Oceanstore: An architecture for global-scale persistent storage
, 2000
"... OceanStore is a utility infrastructure designed to span the globe and provide continuous access to persistent information. Since this infrastructure is comprised of untrusted servers, data is protected through redundancy and cryptographic techniques. To improve performance, data is allowed to be cac ..."

to be cached anywhere, anytime. Additionally, monitoring of usage patterns allows adaptation to regional outages and denial of service attacks; monitoring also enhances performance through pro-active movement of data. A prototype implementation is currently under development. 1
Cache Decay: Exploiting Generational Behavior to Reduce Cache Leakage Power
- in Proceedings of the 28th International Symposium on Computer Architecture
, 2001
"... Power dissipation is increasingly important in CPUs ranging from those intended for mobile use, all the way up to highperformance processors for high-end servers. While the bulk of the power dissipated is dynamic switching power, leakage power is also beginning to be a concern. Chipmakers expect tha ..."

leakage. We discuss policies and implementations for reducing cache leakage by invalidating and “turning off ” cache lines when they hold data not likely to be reused. In particular, our approach is targeted at the generational nature of cache line usage. That is, cache lines typically have a flurry
A scheduling model for reduced CPU energy
- ANNUAL SYMPOSIUM ON FOUNDATIONS OF COMPUTER SCIENCE
, 1995
"... The energy usage of computer systems is becoming an important consideration, especially for batteryoperated systems. Various methods for reducing energy consumption have been investigated, both at the circuit level and at the operating systems level. In this paper, we propose a simple model of job s ..."

Mega: molecular evolutionary genetic analysis software for microcomputers
- CABIOS
, 1994
"... A computer program package called MEGA has been developed for estimating evolutionary distances, reconstructing phylogenetic trees and computing basic statistical quantities from molecular data. It is written in C+ + and is intended to be used on IBM and IBM-compatible personal computers. In this pr ..."

, new algorithms of branch-and-bound and heuristic searches are implemented. In addition, MEGA computes statistical quantities such as nucleotide and amino acid frequencies, transition/transversion biases, codon frequencies (codon usage tables), and the number of variable sites in specified segments
A scaled conjugate gradient algorithm for fast supervised learning
- NEURAL NETWORKS
, 1993
"... A supervised learning algorithm (Scaled Conjugate Gradient, SCG) with superlinear convergence rate is introduced. The algorithm is based upon a class of optimization techniques well known in numerical analysis as the Conjugate Gradient Methods. SCG uses second order information from the neural netwo ..."

Back to Bentham? Explorations of Experienced Utility
- QUARTERLY JOURNAL OF ECONOMICS
, 1997
"... Two core meanings of “utility” are distinguished. “Decision utility” is the weight of an outcome in a decision. “Experienced utility” is hedonic quality, as in Bentham’s usage. Experienced utility can be reported in real time (instant utility), or in retrospective evaluations of past episodes (remem ..."

An adaptive, nonuniform cache structure for wire-delay dominated on-chip caches
- In International Conference on Architectural Support for Programming Languages and Operating Systems
, 2002
"... Growing wire delays will force substantive changes in the designs of large caches. Traditional cache architectures assume that each level in the cache hierarchy has a single, uniform access time. Increases in on-chip communication delays will make the hit time of large on-chip caches a function of a ..."

of a line's physical location within the cache. Consequently, cache access times will become a continuum of latencies rather than a single discrete latency. This nonuniformity can be exploited to provide faster access to cache lines in the portions of the cache that reside closer to the processor
Caching in the Sprite Network File System
- ACM Transactions on Computer Systems
, 1988
"... The Sprite network operating system uses large main-memory disk block caches to achieve high performance in its file system. It provides non-write-through file caching on both client and server machines. A simple cache consistency mechanism permits files to be shared by multiple clients without dang ..."

danger of stale data. In order to allow the file cache to occupy as much memory as possible, the file system of each machine negotiates with the virtual memory system over physical memory usage and changes the size of the file cache dynamically. Benchmark programs indicate that client caches allow
New Directions in Traffic Measurement and Accounting
, 2001
"... Accurate network traffic measurement is required for accounting, bandwidth provisioning, and detecting DOS attacks. However, keeping a counter to measure the traffic sent by each of a million concurrent flows is too expensive (using SRAM) or slow (using DRAM). The current state-of-the-art (e.g., Cis ..."

showing that a number of simple solutions based on cached counters and classical sampling do not work, we describe two novel and scalable schemes for this purpose which take a constant number of memory references per packet and use a small amount of memory. Further, unlike NetFlow estimates, we have
Drowsy Caches: Simple Techniques for Reducing Leakage Power
- PROC. 29TH INT’L SYMP. COMPUTER ARCHITECTURE
, 2002
"... On-chip caches represent a sizable fraction of the total power consumption of microprocessors. Although large caches can significantly improve performance, they have the potential to increase power consumption. As feature sizes shrink, the dominant component of this power loss will be leakage. Howev ..."

. However, during a fixed period of time the activity in a cache is only centered on a small subset of the lines. This behavior can be exploited to cut the leakage power of large caches by putting the cold cache lines into a state preserving, low-power drowsy mode. Moving lines into and out of drowsy state
