Agglomeration
- [Olivia] In the first two stages of a parallel design process we partitioned a problem into a set of separate tasks and then establish communication to provide those tasks with the data they needed. We looked at different ways to decompose the problem and focused on defining as many small tasks as possible. That approach helped us consider a wide range of opportunities for parallel execution. However, the solution that created is not very efficient, especially if there are way more tasks than there are processors on the target computer. - Now it's time to turn our thinking from abstract to something concrete and modify that design to execute more efficiently on a specific computer. In the third agglomeration stage, we'll revisit the decisions we made during the partitioning and communication stages to consider changes to make our program more efficient. Combining some of those tasks and possibly replicating data or…
