New version of SpeedIT contains a new set of preconditioners:
- Algebraic Multigrid with Smoothed Aggregation (AMG)
- Approximate Inverse (AINV)
Now, your OpenFOAM simulations on GPU can be up to 3.5x faster compared to DIC/DILU preconditioners on CPU.
See our blog entry for more details on the performance.
SpeedIT provides a set of accelerated solvers for sparse linear systems of equations. Acceleration is achieved with a single reasonably priced NVIDIA Graphics Processing Unit (GPU) that supports CUDA. SpeedIT Plugin to OpenFOAM allows for running OpenFOAM simulations on GPUs.
