SUMMARY:File Systems: Data Movement and Provenance
DESCRIPTION:Dac-Man: Data Change Management for Scientific Datasets on HPC
  Systems\n\nScientific data is growing rapidly and often changes due to in
 strument configurations, software updates, or quality assessments. These c
 hanges in datasets can result in significant waste of compute and storage 
 resources on HPC systems as downstream pipelines are reprocessed. Data cha
 nges need to be ...\n\n\nDevarshi Ghoshal, Lavanya Ramakrishnan, and Debor

 nA Year in the Life of a Parallel File System\n\nI/O performance is a crit
 ical aspect of data-intensive scientific computing.  We seek to advance th
 e state of the practice in understanding and diagnosing I/O performance is
 sues through investigation of a comprehensive I/O performance data set tha
 t captures a full year of production storage activity...\n\n\nGlenn K. Loc

  An Autonomic Data Movement Engine for Extreme-Scale Data Staging-Based In
  Situ Workflows\n\nData staging and in situ workflows are being explored e
 xtensively as an approach to address data-related costs at very large scal
 es. However, the impact of emerging storage architectures (e.g., deep memo
 ry hierarchies and burst buffers) upon data staging solutions remains a ch
 allenge. In this paper,...\n\n\nPradeep Subedi, Philip Davis, and Shaohua
