Modern scientific applications, such as computer models for analyzing data
from particle colliders or space observatories, process data that is
exponentially growing in size. High-performance computing (HPC) centers that
support such applications are now faced with a data deluge, which can no
longer be managed using ad hoc approaches in use today. Consequently, a
fundamental reevaluation of the data management tools and techniques is
required. In this talk, I will describe a fresh approach to HPC storage
space management, especially for the center scratch space --- a high speed
storage used for servicing currently running and soon to run applications
--- which effectively treats the storage as a tiered cache and provide
comprehensive integrated storage management. I will discuss how the caching
model is achieved, and how its mechanisms are supported through just-in-time
staging and timely offloading of data. Finally, I will show how this
approach can also mitigate the effects of center storage failures. The
overall goal is to improve HPC center serviceability and resource
utilization.
