Abstract—High Performance Computing (HPC) provides support to run advanced application programs efficiently. Java adaptation in HPC has become an apparent choice for new endeavors, because of its significant characteristics. These include object-oriented, platform independent, portable, secure, built-in networking, multithreading, and an extensive set of Application Programming Interfaces (APIs). Consequently multi-core systems and multi-core programming tools are becoming popular. However, today
Apache Hadoop is an open-source software framework for storage and large scale processing of data-sets on clusters of commodity hardware. Hadoop, an Apache top-level project is built and used by a global community of contributors and users. Rather than relying on hardware to deliver high-availability, the library is designed to detect and handle failures at the application layer itself. It delivers a highly-available service on top of a cluster of computers, each of which may be prone to failures
Relational Database Management System Oracle provides a flexible RDBMS called Oracle7. Using its features, you can store and manage data with all the advantages of a relational structure plus PL/SQL, an engine that provides you with the ability to store and execute program units. The server offers the options of retrieving data based on optimization techniques. It includes security features that control how a database is accessed and used. Other features include consistency and protection of data
program that translates source code, instructions in a program written by a software engineer, into object code, those same instructions written in a language the computer's central processing unit (CPU) can read and interpret. Software engineers write source code using high level programming languages that people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low level language called machine code. Compiler: How It Works
settings. Agents are found in computer operating systems, networks, databases, and so on. Now the question arises that what properties do these agents share that compose the core of being an agent? Agents have the ability to interact with their execution environment, and to act asynchronously and autonomously upon it. No one is required either to deliver information to the agent or to consume any of its output. The agent simply acts continuously in pursuit of its own goals. In contrast to software
Cloud computing involves a lot of concepts and technologies. Companies and corporations such as Amazon, Google and Microsoft are providing services following the logic of computational infrastructure cloud computing, with Amazon the pioneer in providing and marketing infrastructure of this kind. The academic community has also shown interest in cloud computing, and some work has been directed to improvements in aspects of performance, security, usability, implementation and reliability of the system
1. Compare two criteria or characteristics using Visual Basic and Visual C++. Readability. Visual Basic is a programming language that can be easily read. Most constructs resemble plain English words and phrases. It also has low feature multiplicity. To increment a variable one must write: i = i + 1. Visual C++ has several ways of doing it though with slightly different meanings: i = i + 1 or i +=1 or i++ or ++i. This lowers the readability of Visual C++. Visual Basic still retains the 'goto'
