Project Summary |
|
|
Next-generation distributed applications will involve storing,
transporting, and processing multiple types of information, such as
textual and numeric data, images, audio, video, and animation. Due to
inherent differences in data characteristics (e.g., size, format,
tolerance to errors, real-time requirements), these applications
impose diverse performance requirements on the underlying file
systems.
The main objective of this project is to design, implement
and evaluate file systems that can efficiently support these emerging
applications. To achieve this objective, we have developed:
-
Application-specific policies that can align the service provided by
the file system with application requirements
-
Mechanisms that enable their coexistence in a file system.
Symphony is a prototype file system that instantiates our
research findings.
