«Going Through Rough Times: Parallel Discrete Event Simulations -
A Physicist's Perspective»

 

Abstract:

Discrete Event Simulations (DES) are used in a large number of scientific, engineering, military, and manufacturing applications. I will introduce DES, and the idea of `virtual time' which is used in parallel DES (PDES) simulations. One important question to be addressed is the scalability of PDES algorithms, i.e. the computer simulation time required as the number of processing elements and the problem size grow. A connection between non-equilibrium surface science and the PDES `virtual time' allows questions of scalability to be addressed. For example, we have proven in any dimension that ALL conservative short-ranged PDES are scalable for the computation portion of the algorithm, independent of the specific PDES problem.  Methods related to network theory to smooth rough virtual times to make both the computation and the measurement portions of ALLshort-ranged PDES scalable will be described.
