The network-on-chip (NoC) is a primary shared resource that serves as the primary communication substrate in a multicore system. As core counts continue to increase and applications become increasingly data-intensive, the network load will also increase, leading to more congestion in the network. In this talk, I will present Heterogeneous Adaptive Throttling (HAT), a new application-aware throttling technique that reduces congestion to improve system performance in NoC based multicore systems.


Kevin Chang is a second year PhD student in the Electrical and Computer Engineering Department at Carnegie Mellon University, working with Professor Onur Mutlu. He received his B.S./M.S. in Electrical and Computer Engineering in 2011, and his research interests encompass computer archi-tecture with a focus on networks-on-chip and memory subsystems.
