Query: Alchemi: A .NET-based Grid Computing Framework and its Integration into
  Global Grids   Computational grids that couple geographically distributed resources are
becoming the de-facto computing platform for solving large-scale problems in
science, engineering, and commerce. Software to enable grid computing has been
primarily written for Unix-class operating systems, thus severely limiting the
ability to effectively utilize the computing resources of the vast majority of
desktop computers i.e. those running variants of the Microsoft Windows
operating system. Addressing Windows-based grid computing is particularly
important from the software industry's viewpoint where interest in grids is
emerging rapidly. Microsoft's .NET Framework has become near-ubiquitous for
implementing commercial distributed systems for Windows-based platforms,
positioning it as the ideal platform for grid computing in this context. In
this paper we present Alchemi, a .NET-based grid computing framework that
provides the runtime 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 in addition to a grid job model. Cross-platform support is
provided via a web services interface and a flexible execution model supports
dedicated and non-dedicated (voluntary) execution by grid nodes.
