Scalable Computation of Dynamic Flow Problems via Multimarginal Graph-Structured Optimal Transport

Isabel Haasler

In this work, we develop a new framework for dynamic network flow pro-blems based on optimal transport theory. We show that the dynamic multicommodity minimum-cost network flow problem can be formulated as a multimarginal optimal transport problem, where t ...

IIBLAST: Speeding Up Commercial FPGA Routing by Decoupling and Mitigating the Intra-CLB Bottleneck

Mirjana Stojilovic, Stefan Nikolic, Shashwat Shrivastava

We identified that in modern commercial FPGAs, routing signals from the general interconnect to the configurable logic blocks (CLBs) through a very sparse input interconnect block (IIB) represents a significant runtime bottleneck. This is despite academic ...

Optimization Opportunities in RRAM-based FPGA Architectures

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Xifan Tang

Static Random Access Memory (SRAM)-based routing multiplexers, whatever structure is employed, share a common limitation: their area, delay and power increase linearly with the input size. This property results in most SRAM-based FPGA architectures ...

A High-performance FPGA Architecture Using One-Level RRAM-based Multiplexers

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Xifan Tang

Resistive Random Access Memory (RRAM)-based routing multiplexers, built using a one-level structure, are significantly more delay efficient than state-of-art SRAM-based implementations thanks to their lower achievable on-state resistance. In addition, the ...

Space lower bounds for low-stretch greedy embeddings

Christos Kalaitzis

Greedy (geometric) routing is an important paradigm for routing in communication networks. It uses an embedding of the nodes of a network into points of a space (e.g., R-d) equipped with a distance function (e.g., the Euclidean distance l(2)) and uses as a ...

Wireless Network Simplification: The Gaussian N-Relay Diamond Network

Christina Fragouli

We consider the Gaussian N-relay diamond network, where a source wants to communicate to destination node through a layer of N-relay nodes. We investigate the following question: what fraction of the capacity can we maintain using only k out of the N avail ...

On the efficiency of routing in sensor networks

Florian Huc

In sensor networks, a key efficiency measure for routing protocols is the stretch of the computed paths, where the stretch is the ratio of the path length and the Euclidean distance covered. In the literature, many protocols have been evaluated via extensi ...
