Average-case tractability of manipulation in voting via the fraction of manipulators
Recent results have established that a variety of voting rules are computationally hard to manipulate in the worst-case; this arguably provides some guarantee of resistance to man...

A linear-time algorithm for optimal barrier placement
We want to perform compile-time analysis of an SPMD program and place barriers in it to synchronize it correctly, minimizing the runtime cost of the synchronization. This is the b...

Social creativity: turning barriers into opportunities for collaborative design
Design is a ubiquitous activity. The complexity of design problems requires communities rather than individuals to address, frame, and solve them. These design communities have to...

A Practical Approach to the Rating of Barrier Algorithms Using the LogP Model and Open MPI
Large–scale parallel applications performing global synchronization may spend a significant amount of execution time waiting for the completion of a barrier operation. Conseque...

Insertion Tree Phasers: Efficient and Scalable Barrier Synchronization for Fine-Grained Parallelism
This paper presents an algorithm and a data structure for scalable dynamic synchronization in fine-grained parallelism. The algorithm supports the full generality of phasers with d...
