As technologies become more compact and powerful, the microprocessors within them become more prone to overheating, leading to poor performance, reduced reliability, and shorter lifetimes. Jun Yang will investigate ways of controlling temperature by proactively scheduling workloads among different processing coreswhich perform specific tasks within a processorof todays multicore processors. Current processors adopt a reactive temperature control by decreasing power flow within the entire processoreven if only one core overheats. Yangs technique instead prevents overheating by swapping a high-stress task in an overheating core with a low-stress task from a cooler core. This approach would diminish the occurrence of hotspots and maintain a temperature at which the processor can function with maximum performance and reliability. Yang focuses her research on computer architecture particularly power and thermal aware design, energy efficiency, and chip multiprocessor designs.
