Title:

Towards the Incorporation of Dynamic Adaptation into Operating Systems

Abstract:

In the context of the DAiSES (Dynamic Adaptability in Support of Extreme Scale) research project, which is funded by the Department of Energy Office of Science, we are investigating ways to incorporate adaptation into operating systems. Current DAiSES research activities focus on four adaptation targets: disk scheduling, virtual memory management, physical memory management, and file I/O. We have designed a new disk scheduling strategy that leverages a fair queuing discipline and implements a fair scheduling algorithm that can satisfy different performance requirements for different concurrently executing applications. Although still in the exploratory stage, our work in physical memory management focuses on the allocation of different size pages and our work in file I/O centers on parallel file systems.
