Current Projects

• The Stampede Project, i.e., NSF High Performance System Acquisition: Enabling, Enhancing, and Extending Petascale Computing for Science and Engineering (2013-2017): This research contributes to the technology insertion efforts of the Stampede project. Working with the Stampede operations team, these efforts, which include the use and study of the computation and communication resources of Stampede, will insure successful support for computer science research on the system (a frequent criticism of large-scale production systems). (Funded by National Science Foundation through the University of Texas at Austin, Texas Advanced Computing Center)
• Enabling Battlefield Decision-Making using Tactical Cloudlets (2011-2016): Given a cloudlet that consists of static and mobile devices connected via a wireless Mobile Ad Hoc Network (MANET), this research aims to study how to (a) reduce the energy consumption associated with its operation and (b) increase the number of jobs that meet their solution deadlines. This includes the migration of applications to mobile computing devices and the employment of efficient and cooperative resource provisioning, scheduling, and communication.

Past Projects

• SHiPPER: Spreading High-Performance computing Participation in undergraduate Education and Research.
• I/O Coordination: Through provision of differentiated I/O service and opportunistic coordination of checkpoint/restart, increase meaningful utilization of computing resources and enhance system performance. (Funded by the DoE Office of Science)
• Specifying Field-Deployable and On-Board Computer Systems: Accelerate infusion of new technologies into on-board and field-deployable systems and, thus, enhance mission performancy by increasing computational capabilities, speeding-up application execution, and migrating functionality. (Funded by the Army Higher Performance Computing Center, AHPCRC)
• DAiSES: Dynamic Adaptivity in Support of Extreme Scale.
• PCAT: Performance Counter Assessment.
• PLS²: Performance of Large-Scale Parallel Systems.
• STEM Outreach: Gathering, modifying and creating resources to motivate middle school students to learn.
