Computing Resource Execution and Management (CREAM) is a simple and lightweight system designed for efficiently manage a Computing Element (CE) in a Grid environment. It provides a well defined set of job management functionalities exposed as WebService interfaces which, together with the adoption of the open standards, guarantee a high degree of interoperability. Moreover its architecture has been designed to make CREAM a robust, scalable and fault tolerant Grid service for serving the requests coming from either a single users or a high level Grid Services. CREAM is part of the gLite midd

The Advanced Resource Connector (ARC) middleware integrates computing resources (usually, computing clusters managed by a batch system or standalone workstations) and storage facilities, making them available via a secure common Grid layer. In the past this middleware was called NorduGrid middleware, since it is being developed by the NorduGrid Collaboration. This software solution uses Grid technologies to enable sharing and federation of computing and storage resources distributed across different administrative and applica
