How Even Tiny Influence Can Have a Big Impact!

An influence network is a graph where each node changes its state according to a function of the states of its neighbors. We present bounds for the stabilization time of such networks. We derive a general bound for the classic “Democrats and Republicans” problem and study different model modifications and their influence on the way of stabilizing and their stabilization time. Our main contribut...

Big Chips

scaling (that is, Dennard scaling) provided three benefits: doubling of integration capacity to deliver twice the number of transistors per unit area every two years at constant price, increased transistor performance, and reduced energy per transistor. With the steady erosion of the latter two benefits, the low-hanging fruit for performance increase has been to exploit integration capacity via...

Big Chips and Beyond

.......This issue features articles on the resurgence and many implications of big chips—from cache-core tradeoffs to power to on-chip networks to clock networks and more. Guest Editors Andrew Kahng and Vijayalakshmi Srinivasan have done an excellent job of pulling together key work related to big chips. However, after a period of some consolidation in microarchitecture, big chips are but one o...

Thinking Big About Tiny Databases

Work on early tiny database systems, like TinyDB [17] and Cougar [23] has shown that a declarative approach can provide a powerful and easy to use interface for collecting data from static sensor networks. These early systems, however, have significant limitations; in particular, they are useful only for low-rate data collection applications on static sensor networks and they don’t integrate we...
