Trends in High‐Performance Interconnection Networks in the Exascale and Big‐Data Era (HiPINEB 2017)

The interconnection network plays an important role in the technological revolution brought by Exascale and Big-Data challenges to high-performance computing (HPC) systems and Datacenters. In these systems, the number of processing and storage nodes is growing signifi-cantlyinordertomeettheincreasinglyhighercomputing-powerandstoragedemands.Ontheotherhand,theoverallpowerconsumptionofthese systems must remain approximately as it is nowadays; otherwise, the cost of these systems in terms of acquisition and power consumption would be excessive. Therefore, the interconnection network must provide low latency and high-communication bandwidth, while requiring low power, otherwise becoming the bottleneck of the entire HPC system. In order to face these challenges and improve the network performance, several design aspects should be considered: network topology and connectivity, routing algorithm, reliability and fault tolerance, virtualization, congestion control, network configuration and control, development of the software stack, etc. This Special Issue of the Journal on Concurrency and Computation:PracticeandExperiencegathersseveralresearchworksrelatedtothelatestadvancesandeffortsinthedesignofhigh-performance interconnection networks, like those intended to be part of the near-future Exascale and Big-Data systems. In response to the Call-For-Papers of this Special Issue, we received very interesting submissions. Specifically, seven papers were submitted, which have been assessed by 21 reviewers, so that each paper has received three reviews. As can be seen in the list included in this editorial paper, allthereviewersareexpertsofthehighestlevel,frombothindustryandacademia,andtheircollaborationhasbeenessentialforthesuccessofthis SpecialIssue.Wewouldliketothankthereviewers,whichhaveprovidednotonlydetailedevaluationsofthesubmissionsbutalsovaluablesugges-tions to enhance them. Based on the review and assessment process performed by the reviewers, we have been able to select five papers,
