Network Interconnect for Exascale Systems

Network: the next big bottleneck?

Network interconnect is the backbone of a supercomputer, connecting together the compute nodes

To reach the exascale with a reasonable power consumption, exascale supercomputers will include a huge number of nodes, and they will be hybrid nodes integrating GPUs and CPUs

Integrating heterogeneous nodes requires a smarter interconnect, with additional features to accelerate connectivity between servers and storage

Those are the challenges that RED-SEA is tackling to design the network interconnect that will power future European Exascale systems

    An Open-Source Integrated Solution to Address the Simulator Gap for Parallel Heterogeneous Systems Authors: Nikolaos Tampouratzis (EXAPSYS), Yannis Papaefstathiou (EXAPSYS). Nowadays, highly parallel and distributed computing systems (i.e., Cloud and HPC systems) are growing in capability at an extraordinary rate, incorporating processing systems that vary from simple microcontrollers to high performance units connected with each other through numerous networks. One of the main problems the designers of such systems face is the lack of simulation tools that can offer realistic insights beyond simple functional testing, such as the actual performance of the nodes, accurate overall system timing, power/energy estimations, and […]
