My research is in the general area of parallel and distributed computing. Current topics center around power and performance in high-performance computing, including:
Current Projects
Exascale Computing Project (ECP) Active
Investigating power constraints in task-based parallel programs targeting future exascale machines.
Project page →Zero-S Environment Active
Investigating the interaction of hardware features and HPC run-time systems and applications.
Project page →Inter-Job Optimization Active
Developing models and run-time techniques for inter-job optimization aimed at exascale systems.
Project page →Past Projects
Cloudster Past
Techniques for cost-effective execution of HPC applications on the cloud.
Project page →Hobbes Past
OS support for extreme-scale systems (joint with Sandia, UNM, and others).
