Isaac Dooley

Department of Computer Science
University of Illinois at Urbana-Champaign

 Isaac Dooley is a Department of Energy High Performance Computer Science Fellow who received his M.S. Degree from the University of Illinois in Computer science and his B.S. in Mathematics and Computer Science from Birmingham-Southern College. He now is pursuing a Ph.D. at the University of Illinois. He works with his advisor Professor Kale in the Parallel Programming Laboratory.

Research:

Isaacs research interests include working with adaptive runtime systems to improve the performance and scalability of scientific simulations. He has developed portions of the ParFUM framework and the SIERRA framework. Currently ParFUM is the only known parallel framework which supports asynchronous incremental mesh modification in parallel. Additionally, Isaac is developing tools for predicting the performance of real world applications on new not-yet-existing supercomputer designs. His approach is to use partial-execution on existing processors or cycle-accurate simulators to build a model for the execution time for sequential execution blocks. The model is then used to predict the new times for all sequential execution blocks. Various types of models are being investigated, as complicated real-world applications do not fit simple models that might work well for microbenchmarks.
