Article
This paper studies an interconnection network realization based on broadcast-and-select wavelength-division multiplexing that achieves scalable passive optical interconnection and reconfigurable network partitioning. A cluster-based configuration, where two sets of couplers individually realize the broadcast and the select functions result in flexi...
Article
A passive optical realization of large expandable shuffle networks is considered, where the general (p, k) shuffle function interconnects star-coupled clusters of time and/or wavelength multiplexed nodes. This configuration enables network partitioning into independent subnetworks that can emulate various indirect cube topologies on a virtual point...
Article
The computation of statistical indicators and indices is an integral part of algorithmic trading, and its performance becomes more prevalent in proportion to frequency and round-trip latency constraints. The HFT loop encircles data moving among traders and/or brokerages, exchanges or alternative venues, index publishers, and third party market data...
Article
Full-text available
Emerging capital market HFT is bringing strong FPGA use cases in networking, messaging, and financial computing acceleration. Stake holders include institutional and proprietary investors, exchanges, and electronic communication networks (ECNs) offering 24x7 exchange-like services, brokerages, and third-party market data providers. In both the US a...

Reconfigurability is a desirable characteristic in parallel computer architecture that supports the structural parallelism inherent to multiple parallel algorithms. This paper presents a novel approach to achieve reconfigurability via a multiple-domain wavelengthdivision multiplexed optical interconnection network. A network structure is defined to...
Article
Full-text available
Multi-domain wavelength-division multiplexing (M-WDM) is proposed as a generalization of single star-coupled WDM networks. The objective is to provide scalable interconnection schemes for different parallel computer architectures that utilize the multi-channel and tunability characteristics of photonic network devices, given their existing limitati...
Article
Full-text available
Wavelength selectivity of light sources and filters enable reconfigurable and partitionable parallel computer interconnection at low space complexity via wavelength-division multiplexing (WDM). Large scale processor networks can be built by mixing wavelength-division and passive space-division. In a multi-domain WDM network clusters of processors c...
Article
Full-text available
This paper proposes and evaluates two related fast packet switching architectures based on time-division multiplexed integrated photonic fabrics. The architectures are targeted towards low-latency inter-node switching and intra-node routing in high-speed networks. The inter-node switch achieves output packet queueing via asynchronous time-division...

This paper introduces two hierarchical optical structures for processor interconnection and compares their performance through analytic models and discrete-event simulation. Both architectures are based on wavelength division multiplexing (WDM) which enables multiple multi-access channels to be realized on a single optical fiber. The objective of t...
Article
The above paper by L. Bhuyan and D.P. Agrawal (1984) described a hierarchical, all-optical wavelength division multiplexed (WDM) network that is being built to support the communication requirements of a large distributed shared memory system. Dynamically adaptable bandwidth allocation is supported, both within and between levels of the hierarchy,...
Conference Paper
Full-text available
Passive star-coupled optical interconnects with wavelength-division multiplexing hold a strong potential for realizing flexible large-scale multicomputer networks. Virtual point-to-point regular connectivities can be defined and modified in a network with broadcast-select routing via distributed wavelength assignment to the nodes. The system size i...
Conference Paper
Full-text available
The authors study a flexible hierarchic design approach of large processor networks with distributed media access. The cluster-based interconnection combines passive metal buses and passive optical star couplers at two hierarchic levels, independently employing interleaved TDMA for conflict-free interprocessor communication. The system delay analys...
Conference Paper
This paper describes some scalable photonic switch architectures based on passive star couplers and wavelength-division multiplexing. The development of these architectures is motivated by several implications to the use of passive photonics: low access latency, large switching capacity, improved fault tolerance, and bandwidth/spatial reconfigurati...

This paper proposes a fast packet switching architecture based on time-division multiplexing a photonic space-division fabric. Asynchronous time-division multiplexing is applied to a wideband strictly nonblocking fabric to resolve destination conflicts and queue packets on outputs. High performance is achieved in terms of delay-throughput character...
Conference Paper
A photonic fast packet switch is proposed for low-latency intra-node routing in high-speed optical networks. Applications are demonstrated in telecommunication and parallel computer environments. The switch fabric is based on integrated directional-coupler technology. It has low complexity and is geometrically suitable for real-estate efficient sin...

Conference Paper
Reconfigurability is desirable in parallel computer architecture to enable efficient utilization of the inherent data communication patterns to various algorithms. Previous approaches to achieve reconfigurability have considered topology embedding, multistage permutation networks, and embedded switch arrays. This paper proposes a novel reconfigurab...
Conference Paper
This paper considers the application of time-division multiplexing as an enhancement to the performance of photonic space switching networks, breaking this tie between transmission and switching bandwidths in space-division topologies. In this way better utilization of the photonic switching bandwidth is achieved. Both synchronous and asynchronous...
