Research Interests:
Professor Torrellas leads The i-acoma Group, which focuses on new processor, memory, and system technologies and organizations to build novel computer architectures. The goal is to design high-performance computers that are very easy to program, inexpensive, and built out of commodity components.The main emphasis is on several areas:
- Architecture and software support for Thread Level Speculation (TLS)
- Architectural design for reliability, debuggability, and fault recovery
- Reconfigurable architectures (See The Morphable Multithreaded Memory Tiles (M3T) architecture)
- Architectures that integrate many processor cores and substantial memory on a chip (See The FlexRAM Intelligent Memory System)
- Architectural techniques for energy management in advanced chips
Professor Torrellas is also involved in the related project The Polaris parallelizing compiler.
