Software Available:

• "SESC: A Simulator of Superscalar Multiprocessors and Memory Systems with Thread-Level Speculation Support".
  SESC is a multiprocessor simulator with support for thread-level speculation.
• "Augmint: A Multiprocessor Simulation Environment for Intel x86 Architectures".
  Augmint is a multiprocessor tracing and evaluation package that runs on Intel x86 machines.

Research Interests:

Professor Torrellas leads The i-acoma Group, which focuses on new processor, memory, and system technologies and organizations to build novel multiprocessor computer architectures. The goal is to design high-performance multiprocessor computers that are very easy to program, inexpensive, and built out of commodity components.

The main emphasis is on several areas:

• 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

Professor Torrellas is also involved in the related project The Polaris parallelizing compiler.

Currently Teaching:

CS533: Parallel Computer Architectures.
