Philip • Mr. Thierry
Mr. Thierry , from the 70′s to the present , the use of geophysical research claerbout migration equation of state , Tarantula inverse problem theory and other theories , combined with modeling, data acquisition for fault analysis . Early analysis is mainly based on 2D data collection , starting from the 90′s began to use 3D data acquisition mode , and the gradual upgrade to 3D WAZ way . Mr. Thierry believes that with the improvements in imaging mode , geophysical gradually from the 2D image ( such as 2D WEM, 2D RTM , etc.) evolve to 3D imaging mode .However , 3D imaging computing for the background too much pressure , 90 in the early oil exploration in general not use too fine a complex algorithm that is because it was a super computer performance is not high, an exploration of available data often requires several months Computing time imaging . Now, Xeon family of processors made progress in supercomputer jump to petascale (Pflops) level , which greatly reduces the computing time for exploration of data – making it possible to construct accurate 3D imaging , which must be used Seismic oil exploration is made .
It is understood that oil exploration seismic wave method using high-performance computing applications , can be divided into seismic data processing and reservoir simulation of two categories. Seismic data processing is a typical floating-point compute-intensive applications to solve data -intensive computing wave equation as the main mode , and therefore require a higher floating-point computing power , a lot of intensive treatment on the need for good multi-core scalability. The reservoir simulation demands on computing platforms is the need to support sparse iterative matrix equation solving , onMemoryVery high bandwidth requirements and the need to support large cache , so such software can be grouped into pairsMemoryBandwidth intensive applications highly sensitive .
Combination of these two categories of oil exploration core characteristics of high-performance computing applications , and oil exploration business enterprise computing tasks for the efficiency and cost requirements for this area of high performance computing solutions , we must have the following four characteristics :
1 . with a strong performance , especially in floating-point computing performance , parallel computing performance andMemorySubsystem properties;
2 . has an excellent performance and cost efficiency ;
3 . with excellent software development and tuning tools;
4 . complies with open standards , hardware and software partners have extensive levels of support .
Now widely used for the oil industry, the commercial client seismic data processing software has a Paradigm of Geodepth and Focus, Western Geco ‘s Omega, CGG ‘s GeoCluster, these applications are to support large-scale parallel computing cluster version . Seismic data processing is a typical floating-point compute-intensive applications to solve data -intensive computing wave equation as the main mode , and therefore require a higher floating-point calculations onMemoryBandwidth occupied by the middle of a large number of guns a good set of multi-core processing needs scalability .On the other hand , domestic self-developed software is mainly used this type of pre-stack time migration PSTM and PSDM depth migration algorithms , such as the East China Petroleum Geophysical Corporation (BGP) independently developed GeoEast, Nanjing, China Petrochemical Oil Geophysical Institute of the development of iCluster so . In calculating the precision and complexity, the major foreign manufacturers and other WesternGeco has begun to reverse time migration and so consumption RTMCPUResources more accuracy and higher production offset algorithm . China’s domestic oil companies such as Eastern Geophysical Company began to try to CRAM a total reflection angle Paradigm shift module .
Mr. Thierry believes that this type of seismic wave method for calculating the exploration , the performance of the intended user is the key factor – that means less computing time. And his point of view , the performance is just to do everything possible toCPUThe most efficient mode of operation to maintain the required load .

Recently circulated an online news, Jinshan announced the launch of the domestic security companies, called “Gold Mountain guard V10″ high-tech plan to formally enter the field of automotive safety. Kingsoft out later clarified that this is fool’s day security firm to open a small joke.
Although he is a fake news, but its content has led to the author for the future development trend of the security market deep thinking.
Prior to this, both the enterprise security market or consumer market, its scope is mainly centered on the comprehensive protection of PC hardware and software, Internet and mobile communications with the rapid development of the security market has extended to mobile terminals in the field, But the original mode of thinking has not been a qualitative change.
This is false news, then I see the future for security applications market is very extensive and attractive prospects. In this paper, such as “Gold Mountain defender V10″ program through the vehicle of graphic information collection devices, V10 chip, cloud computing at the server build a set of car stereo protection system. The chip can automatically collect and process vehicles inside and around the terminal voice, video, lighting and so on, upload to the cloud security server, with its powerful storage and computing power, will upload the information and public security organs to compare the safety database accurately determine whether the theft occurred, and the automatic completion of evidence gathering, it can be smart to recognize and act to prevent auto theft and assist the public security organs quickly caught the thieves.
And this technology has the universal application of the model, also apply to catering, finance, medicine and other fields, can provide a broader application of innovative security technology.
Readers can easily see, the above described case of security applications, the identification of the object is no longer a traditional computer viruses and Trojans, but with a database of existing data and information than you can say it is the deepening of the security market applications, “pan-security” concept. However, carefully think about the original security vendors is that their core competencies such as killing the virus Trojan horse, rather like the case mentioned in the methods of identification, in fact, companies can engage in non-security, this shows that the future of the security market will face redefined.
Also from this case itself, it refers to using the latest, “cloud security” concept, in fact more a “cloud computing” concept; application to 3G wireless technology and sensors, CPU processing chip, etc., characterized by complete meet the definition of scope of the current Internet of Things, Internet of things are typical application cases.
Through the above analysis, I would like to give security vendors tremendous inspiration yes, should be inherent in the tradition of thinking out of Yi Wang, actively track and Changshizuixin development of technology, try to more broader space for development to gaining a competitive advantage.

AP:As the most popular blog platform WordPress, it gives users a variety of tools, users can publish articles using these tools, interaction with readers remain. WordPress today officially released WordPress 3.0 RC3 version, like the early adopters of a friend are you. After RC1 and RC2 versions of the test, RC3 version fixes the final number of bugs, RC3 may last a RC version will be released after the official final version. According to official Note previous Bowen, the official version of the release time will be within this month. Although WordPress3.0 compared with the previous version, changes have not a lot, but it is very meaningful, especially for the hope to WordPress as a content management system used by the user.
Upcoming WordPress3.0 the most prominent features of the five new
1. Custom publishing content types
By default, WordPress allows you to publish in two types of content: “article (Posts)” and “pages (Pages)”. In WordPress3.0 version, you can attribute characteristics based on the definition of the content itself more content types.
2. Menu Management
Menu management should be WordPress3.0 most people relish a new function. It allows you to completely control the site’s navigation menu. Through easy drag and drop interface, users can freely create various combinations of links: internal links, external links, categories, etc.. And you can embed these custom menu theme anywhere, look at them as widgets.
3. Since the definition of classification
For non-developers, this new feature may be a bit complicated, but anyway, it will no doubt WordPress3.0 to a real content management system, a step forward again. Custom classification allows you to create additional meta information. By default, there is a “classification” and “label” the two. Now you can add more types, and can choose whether hierarchical structure.
4. The new default theme: “Twentyten”
Twentyten this subject let us look forward to a long time, this theme is simple but introduced a number of other topics that are not in perfect function. If you are new to WordPress, do not know how to use code to customize the theme, Twentyten built the following two functions will be even more useful:Custom header image, custom background image.
5. Multi-site
That WordPress 3.0 is impossible not to talk about the new multi-site functionality. This is the case, you can simply install a WordPress, you can manage multiple different sites (different domain or sub-domain). Previously known as WordPress MU (multi-user) functionality is now combined in a kernel WordPress3.0. However, not suitable for ordinary users to enable multi-site functionality, because it requires a certain code of knowledge also need to configure the server. That is, ordinary users may not have any interest in multi-site functionality.
Edit reminder: Open To enable 3.0 features multi-site, you only need to open the root directory of WordPress wp-config.php file, anywhere in the file with the following:define (‘WP_ALLOW_MULTISITE’, true);
Download:WordPress 3.0 RC3
Development of reading:
WordPress is a focus on aesthetics, ease of use and network standards, personal publishing platform. WordPress is free open source software, though, WordPress is a free open source project under the GNU General Public License license. But its value can not be measured in monetary terms. Use WordPress to build a strong network of successful information publishing platform, but more is applied to personalized blog. The application for the blog, WordPress allows you to Government tries background technical concerns, to concentrate on the content of the site.
WordPress is a blog developed using the PHP language platform, users can support PHP and MySQL database server, set up their own blog. Can also WordPress as a content management system (CMS) to use.

Internet giant Yahoo Inc. with world-renowned mobile phone manufacturer Nokia has formed a strategic alliance. The two were in the field of traditional Internet and mobile phone companies to achieve impressive results, a move designed to the advantage of both sides, “as Internet users or mobile users with a better user experience,” the loss back to Apple and Google Corporation competitors market share.
If the first 10 years of the 21st century is the era of the Internet, then the next 10 years will be mobile Internet era. As the Internet has profoundly affected the social life, as mobile Internet will become a part of life. Nokia and Yahoo This is probably the real reason for an alliance. With 3G, is the third generation mobile communication technology of rapid development, more and more traditional Internet users started using mobile Internet services, and even some did not to start using the Internet to mobile Internet users. China Mobile Communications Research Institute Bill Huang that a growing number of polymer applications, a variety of media are gradually entering the mobile communication, mobile communication and mobile terminal has become the information society and information services, the core platform.
The emergence of mobile Internet is dramatically changing the lives of people in the information age. Mobile Internet applications with various terminal devices, can carry the characteristics of a wide range of specific applications. Mobile music, mobile games, video applications, mobile payment, location, etc. The application is the rapid development of rich and varied, but most of these applications the requirements for the device type configuration is not very high. In particular, with the growing popularity of smart phones, smart phones increasing the number of user groups, users for mobile applications, in particular the interaction of life growing demand for secondary applications. Apple iPhone, a great success, driven by rapid growth of the smartphone market. A market research firm recently released a report in the first quarter of the total global shipments of smart phones reached 54 million, up 50%. Apple’s success has sent a clear signal to the industry: the mobile Internet market contains a huge gold mine.
Yahoo and Nokia recognizes that, with mobile phone users in emerging economies has become an important Internet tool, to expand services in emerging economies is important. Great potential in emerging market economies, increasing mobile phone penetration. For example, China has more than 700 million mobile phone users, mobile phone close to 200 million Internet users. It will not necessarily go out with computers, but mobile phones for many people is essential. Mobile Internet is generated based on mobile terminal, a start has a large user group. The Internet has created an economic myth, if the mobile phone users on such a large consumer groups to establish a mobile Internet platform, so widely used in corporate, commercial and rural areas, that would be to create a more earth-shaking than the miracle of the Internet.
Both have been leading for Apple, Google, or is catching up Nokia, Yahoo and many more businesses, mobile Internet is undoubtedly a feast everyone wants to participate. Mobile Internet is changing the world, of which there are boundless opportunities.

Despite Google’s open-source project manager cum compatibility Dan Morrill, claim Android platform division is to frighten the fictional story of rookie developers, but this is still an indisputable fact. There are two aspects of Android problems. First, just a year and a half, there are already 6 major releases. Regardless of how the efforts to simplify, developers, OEM, and customers have to endure many changes.
The second question is, according to Google their own information, there are still three widely used revision:
Android 2.1 highest utilization rate, but the Android Marketplace, more than half of customers use the Android 1.5 and 1.6, and this data is representative of the platform division already exists.
It would constitute a problem? Within 19 months of 6 major release is a problem. That changes in the frequency display Android players attributes. General users, this frequent change in a matter of extreme confusion and bring up the market, operating system version changed once every few months, compatibility problems are inevitable.
However, this change in frequency can not be long-term sustainability. Android leader Andy Rubin described the pace slowed down: Now our products (update) cycle, basically 1 year 2. When everything is slowly established, may eventually be reduced to 1 year 1. Because a change in the platform, the developer is difficult to catch up. I hope the developer has been able to drive innovation, and I do not want them to have to predict innovation.
While such an attitude conducive to the development of the long-term, short term there will be no significant differences too. Market fragmentation problems will not disappear, but through the prudent management of the new version of an earlier version of the Android Bu Zhiyu to be eliminated immediately.
Along with Android becoming the mainstream, the platform must also be to users, developers and OEM more certainty to water down its players attributes.
