On the Use of In-memory Analytics Workflows to Compute eScience Indicators from Large Climate Datasets

The need to apply complex algorithms on large volumes of data is boosting the development of technological solutions able to satisfy big data analytics needs in Cloud and HPC environments. In this context Ophidia represents a big data analytics framework for eScience offering a cross-domain solution for managing scientific, multi-dimensional data. It also exploits an in-memory-based distributed data storage and provides support for the submission of complex workflows by means of various interfaces compliant to well-known standards. This paper presents some applications of Ophidia for the computation of climate indicators defined in the CLIPC project, the WPS interface used for the submission and the workflow based approach employed.
