Scaling Collaborative Filtering with PETSc

2018 IEEE International Conference on Big Data (Big Data), 2018
Machine learning and recommendation systems have become extremely popular and widely used in recent years, with several major companies using recommenders to help their users sort through the vast array of products offered. Naturally, we want these recommender systems to give accurate predictions of products a user might like, but we also want these ...

Preliminary Implementation of PETSc Using GPUs

2013
PETSc is a scalable solver library for the solution of algebraic equations arising from the discretization of partial differential equations and related problems. PETSc is organized as a class library with classes for vectors, matrices, Krylov methods, preconditioners, nonlinear solvers, and differential equation integrators.

Abstract numbers and algebra in PETSc

2020
<p><span>Scientific computing related to solving partial differential equations (PDEs) frequently employ both real and complex numbers, consequently computation libraries such as PETSc provide support for these number types and their associated algebra.

Insertion of PETSc in the OpenFOAM Framework

ACM Transactions on Modeling and Performance Evaluation of Computing Systems, 2017
OpenFOAM is a widely used open source framework for simulation in several areas of computational fluid dynamics and engineering. As a partial differential equation (PDE)-based framework, OpenFOAM suffers from a performance bottleneck in solving large-scale sparse linear systems of equations.

Solving PDEs using PETSc in NetSolve

2005
A new way of combine the widely used PETSc math library and NetSolve (gird computing middleware) is explored in this paper. Using PDF file of NetSolve, applications using PETSc libraries can be called by NetSolve. However, the disadvantage of NetSolve Server causes the MPI’s programs can not make good use of the Server’s resource, which will lead to ...

Preconditioned Eigensolver LOBPCG in hypre and PETSc

2007
We present preliminary results of an ongoing project to develop codes of the Locally Optimal Block Preconditioned Conjugate Gradient (LOBPCG) method for symmetric eigenvalue problems for hypre and PETSc software packages. hypre and PETSc provide high quality domain decomposition and multigrid preconditioning for parallel computers.
