Title: How to write fast models in Swarm.
Agent-based models are by nature computationally intensive.
Finding interesting behaviors in a large space can involve parameter sweeps
over numerous variables and these variables may drive the agents in a
model for hundreds of thousands of steps. Many questions are costly
to ask and there is no getting around it.
Choosing programming techniques that fully-exploit available computer
resources can make a real difference in determining whether or not a
given agent-based model's dynamics can be considered to an adequate extent.
In my talk, I'll trace through the process of improving the performance
of a Swarm model. Topics that will be covered include:
o Constructs to avoid and their algorithmic cost
o Advanced fine-grained profiling techniques with the GNU C Library
o Java profiling techniques
o Demo of ahead-of-time native code generation:
The GCC Java frontend and Kaffe
o Common bottlenecks for Java and Objective C Swarm models
o Cache behavior
o Technologies (within Swarm and external) for facilitating parallel
parameter sweeps, and a demo
