Recent times have seen a strong increase in the size, scope and number of information processing tasks computers are commonly used to perform. Grids are one form of distributed computing that, generally, aim for HTC (High Throughput Computing). Grids can also be constructed to perform HPC (High Performance Computing) at a relatively low cost when compared to clusters. There currently exists open source middleware for building grids. But when such grids consist of Windows machines it is difficult to use members of the grid efficiently. This research concerns the construction of a cheap grid of Windows machines. In this paper, we describe a Windows grid that uses multiple core processors which are becoming increasingly popular.
