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:

Recent Designed Architectures:

The emphasis research areas in the group are:

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.

Our research is funded by NSF, DARPA, and DOE.
