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.

Technical Perspective: How Economic Theories Can Help Computers Beat the Heat

The authors of "Distributed Strategies for Computational Sprints" bring the rich theory of allocating scarce resources to the challenge of managing computational sprinting in datacenters.

Scalable Computation of High-Order Optimization Queries

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…

Distributed Strategies for Computational Sprints

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.
