Corral is a resource provisioning tool designed to help improve the performance of loosely-coupled applications on the grid. The service is based on the concept of Condor "glideins." Glidein is a multi-level scheduling technique where Condor workers (called glideins) are submitted as user jobs via grid protocols to a remote cluster. The glideins are configured to contact a Condor central manager controlled by the user where they can be used to execute the user's jobs on the remote resources. The use of glideins can significantly improve the performance of many irregular applications, like workflows, on grid resources. Using an application-specific scheduler allows users to fine-tune scheduling policies to fit the specific needs of their application. This can reduce or eliminate many of the scheduling overheads that occur when jobs are submitted using traditional grid mechanisms. It also allows users to allocate resources once, and reuse them for many jobs, which eliminates the queueing delays that are detrimental to applications with many fine-grained tasks.
