SUMMARY:Seeing the Trees for the Forest:  Describing HPC Filesystem Trees 
 with the Grand Unified File-Index (GUFI)
DESCRIPTION:Jenna Kline (Ohio State University, Los Alamos National Labora
 tory (LANL))\n\nHigh performance computing (HPC) filesystems are extremely
  large, complex, and difficult to manage with existing tools. It is challe
 nging for HPC administrators to describe the current structure of their fi
 lesystems, predict how they will change over time, and the requirements fo
 r future filesystems as they continue to evolve. Previous studies of files
 ystem characteristics largely predate the modern HPC filesystems of the la
 st decade. The Grand Unified File Index (GUFI) was used to collect the dat
 a used to compute the characteristics of six HPC filesystems indexes from 
 Los Alamos National Laboratory (LANL) representing 2.8 PB of data, contain
 ing 36 million directories and 600 million files. We present a methodology
  using GUFI to characterize the shape of HPC filesystems to help system ad
 ministrators to understand their key characteristics.\n\nThis document has
