2002 journal article

A hybrid MPI-OpenMP implementation of an implicit finite-element code on parallel architectures

INTERNATIONAL JOURNAL OF HIGH PERFORMANCE COMPUTING APPLICATIONS, 16(4), 371–393.

By: G. Mahinthakumar n & F. Saied*

Contributors: G. Mahinthakumar n & F. Saied*

topics (OpenAlex): Parallel Computing and Optimization Techniques; Distributed and Parallel Computing Systems; Advanced Data Storage Technologies
TL;DR: A hybrid implementation adapted for an implicit finite-element code developed for groundwater transport simulations is presented, finding that while the hybrid model is a promising approach for SMP cluster architectures, the payoff may not be justified for converting all existing MPI codes to hybrid codes.
