Database Architecture for GEMLCA Resource Availability Research Paper

Database Architecture for GEMLCA Resource Availability - Research Paper Example GEMLCA or Grid Execution Management for Legacy Code Architecture is a language independent solution used to deploy existing legacy code applications as a Grid service. Any application written in any language can be deployed as a grid service without the need of even legacy code i.e. binary codes and source code. It is a computing system consisting of PC clusters. Legacy applications are deployed on these servers as grid services. Compute servers are then accessed by various grid clients for required resources. Grid host environment is used to implement service-oriented grid layer which is based on Open Grid Services Architecture (OGSA) specifications e.g. GT3, GT4, g-Lite or the OMII middleware. This layer is required to connect computer server to OSGA built grid. The selected grid should allow the grid clients to access legacy applications available in computer servers like a grid or web services. Administrators should be able to deploy new legacy applications on computer server using different job managers like Condor, Fork, PBS, etc. GEMLCA resources are consists of legacy codes which are deployed as grid services. These resources are installed on the computer server. GEMLCA Resource layer manages the interaction between Grid services and Grid Host Environment. Resource Layer is used for the following purposes: Deploying legacy applications as Grid services Querying the GEMLCA resources and get the list of available legacy applications getting the list of legacy parameters with default values and allow the user to modify these submitting legacy jobs to a job manager querying the status of previously submitted legacy jobs retrieving results from legacy applications GEMLCA Resource layer has the following three services: GLCAdmin It deploys a legacy application as a Grid service. GLCList It searches for legacy applications available over a grid. GLC Process It manages the workflow processes over Grid such as submitting a legacy application using GEMLCA and getting job status and results back.

Management Information Systems - Essay Example utes majority of trades on stock exchange, has experienced the rapid stock executions that are performed by the computers based on external input, such as related securitys price. The excessive number of executions led the system to the crash. Because of the crash in 1987, the Dow Jones Industrial Average (DJIA) crashed by five hundred and eight (508) points (approximately 22.61%). Whereas, The May 6, 2010 Flash Crash was a United States stock market crash in which the DJIA has fallen around thousand (1,000) points (approximately 9%). The Flash Crash of May 6, 2010, was not a mere technical hitch. Whereas, the Black Monday was the failure program trading, overvaluation, market psycology and illiquidity. The similarities between the two crashed are meaningful and significant. In both crashes, comparatively, there was s same response of deteriorating prices prompting more and more intense selling. However, the the system was up within minutes in the flash crash 2010, whereas, the Black Monday too much time to restore the system. But it can be stated that in the both crashes, the computer system was the main problem, however, both the crashes have their particular reasons as well. One of the main problems discussed in the case study is the poor performance of school system in America. In order to solve the problem, the data-driven information system was developed and deployed in the schools. However, it also opposed by the parents of the students by stating that the system is an unnecessary expenditure. Moreover, the parents and tutors also complained that the students spend more time on projects and creative tasks rather on course material. The teachers are enrolled in the system for their improvement, but this makes it difficult to dismiss the less effective teachers. Therefore, the system was also opposed by the teachers as they need to work hard (four hours weekly workload increased) to improve their results in the system. In general, it can be stated that any
