SUMMARY:Using Darshan and CODES to Evaluate Application I/O Performance
DESCRIPTION:Harsh Khetawat (North Carolina State University), Christopher 
 Zimmer (Oak Ridge National Laboratory), Frank Mueller (North Carolina Stat
 e University), and Sudharshan Vazhkudai and Scott Atchley (Oak Ridge Natio
 nal Laboratory)\n\nBurst buffers have become increasingly popular in HPC s
 ystems, allowing bursty I/O traffic to be serviced faster without slowing 
 down application execution. The ubiquity of burst buffers creates opportun
 ities for studying their ideal placement in the HPC topology. Furthermore,
  the topology of the network interconnect can also affect the performance 
 of the storage hierarchy for different burst buffer placement schemes.  To
  that end, we create a reproducible framework that allows individual cente
 rs to develop their own models and evaluate performance based on their wor
 kload characteristics. \nWe use CODES to create models that simulate the n
 etwork and storage layers of an HPC system and Darshan traces for I/O repl
 ay. We augment the Darshan traces with synchronization primitives, and all
 ow multi-dimensional scaling of traces to represent future workload charac
 teristics. Finally, we evaluate the effect of network topology, storage ar
 chitecture, and application I/O patterns on overall I/O performance.\n\nRe
