Interconnection Networks for High-Performance Parallel Systems

Infiniband NetworkInterconnection networks are a key element in High-Performance Computing (HPC) Clusters and Datacenters in the Exascale and Big-Data Era. They must offer high communication bandwidth and low latency to cope with the requirements of Applications, in order not to be the bottleneck of the entire HPC system. Actually, the path for designing the future interconnect technology has to face challenges like scalability, efficiency, heterogeneity, resiliency, virtualization, cost and power consumption.

The RAAP group has been carrying research in interconnection networks for more than 15 years, achieving significant insights which have been published in relevant conferences and journals, and incorporated to commercial products as well.
