SUMMARY:Hermes: a Multi-Tiered Distributed I/O Buffering System for HDF5
DESCRIPTION:Hariharan Devarajan (Illinois Institute of Technology, HDF Gro
 up)\n\nHigh-Performance Computing (HPC) systems’ increasing ability to run
  data-intensive problems at larger scale and resolution has driven the evo
 lution of modern storage technologies. In addition, extreme amounts of dat
 a are collected by large scientific instruments and sensor network is resu
 lting in a push for more capable storage systems. Hierarchical Data Format
  (HDF) technologies  address the problems of how to organize, access, anal
 yze, and preserve data in the face of enormous growth in size and complexi
 ty. To mitigate this I/O performance bottleneck, modern storage subsystems
  are going through extensive changes, by adding additional levels of memor
 y and storage in a hierarchy. In this work, we present Hermes: a new, hete
 rogeneous-aware, multi-tiered, dynamic, and distributed I/O buffering syst
 em for HDF5. Hermes enables, manages, and supervises I/O buffering in DMSH
 . We tested our solution on Cori and show Hermes can accelerate applicatio
 ns by 62x than the state of the buffering platform.\n\nRegistration Catego
