A crucial part of any high-performance computing (HPC) system is its interconnection
network. Corning and IBM are jointly developing a demonstration interconnect based on …

We address the problem of how to exploit optics for ultrascale High Performance Computing
interconnect fabrics. We show that for high port counts these fabrics require multistage …

Low latency is a critical requirement in some switching applications, specifically in parallel
computer interconnection networks. The minimum latency in switches with centralized …

Silicon Photonic interconnects are a promising technology for scaling computing systems
into the exa-scale domain. However, there exist significant challenges in terms of optical …

In this paper, we propose a grant‐aware (GA) scheduling algorithm that can provide higher
throughput and lower latency than a conventional dual round‐robin matching (DRRM) …

High-radix switches are desirable building blocks for large computer interconnection
networks, because they are more suitable to convert chip I/O bandwidth into low latency and …

The definition of the data vortex architecture leaves broad room for decisions regarding the
exact design point required for achieving a desired performance level. A detailed simulation …

High-radix switches reduce network cost and improve network performance, especially in
large switch-based interconnection networks. However, there are some problems related to …

The combination of ever-growing data demand and the slowing down of Moore's law are
creating substantial pressure to today's Data Center Networks, forcing them to scale. On one …
