The Impact of Emerging Technologies on the Design of Computer Systems

The overall goal of this group’s work is to develop computer systems that satisfy a desired set of constraints. These constraints typically require non-obvious trade-offs in performance, power consumption, cost, and reliability. The researchers are particularly interested in how changes in the underlying technology, such as the trend towards smaller feature sizes in VLSI circuits and new types of technologies, affects how computer systems will be designed in the future. They are working on several interrelated projects in this broad area, including the development of techniques to automatically classify the benchmark programs used to evaluate the performance of computer systems, techniques to statistically evaluate large design spaces, and studying how spintronics components might be used to design computer systems. MSI resources are particularly valuable for performing the very large number of simulations needed to evaluate computer design trade-offs. This group is also actively developing highly parallel applications for large-scale systems with heterogeneous accelerators, such as GPUs, and analyzing the performance trade-offs in these systems.
