I am a Ph.D. graduate in the Department of Computer Science, George Mason University, working with Dr. Hakan Aydin. I am interested in systems and networking research, specifically, safety-critical embedded systems running on multiprocessor platforms. At present, I am trying to minimize the energy consumption by 'intelligently' distributing workload to different CPUs of a multiprocessor system that provides high reliability through standby-sparing technique. A major focus of my research is to exploit the 'heterogeneity' of asymmetric multiprocessors towards optimizing various performance objectives.
Multiprocessor systems in which, each CPU core has an associated backup or spare core. When a software or hardware fault occurs, the spare CPU can take over and re-run the task, producing fault-free results and maintaining the deadline of the original task.
Computing systems made up of multiple parallel processing modules, interconnected through high-speed network. Major challenges for these type of systems are minimizing energy consumption, reliability of the network, and overall system throughput.
Dependable computing. Systems that have multiple levels of fail-safe mechanisms to deal with transient, permanent, or intermittent faults. Extensively used in space-missions and autonomous driving technologies, they provide hard timing guarantees to the application-tasks even in the face of fault-bursts.
Control-systems built on chip-multiprocessors, specifically, heterogeneous multicore processors (HMPs). The multiple types of cores can have distinctively different power and performance characteristic while supporting a single instruction set architecture. Minimizing energy consumption for a range of different types of workload is a major challenge here.
Most popular class of systems today, and covers a wide range of devices and applications. Exploring new design possibilities, improving the reliability and efficiency of tightly coupled subsystems, minimizing energy consumption.
Many of the systems under consideration are highly conceptual and futuristic, meaning they are yet to be built practically. So we built a discreet event simulator that can mimic power and timing characteristics of big.Little systems executing periodic tasks. We continuously put effort in adding more features to it and thereby making it reflect reality more accurately.
