Programmable and Energy Efficient Extreme-Scale Processors

Overview:

Today, integrating 12-16 state-of-the-art cores or 10s of smaller cores on a single chip is commonplace. Since Moore's Law scaling is expected to continue for the forseeable future, processors with 1000+ cores will become possible in the future. This project is investigating techniques for supporting such extreme-scale processors. A major focus of the project is to develop new evaluation methodologies, such as multicore reuse distance analysis, for rapidly assessing extreme-scale processors. (Click here for more details on multicore RD analysis). Another focus of the project is to develop software and architectural support for extreme-scale processors, such as cache management and reconfiguration techniques, locality optimizations, and implicit synchronization techniques. Recently, the project has also begun looking at heterogeneous microprocessors in which both CPU cores and GPU cores are integrated on the same chip.
