Our Research Mission
Interconnection networks are the central component of modern computer systems across a wide range of system scales. They connect processors with one another, with memories and with I/O devices both in supercomputers and on-chip; they provide the fabric for network switches and routers in data centers, and they are the system integration framework for systems-on-chip. Historically, they have been key enablers for fast messaging, scalable processing and memory architectures in parallel computing machines, or for flexible and cost-effective system integration in embedded computing platforms. Today, a key structural change overtaking computing is the move towards a low-power computing continuum spanning embedded systems, mobile devices, microservers, high-performance computing machines and data centers. Again, the success of this trend depends on the capability to bring interconnection networks into new ground. In the embedded computing domain, emerging heterogeneous parallel computing architectures require a hierarchy of interconnection fabrics, providing efficient support for complex workloads such as multi-programmed and mixed-criticality ones. At the opposite side of the computing spectrum, architectures inspired by the same concepts (parallelism, heterogeneity) are running the race to exascale computing at full speed, but only interconnection networks with disruptive features in terms of bandwidth, energy-per-bit and seamless scalability can make them hit the target. The mission of this research group is to stay at the forefront of system innovation at different scales (embedded systems, microservers, high-performance computing) by leveraging the enabling features of communication architectures and technologies.
