The simulation of Cyberinfrastructure systems has been actively pursued for several decades. The goal has been to develop methods and software to allow researchers in the field to perform perfectly controllable, observable and reproducible experiments for arbitary platform and application scenarios. The two key concerns with simulation are accuracy and scalability, and many approaches have been proposed and implemented to address these concerns in different ways.  In this presentation we discuss the need for simulators of Cyberinfrastructure systems, the challenges involved for making these simulators accurate and scalable, introduce the simulation calibration problem as a way to resolve these challenges, and present recent work that seeks to solve this problem.

Dr. Henri Casanova is a Professor in the Information and Computer Science Dept. at the University of Hawaii at Manoa. His research is in the area of high performance computing, with a particular focus on the scheduling and the simulation of parallel and distributed applications.  He obtained his B.S. from the Ecole Nationale Superieure d’Electronique, d’Electrotechnique, d’Informatique et d’Hydraulique de Toulouse, France in 1993, his M.S. from the Universite Paul Sabatier, Toulouse, France in 1994, and his Ph.D. from the University of Tennessee, Knoxville in 1998.
