Distributed algorithms for ultrasparse spanners and linear size skeletons
We present efficient algorithms for computing very sparse low distortion spanners in distributed networks and prove some non-trivial lower bounds on the tradeoff between time, spar...

An optimal maximal independent set algorithm for bounded-independence graphs
We present a novel distributed algorithm for the maximal independent set (MIS) problem.1 On bounded-independence graphs (BIG) our deterministic algorithm finishes in O(log n) time,...

Adaptive progress: a gracefully-degrading liveness property
We introduce a simple liveness property for shared object implementations that is gracefully degrading depending on the degree of synchrony in each run. This property, called adapt...

Distributed computing as a virtual supercomputer: Tools to run and manage large-scale BOINC simulations
Distributed computing (DC) projects tackle large computational problems by exploiting the donated processing power of thousands of volunteered computers, connected through the Int...
