A Hybrid MPI+Threads Approach to Particle Group Finding Using Union-Find
James S. Willis, Matthieu Schaller, Pedro Gonnet +1
The Friends-of-Friends (FoF) algorithm is a standard technique used in cosmological -body simulations to identify structures. Its goal is to find clusters of particles (called g…
IndyLSTMs: Independently Recurrent LSTMs
Pedro Gonnet, Thomas Deselaers
We introduce Independently Recurrent Long Short-term Memory cells: IndyLSTMs. These differ from regular LSTM cells in that the recurrent weights are not modeled as a full matrix, b…
Fast Multi-language LSTM-based Online Handwriting Recognition
Victor Carbune, Pedro Gonnet, Thomas Deselaers +7
We describe an online handwriting system that is able to support 102 languages using a deep neural network architecture. This new system has completely replaced our previous Segmen…
Planetary Giant Impacts: Convergence of High-Resolution Simulations using Efficient Spherical Initial Conditions and SWIFT
J. A. Kegerreis, V. R. Eke, P. G. Gonnet +4
We perform simulations of giant impacts onto the young Uranus using smoothed particle hydrodynamics (SPH) with over 100 million particles. This 100--1000 improvement in par…
