Could you please briefly explain how the parallelization in AMG would work? and what challenges we might face? and/or how to solve them? I won't understand that right now, but in future I'll come...

In implicit solvers, the solution depends on the next timestep, and it won't be possible to solve the set of linear equations, if even a single equation was missing. So we can't...

Basically what I'm thinking ... 1. fork once 2. do work on each partition completely separately on each core (other than sharing boundary data), 3. join back at the end of the simulation Ex...

When the problem size becomes too large, we need to distribute the data to multiple cores. For explicit codes, it's easy to just partition the grid, and distribute every one of...

Hi everyone, hope you had a great start to this new year, I'm trying to understand how can we actually develop for scaling our code to large problem sizes (example : ~100 Million cells, for LES...
