Research Interests:
My research interests lie in the areas of:
- Scalable storage performance and reliability;
- Operating and distributed systems;
- Data analysis and modeling
- Reimagine file systems as transient, light-weight services
that applications can instantiate, scale, and optimize on-demand. The
goal is to propose a (timely!) alternative to parallel file
systems with fully synchronous namespaces, which will remain performant
as we transition to exascale systems and beyond.
- Develop efficient mechanisms that turn the OS into a gray
box. A step in that direction is Duet [4], a framework that notifies
processes when data of interest becomes cache-resident. This allows
groups of processes with overlapping data accesses to adjust their
workflows in order to improve their collective efficiency. Duet has been
used to improve the efficiency of maintenance tasks [4], job schedulers
[5], and file system monitoring tools [1].
- Discover and fix pain points in systems through data analysis and modeling of field data. Some examples: improving the reliability of enterprise backup systems [2, 5], characterizing the effect of temperature on the reliability of datacenter hardware [6, 8], and mitigating the impact of maintenance work by predicting when a storage device is expected to be idle [7].
