Materials for an exploratory theory of the network society.
- The British Journal of Sociology
, 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

THE NETWORK SOCIETY: AN OVERVIEW In the last two decades of the twentieth centur y a related set of social transformations has taken place around the world. While cultures
S-FTL: An Efficient Address Translation for Flash Memory by Exploiting Spatial Locality
"... Abstract—The solid-state disk (SSD) is becoming increasingly popular, especially among users whose workloads exhibit substantial random access patterns. As SSD competes with the hard disk, whose per-GB cost keeps dramatically falling, the SSD must retain its performance advantages even with lowcost ..."

to reduce mapping table size, increase hit ratio for in-cache address translation, and minimize expensive writes to flash memory. We have conducted extensive trace-driven simulations to evaluate S-FTL and compared it with other state-of-the-art FTL schemes. Our experiments show that S-FTL can reduce
An object-aware memory architecture
, 2005
"... Despite its dominance, object-oriented computation has received scant attention from the architecture community. We propose a novel memory architecture that supports objects and garbage collection (GC). Our architecture is co-designed with a Java Virtual Machine to improve the functionality and effi ..."

and efficiency of heap memory management. The architecture is based on an address space for objects accessed using object IDs mapped by a translator to physical addresses. To support this, the system includes object-addressed caches, a hardware GC barrier to allow in-cache GC of objects, and an exposed cache
Unified Address Translation for Memory-Mapped SSDs with FlashMap
"... Applications can map data on SSDs into virtual memory to transparently scale beyond DRAM capacity, permitting them to leverage high SSD capacities with few code changes. Ob-taining good performance for memory-mapped SSD content, however, is hard because the virtual memory layer, the file system and ..."

caching efficiency. We find that this in-creases performance for applications by up to 3.32x compared to state-of-the-art SSD file-mapping mechanisms. Additionally, latency of SSD accesses reduces by up to 53.2%. 1.
How Much to Coordinate? — Optimizing In-Network Caching in Content-Centric Networks
"... Abstract—In content-centric networks, it is challenging how to optimally provision in-network storage to cache contents, so as to balance the trade-offs between the network performance and the provisioning cost. To address this problem, we first propose a holistic model for intra-domain networks to ..."

collected from a commercial 3G network in China, our results demonstrate that our caching scheme can achieve 4% to 22 % latency reduction on average over the state-of-the-art caching mechanisms. Index Terms—in-network caching, content-centric networks, coordinated caching I.
Vx32: Lightweight userlevel sandboxing on the x86
- In Proceedings of the USENIX Annual Technical Conference
, 2008
"... Code sandboxing is useful for many purposes, but most sandboxing techniques require kernel modifications, do not completely isolate guest code, or incur substantial performance costs. Vx32 is a multipurpose user-level sandbox that enables any application to load and safely execute one or more guest ..."

FlashTier: a Lightweight, Consistent and Durable Storage Cache
"... The availability of high-speed solid-state storage has introduced a new tier into the storage hierarchy. Low-latency and high-IOPS solid-state drives (SSDs) cache data in front of high-capacity disks. However, most existing SSDs are designed to be a drop-in disk replacement, and hence are mismatched ..."

In trace-based experiments, we show that FlashTier reduces address translation space by 60 % and silent eviction improves performance by up
Cache-Efficient Matrix Transposition
"... We investigate the memory system performance of several algorithms for transposing an N N matrix in-place, where N is large. Specifically, we investigate the relative contributions of the data cache, the translation lookaside buffer, register tiling, and the array layout function to the overall runn ..."
