Dear OpenFOAM experts:

I ran interFoam on an AMD X2 3800+ CPU (3 GB DDR, total number of elements is about 390,000) using LAM (simple decompose). It actually took longer time to run when compared to running in serial. I noticed that it required more number of iterations to converge at each time step when running in parallel. Also, extra communication is needed in parallel. Is there any way to improve the performance in parallel?

I am setting up a cluter with 6 workstations (each with either dual CPUs or a dual core CPU). Gigabit switch is used to connect the 6 boxes. Most of my work used interFoam/lesInterFoam. Now, I am wondering whether it is worth it to even setting up the cluster (most of the cases are less than 1 million elements).

It will be appreciated if someone can shed some light on this?
