The i-acoma group, led by Professor Josep Torrellas, 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:

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.

We are involved in the NCSA Partnership for Advanced Computational Infrastructure (PACI) effort.
