The Lehigh University Condor Grid is an application which can be used for High Throughput Computing. The grid composes of most public site PCs managed by the LTS. The grid works like the Beowulf Cluster except that it uses only those processors on the grid that are idle, and not being used by any user. This grid is available through any public site PC or workstation that has condor installed on it. The pool includes machines running MS Windows, Linux and Mac-OSX operating systems with different hardware configurations. Instructions for using this pool are available on this page.
