The evolution of Coda
M. Satyanarayanan
Pages: 85-124
DOI: 10.1145/507052.507053
Failure-resilient, scalable, and secure read-write access to shared information by mobile and static users over wireless and wired networks is a fundamental computing challenge. In this article, we describe how the Coda file system has evolved to...

Measuring system normality
Hårek Haugerud, Sigmund Straumsnes, Trond Reitan, Mark Burgess
Pages: 125-160
DOI: 10.1145/507052.507054
A comparative analysis of transaction time-series is made, for light to moderately loaded hosts, motivated by the problem of anomaly detection in computers. Criteria for measuring the statistical state of hosts are examined. Applying a scaling...

Let caches decay: reducing leakage energy via exploitation of cache generational behavior
Zhigang Hu, Stefanos Kaxiras, Margaret Martonosi
Pages: 161-190
DOI: 10.1145/507052.507055
Power dissipation is increasingly important in CPUs ranging from those intended for mobile use, all the way up to high-performance processors for highend servers. Although the bulk of the power dissipated is dynamic switching power, leakage power is...
