Scientists usually rely on workflow system to manage the complexity: simply define multiple processing steps into a single script and let the work-flow systems compile it and schedule all tasks accordingly. Numerous workflow systems have been proposed and widely used, like Galaxy, Pegasus, Taverna, Kepler, Swift, AWE, etc., to name a few examples.\n  Traditionally, scientific workflow systems work with parallel file systems, like Lustre, PVFS, Ceph, or other forms of remote shared storage systems.
