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

    Authors: José Duro, Adrián Castelló, Maria Engracia Gomez, Julio Sahuquillo, Enrique Quintana (UPV) 1 Introduction In this blog entry, we present the characterization of the network congestion for the target RED-SEA applications. This congestion is mainly due to collective communication operations, and therefore some of the optimizations for collective communications primitives (CCP) proposed in Task 3.1 of the RED-SEA project for the reduction of congestion are presented. In the context of the RED-SEA project with extreme computing and data components, parallel applications will generate large congestion due to collective operations. This means that improvements in the performance of these operations… Read more: Optimizations for collective communications primitives (CCP)
