Efficient and robust system for accessing computational resources and managing job operations is a key component of any Grid framework designed to support large distributed computing environment. Computing Resource Execution and Management (CREAM) is a simple, minimal system designed to provide efficient processing of a large number of requests for(More)
Various models of HIV infection and evolution have been considered in the literature. This paper considers a variant of the Wodarz and Nowak mathematical model, adding "aggressiveness" as a new state variable in order to quantify the strength of the virus and its response to drugs. Although the model proposed is relatively simple, simulation results suggest(More)
Contemporary Grids are characterized by a middleware that provides the necessary virtualization of computation and data resources for the shared working environment of the Grid. In a large-scale view, different middleware technologies and implementations have to coexist. The SOA approach provides the needed architectural backbone for interoperable(More)
Workflows have an increasing role in scientific applications programming and business environment development because they are an effective technology to define composition of different pieces of knowledge, both in the application domain and in the business context. However, workflows are addressed in a number of different perspectives and no consensus has(More)
