INTRODUCTION
Grid computing is form of networking unlike conventional network that focus on communication among devices.
Grid computing is a method that connects the power of many computers in network to solve problems. It requires a large numbers of processing cycles and involving huge amount of data.
For example, In grid computing pcs , servers and workstations are linked together so that computing capacity is never wasted.
It is a distributed computing taken to the next evolutionary level.
The Goal of grid computing is to create the illusion of a simple large and powerful self -managing virtual computer out of large collection of connected heterogeneous system sharing various combinations of resources.
Grid computing is a way to enlist large no. of machines to work on multipart computational problem such as circuit analysis, mechanical design, special effects or any big project.
It connects a diverse number of machines and other resources to rapid processes to solve problem beyond an organization's available capacity.
Once a proper infrastructure established by resource brokers, a user will have access to a virtual computer that is reliable and adaptable to the users. For this, there must be standard for grid computing that will allow a secure and robust infrastructure to be built.
Standards such as Open Grid Services Architecture (OGSA) and tools such as Alchemi provides the necessary framework.
COMPARISON OF GRID COMPUTING WITH CONVENTIONAL COMPUTING
“Distributed” or “grid” computing in general is a special type of Parallel computing that relies on complete computers (with onboard CPUs, storage, power supplies, network interfaces, etc.) connected to a network(private, public or the Internet) by a conventional network Interface, such as Ethernet. This is in contrast to the traditional notion of a supercomputer, which has many processors connected by a local high-speed computer bus.
ALCHEMI INTRODUCTION
We have developed Alchemi, a .NET based grid computing framework that provides run-time machinery and programming environment required to construct desktop grids and develop grid applications. It allows flexible application composition by supporting an object-oriented grid application programming model .
The alchemi grid computing framework was conceived with the aim of making grid construction and development of grid software as easy as possible without. sacrificing flexibility,scalibility,relibility and extensibility.
