The i-acoma group at UIUC

NEW: Torrellas is the Program Chair of ISCA-2012 (Call for Papers).

The i-acoma Architecture Group, led by Professor Josep Torrellas, focuses on new processor, memory, and system technologies and organizations to build novel multiprocessor computer architectures. The two main projects are:

• A novel multicore architecture for programmability: The Bulk Multicore Architecture (Communications of the ACM, December 2009). [Presentation slides].
  EE Times article that discusses the Bulk Multicore.
  Dr. Dobb's Journal discussion of the Bulk Multicore.
  This project is funded under the Intel-Microsoft Universal Parallel Computing Research Center (UPCRC).
• The next generation extreme-scale multiprocessor architecture: Thrifty: An Extreme-Scale Multiprocessor Architecture (IEEE Computer, November 2009). [Presentation slides].
  This work is part of an Intel-lead DARPA project that aims to design an Extreme-Scale computer.
  Intel blog on the DARPA project.
  This project is funded by DARPA under UHPC and DOE.

The emphasis research areas in the group are:

• Multiprocessor organization and system design
• Speculative multithreading
• Hardware reliability and variability
• Support for software reliability
• Low-power design
• Old Projects
• The FlexRAM Intelligent Memory System
• The Morphable Multithreaded Memory Tiles (M3T) architecture

We have released these software tools:

• VARIUS: A model of within-die process variation and resulting timing errors in processors for microarchitects.
• SESC: A cycle accurate architectural simulator that models a very wide set of architectures: superscalars, multiprocessors, processors in memory, and thread-level speculation.
