The increasing amount of data being collected from simulations, instruments and sensors creates challenges for existing e-Science infrastructure. In particular, it requires new ways of storing, distributing and processing data in order to cope with both the volume and velocity of the data. The University of Queensland has recently designed and deployed MeDiCI, a data fabric that spans the metropolitan...
Relative debugging traces software errors by comparing two executions of a program concurrently - one code being a reference version and the other faulty. Relative debugging is particularly effective when code is migrated from one platform to another, and this is of significant interest for hybrid computer architectures containing CPUs accelerators or coprocessors. In this paper we extend relative...
In this paper, we present a framework that enables scientists to steer computations executing over large-scale grid computing environments. By using computational steering, users can dynamically control their simulations or computations to reach expected results more efficiently. The framework supports steerable applications by introducing an asynchronous iterative MapReduce programming model that...
