The environmental impacts of scientific computing
Loïc Lannelongue, Anica Araneta · University of Cambridge
Mon, Oct 12 · 11:00 UTC · Online
Scientific computing has environmental impacts that extend beyond the growing use of artificial intelligence. This seminar examines how research computing affects the environment, how researchers can measure and reduce those effects, and how funders are responding. It also asks whether efficiency alone provides an adequate strategy. The speakers introduce Green DiSC, a certification scheme for sustainable computing, and the Environmentally Sustainable Computational Science community forum. The discussion connects practical choices in computational research with community approaches to sustainability and concludes with questions. It is suitable for researchers and software developers without prior knowledge of sustainable computing.

Asynchronous Methods on AMD GPU-Based Systems
Katarzyna Swirydowicz · Advanced Micro Devices (AMD)
Fri, May 8 · 13:00 UTC · In person
Katarzyna Swirydowicz uses an asynchronous solver on an AMD system to examine the practical implementation of computational linear algebra across CPUs and GPUs. The talk introduces the relevant computational ideas, programming models, and software tools, then considers how algorithmic structure interacts with hardware capabilities. This case study illustrates both the opportunities and implementation challenges of asynchronous methods for large-scale scientific computing on GPU-accelerated systems.
Bisected graph matching improves automated pairing of bilaterally homologous neurons from connectomes
Benjamin Pedigo
Wed, Sep 28, 2022
Graph matching algorithms attempt to find the best correspondence between the nodes of two networks. These techniques have been used to match individual neurons in nanoscale connectomes -- in particular, to find pairings of neurons across hemispheres. However, since graph matching techniques deal with two isolated networks, they have only utilized the ipsilateral (same hemisphere) subgraphs when performing the matching. Here, we present a modification to a state-of-the-art graph matching algorithm which allows it to solve what we call the bisected graph matching problem. This modification allows us to leverage the connections between the brain hemispheres when predicting neuron pairs. Via simulations and experiments on real connectome datasets, we show that this approach improves matching accuracy when sufficient edge correlation is present between the contralateral (between hemisphere) subgraphs. We also show how matching accuracy can be further improved by combining our approach with previously proposed extensions to graph matching, which utilize edge types and previously known neuron pairings. We expect that our proposed method will improve future endeavors to accurately match neurons across hemispheres in connectomes, and be useful in other applications where the bisected graph matching problem arises.

A More Efficient Sifting Lemma and a Stronger 3-Player Communication Lower Bound
Zander Kelley · Institute for Advanced Study
Tue, Apr 21 · 14:30 UTC · Hybrid
Zander Kelley presents joint work with Xin Lyu separating randomized and deterministic three-player communication in the number-on-forehead model. Earlier work by Kelley, Lovett and Meka gave an explicit function with an efficient randomized protocol but a deterministic lower bound of Ω(n^(1/3)). The argument studies whether its yes-instances can be covered efficiently by small cylinder intersections. A sifting lemma finds a denser induced subgraph inside a bipartite graph with large grid norm. An improved version raises the communication lower bound to Ω(n^(1/2)). The key structural result covers small cylinder intersections by a few reasonably small slice functions; the talk compares this simplification with Szemerédi’s triangle removal lemma.

Kevin Buzzard of Imperial College London joins Steven Strogatz to discuss Lean, formal proof assistants and the effort to encode mathematical knowledge in a computer-readable library. They explore how computers verify difficult arguments, the distinction between Lean and its mathematical library, the formalization of work by Peter Scholze and Dustin Clausen, and the prospects and limits of computers creating new mathematics.

Spectral Partitioning for Metrics (And NNs Too)
Alex Andoni · Columbia University
Thu, Nov 29, 2018 · 22:00 UTC
This talk establishes a general reduction from nonlinear spectral gaps of metric spaces to data-dependent space partitions in the form of locality-sensitive hashing. The reduction yields an approach to high-dimensional approximate near-neighbor search and a data structure for any d-dimensional norm whose query algorithm makes a sublinear number of probes. Its approximation factor is O(log d), improving on the square-root-of-d factor available from the generic approach based on John’s ellipsoid. The presentation connects spectral properties, geometric partitions, and efficient approximate search. Joint work with Assaf Naor, Aleksandar Nikolov, Ilya Razenshteyn, and Erik Waingarten.
Efficient Reductions for k-Nearest Neighbor Search
Rasmus Pagh · IT University of Copenhagen
Fri, Nov 30, 2018 · 00:00 UTC
Theory for high-dimensional nearest-neighbor search often assumes a known search radius, a specified approximation ratio, and a request for one nearby point. Practical applications instead ask for the exact k nearest points without knowing the relevant radius; an appropriate approximation parameter also depends on the data distribution. Existing reductions between these formulations introduce polylogarithmic time or space overhead that can make them unattractive in practice. This talk presents simple, more efficient reductions that solve k-nearest-neighbor search using locality-sensitive hashing and address this gap between theoretical guarantees and practical queries. Joint work with Tobias Christiani and Mikkel Thorup.
