Policy-based Management has been the subject of extensive research over the last decade. Most research work on policies has concentrated in necessary fundamental aspects such as classification, policy language, conflict detection and most recently in policy representation and storage. Little work has been done in the area of the harmonic coexistence of policies and traditional, possibly hierarc...

Distributed configuration management is intended to support the activities of projects that span multiple sites. NUCM is a testbed that we are developing to help explore the issues of distributed configuration management. NUCM separates configuration management repositories (i.e., the stores for versions of artifacts) from configuration management policies (i.e., the procedures according to whi...

An instrumentation system is a measurement-based performance evaluation abstraction. Management of an instrumentation system becomes critical when tracing is enabled on an application program that runs for an excessively long period of time. This paper presents queuing models for two instrumentation system management policies, namely, Flush One when it Fills (FOF) and Flush All when One Fills (...

In this paper, we characterize the performance of three existing memory management techniques, namely, buddy, round-robin, and first-touch policies. With existing memory management schemes, we find several cases where requests from different processors arrive at the same memory simultaneously. To alleviate this problem, we present two improved memory management policies called skew-mapping and ...
