SUMMARY:SimFS: A Simulation Data Virtualizing File System Interface
DESCRIPTION:ACM Student Research Competition, Poster\nTech Program Reg Pas
 s, Exhibits Reg Pass\n\nSimFS: A Simulation Data Virtualizing File System 
 Interface\n\nDi Girolamo\n\nIn the big (simulation) data era, simulations 
 often produce petabytes of data to be stored in parallel filesystems or la
 rge-scale databases. This data is accessed, often by thousands of analysts
  and scientists, over the course of decades. However, storing these volume
 s of data for long time periods of time is not cost effective and, in some
  cases, practically impossible. \n\nSimFS transparently virtualizes the si
 mulation output, relaxing the storage requirements and re-simulating missi
 ng data on-demand. SimFS monitors the analysis access pattern in order to 
 decide (1) which data to store and (2) apply prefetching techniques to imp
 rove the analysis performance. SimFS enables a trade-off between on-disk s
 olutions, where all the simulation data is stored on disk, and in-situ, wh
 ere no data is stored and analyses are always coupled with simulations.  O
 verall, by exploiting the growing computing power and relaxing the storage
  capacity requirements, SimFS offers a viable path towards exa-scale simul
 ations.
