© 1995 California Institute of Technology. October 4, 1995. This work was facilitated by a number of people inside and outside the California Institute of Technology. Heading the list is my thesis advisor, Stephen Taylor, whose encouragement, comments and criticisms were essential to the quality and timely completion of this work. Andy Fyfe largely implemented the Concurrent Graph Library, the applications framework into which this work was integrated. Marc Rieffel designed and implemented the initial versions of the node adaption and movement routines which were used by the load balancing code; he also wrote the necessary support routines to load balance the DSMC application. Robie Samanta Roy at the Massachusetts Institute of Technology provided insight into the PIC application, which was also targeted by this work. Alan Stagg of Cray Research, Inc., assisted in porting the Concurrent Graph Library to the Cray T3D, on which performance results were collected. Access to a 256-processor T3D was provided by the NASA Jet Propulsion Laboratory and was facilitated by Caltech. Access to a 512-node Intel Paragon was provided by the Caltech Center for Advanced Computing Research. The author was also partially supported by an NSF Graduate Research Fellowship.
