The complexity of verifying memory coherence
The general problem of verifying coherence for shared-memory multiprocessor executions is NP-Complete. Verifying memory consistency models is therefore NP-Hard, because memory con...

Complex Dynamics and Financial Fragility in an Agent Based Model
In this paper, we model an agent-based economy in which heterogeneous agents (firms and a bank) interact in the financial markets. The heterogeneity is due to the balance sheet ...

Generalized Langton's Ant: Dynamical Behavior and Complexity
Langton’s ant is a simple discrete dynamical system, with a surprisingly complex behavior. We study its extension to general planar graphs. First we give some relations between c...

Circuit Complexity Reduction for Symbolic Analysis of Analog Integrated Circuits
This paper presents a method to reduce the complexity of a linear or linearized (small-signal) analog circuit. The reduction technique, based on quality-error ranking, can be used...

Using PI/OT to Support Complex Parallel I/O
This paper describes PI/OT, a template-based parallel I/O system. In PI/OT, I/O streams have annotations associated with them that are external to the source code. These annotatio...
