[Trilinos-Users] Rythmos package using MPI

[Coffey, Todd S]

  Hi Jatin.

  Rythmos uses an underlying linear algebra interface from Thyra which can be used in serial or parallel (typically by using an Epetra/Thyra adapter).  The application must choose how to distribute the vectors and matrices in parallel and then Rythmos simply operates on the vectors and matrices through algebraic operations and does not need to know anything about the parallel environment.

  All of the integration schemes in Rythmos will (should) operate correctly on a parallel distributed differential equation.

  Let me know if this answers your question.

Thanks!

Hi all,

I have a small question on the Rythmos package for integration of differential equations.

I have a reaction diffusion equation (basically PDE) which I solve in 3D using FEM and time integration schemes.

The time integration schemes implemented in rythmos, do they use parallelisation like MPI, and are the matrices distributed in parallel and solved simultaneously?

and if so, are they faster in computation using MPI ?

Thanks in advance for your help.

Jatin
