Download file to see previous pages 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. ...Download file to see next pages Read More

Database Architecture and Administration

...Database Architecture and Administration Evolution of Database Models The aim of this essay is to present an evolutionary history of various Database Models over the four decades of their existence. The essay attempts to list the strengths and weaknesses of each model and discuss the causes that led to their development. While databases have been used since the beginning of electronic computing, the earliest databases were custom made for organizations, difficult to operate and extremely inefficient. These file-based systems needed specific, custom-built programs to access and manage it. Since each file was isolated from others, it often resulted in redundancy and duplication of data. This took up a lot storage space and made the systems...

Effects of Human Resource Systems on Manufacturing Performance and Turnover

Most of these developments, not surprisingly, have come from communities of scholars focusing on their own particular countries or regions, be it the US (for example, Arthur, 1994; Delery and Doty, 1996; Huselid et al., 1997), the UK (for example, Brewster, 1999; Guest et al., 2003), elsewhere in Europe (for example, D’Arcimoles, 1997; Lahteenmaki et al., 1998; Roderiguez and Ventura, 2003). The difference in perspective on the value of people in organizations and the validity of HRM, particularly in non-Western Countries may be best understood in terms of the concept of locus of human value (Jackson et al., 2003).

But unless HR is in the hands of someone who is qualified by education and experience to properly give it its due implantation, HR will always be at the end of a long to-do list that seldom gets reached.  This will soon be impractical as HR is becoming a more predominant force in the workplace, ‘HR programs and processes will remain important, but, like accounting and sales, they will be even more powerful as part of the new decision science.’ (Boudreau, and Ramstad)

Colonial Architecture in Americas

American colonial architecture began during colonial rule in the 17th century. The settlers from various European countries arrived there, dwelled there and brought their own technique of architecture with them. Among them were the British, French, Spanish, Portuguese and German. European architecture became dominating in the Americas. As historians Burkholder and Johnson have pointed out, "in a remarkably short time, the conqueror's cathedrals, convents, administrative buildings, and private residences replaced the pyramids, elevated plazas, ball courts, and palaces of the indigenous elites.” (Mark A. Burkholder and Lyman L. Johnson, 2004) Thus the American architecture can be called amalgamative in its characteristic. But...

The Resource-Based View of the Firm

The RBV has gained the attention of a number of authors and practitioners who undertake the perspective that firms can improve their performance, strengthen their competitiveness (through achieving competitive advantage) and excel in markets or industries by being able to differentiate themselves on the basis of transforming their unique resources into corporate strategy.

The Resource-Based View of the firm, however, as Begermann (2006) indicates, pertains to two fundamental constructs other than the strategic management; the building of competencies and the sustainability of capabilities. However, prior to exploring these constructs, there needs to be a more thorough analysis of the RBV’s main points regarding t...
