Representing Fluid Dynamics as a Rigid-Body Dynamics Problem with Friction and Contact
The purpose of this project is to understand whether fluid motion can be accurately represented as a very large collection of rigid spheres. The motion of fluids is traditionally modeled using the Navier-Stokes equations, whereas …
Distributed-Memory Granular Simulation
Granular material on nearly any practical scale involves computing the dynamics of billions of bodies. In order to generate high-resolution predictions for the behavior of granular material, a simulation must track each of the multiple …
SPIKE GPU – An Implementation of a Recursive Divide-And-Conquer Parallel Strategy for Solving Large Systems of Linear Equations
This project proposes to investigate, produce, and maintain a methodology and its software implementation that leverage emerging heterogeneous hardware architectures to solve billion-unknowns linear systems in a robust, scalable, and efficient fashion. The two classes …
SBEL student Conlain Kelly wins prestigious scholarship
This month, SBEL undergraduate Conlain Kelly won a scholarship from the prestigious Astronaut Foundation Scholarship for the 2018-19 school year. The award includes up to $10,000 and an expenses paid trip to the ASF Innovators Gala August 23-25, …
SBEL students land summer internships
Congratulations to the SBEL members who have gotten internships for this summer! For our undergraduate students, Dylan Hatch will be interning at the prestigious Qualcomm Linux Kernel Team, and Conlain Kelly is joining Product Development at Ford Motor Company …
Coupled Fluid-Flexible Body Investigation Using Chrono::Fluid
The interaction of fluid-flexible bodies was studied via a Lagrangian-Lagrangian framework, relying on Smoothed Particle Hydrodynamics, a general 3D rigid body dynamics, and an Absolute Nodal Coordinate Formulation (ANCF). The dynamics of the two phases, …
Characterization of Xeon Phi with Linear Algebra Workloads
The efforts behind this independent study are to analyze how well suited Xeon Phi is for some frequently used linear algebra routines such as factorization and solvers. We are working with Intel MKL 11.1 on …
Performance Analysis of CULA on different NVIDIA GPU Architectures
The CULA is a next generation linear algebra package that uses the GPU as a co-processor to achieve speedups over existing linear algebra packages. CULA supports matrix inversion operation which helps in solving and factorizing …
Performance Comparison Study between NVIDIA Fermi and Kepler Architecture
A comparative study between Nvidia Fermi and Kepler architectures are being undertaken. The key aspects being targeted are performance scaling for computational kernels like tiled matrix multiplication, memory transfer behavior, gains using streaming and performance …
