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:
- Multiprocessor organization and system design
- Speculative multithreading
- Hardware reliability and variability
- Support for software reliability
- Low-power design
- Old Projects
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.
