      Special Issue on Trends in High-Performance Interconnection Networks
                  in the Exascale and Big-Data Era

                  Wiley Journal of Concurrency and 
                Computation: Practice and Experience

By the year 2023, High-Performance Computing (HPC) Systems are expected to break the performance barrier of the Exaflop (10^18 FLOPS) while their power consumption is kept at current levels (or incremented marginally), what is known as the Exascale challenge. 
In addition, more storage capacity and data-access speed is demanded to HPC clusters and datacenters to manage and store huge amounts of data produced by software applications, what is known as the Big-Data challenge. Indeed, both the Exascale and Big-Data 
challenges are driving the technological revolution of this decade, motivating big research and development efforts from industry and academia. In this context, the interconnection 
network plays an essential role in the architecture of HPC systems and datacenters, as the number of processing or storage nodes to be interconnected in these systems is very likely to grow significantly to meet the higher computing and storage demands. Besides, the capacity of the network links is expected to grow, as the roadmaps of several interconnect standards forecast. Therefore, the interconnection network should provide a high 
communication bandwidth and low latency, otherwise the network will become the bottleneck of the entire system. In that regard, many design aspects are considered when it comes to improve the interconnection network performance, such as topology, routing algorithm, power consumption, reliability and fault tolerance, congestion control, programming models, control software, etc.

All researchers and professionals, both from industry and academia, working in the area of interconnection networks for scalable HPC systems and Datacenters, and especially those 
involved in Exascale performance and Big-Data, are encouraged to submit a paper to this special issue.


The list of topics covered by this Special Issue includes, but is not limited to, the following:

* Interconnect architectures and network technologies for high-speed, low-latency interconnects.
* Scalable network topologies, suitable for interconnecting a huge number of nodes.
* Power saving policies in the interconnect devices and network infrastructure, both at software and hardware level.
* Emerging ideas, work-in-progress and early, high-impact achievements.
* Good practices in the configuration of the network control software.
* Network communication protocols: MPI, RDMA, Hadoop, etc.
* APIs and support for programming models.
* Routing algorithms.
* Quality of Service (QoS).
* Reliability and Fault tolerance.
* Load balancing and traffic scheduling.
* Network Virtualization.
* Congestion Management.
* Applications and Traffic characterization.
* Modeling and simulation tools.
* Performance Evaluation.

Note that papers focused on topics that are too far from the design, development and configuration of high-performance interconnects for HPC systems and Datacenters (e.g., mobile networks, intrusion detection, peer-to-peer networks or grid/cloud computing) will be automatically considered as out of scope and rejected without review.


Deadline for submissions:    Extended to July 28 (hard deadline)

Deadline for revised papers: October 7, 2016
Final decision notification: October 23, 2016
