Accelerate OpenFOAM with SpeedIT 2.1

May 24th, 2012

SpeedIT provides a set of accelerated solvers for sparse linear systems of equations. The library supports C/C++ and Fortran, and it can be used with OpenFOAM to accelerate CFD simulations. SpeedIT 2.1 contains two new preconditioners:

• Algebraic Multigrid with Smoothed Aggregation (AMG)
• Approximate Inverse (AINV)

OpenFOAM simulations on the GPU can be up to 3.5x faster compared to CG and DIC/DILU preconditioners on the CPU and up to 1.6x faster if you run GAMG.

See the SpeedIT website and blog for more details.

    Thank you for the publication of the code, and I want to use it as a performance basis for comparison.
