Technical Perspective: Isolating a Matching When Your Coins Go Missing

Whether there exists a deterministic parallel algorithm for bipartite matching remains an outstanding question at the frontiers of our understanding of the role of randomness in computation. The question has been (nearly) recently resolved in "A Deterministic Parallel Algorithm for Bipartite Perfect Matching."

Libraries Considered Hazardous

Libraries of the future cannot merely be catalogs of digital content. The objects in the digital library will need to interact in some fashion so that truth value of their contents can be adjusted as new knowledge becomes available.

Technical Perspective: To Do or Not To Do: Extending SQL with Integer Linear Programming?

"Scalable Computation of High-Order Optimization Queries," by Brucato et al., makes a case for marrying the well-established paradigms of constrained optimization (specifically ILP) and traditional SQL querying.

Scalable Computation of High-Order Optimization Queries

We present a complete system that supports package queries, a new query model that extends traditional database queries to handle complex constraints and preferences over answer sets, allowing the declarative specification and efficient evaluation of a significant class of constrained optimization problems—ILP—within a database.

Distributed Strategies for Computational Sprints

We describe a computational sprinting architecture in which many, independent chip multiprocessors share a power supply and sprints are constrained by the chips' thermal limits and the rack's power limits.
