But it cannot leverage universally accessible cloud-based infrastructures like DropBox, as those offer limited interfaces and inadequate levels of access bandwidth. We present the Scibox cloud facility for online sharing scientific data. It uses standard cloud storage solutions, but offers a usage model in which high end codes can access the cloud via the same ADIOS APIs they already use for their I/O actions, thereby naturally coupling data generation with subsequent data analytics. Extending current ADIOS IO methods, with Scibox, data upload/download volumes are controlled via D(ata)R(reduction)-functions stated by end users and applied at the data source, before data is moved, with further gains in efficiency obtained by combining DR-functions to move exactly what is needed by current data consumers. Scibox is evaluated with science applications, e.g., GTS demonstrating the potential for ubiquitous data access with substantial reductions in network traffic.
