The increase of the speed of computer networks paired with the ubiquity of inexpensive, yet fast and generously equipped hardware offers many organizations an affordable way to increase the available processing power. Clusters, hyperclusters and even grids, not so long ago seen only in huge datacenters, can now be found helping many small organizations in solving their computational needs. Clusterix is a truly distributed national computing infrastructure with 12 sites (static Linux clusters) located across Poland. The computing power of Clusterix can be increased by connecting additional clusters. These clusters are called dynamic because it is assumed that they will be connected to the core infrastructure in a dynamic manner, using an automated procedure. In the paper we present the design foundation of the Cumulus grid deployed at Wroclaw University of Technology, together with the method for its integration as a dynamic component in the Clusterix grid.
