Computer Architecture

The computer architecture group at UCSD is at the cutting edge of innovation in computer architecture and systems design. Our current projects address the current "grand challenge" of computer architecture:  Finding power-efficient ways to find and exploit parallelism to continue scaling performance. We are addressing this challenge by exploring novel programming abstractions, execution strategies, micro-architectures, accelerator design, and memory and storage systems.
