Implementation of MPI

Ertan Karaismail

Hi all, I am working on a 3D FVM based CFD code. It is runnning on a staggered grid, and I need to parallelize this code. I have some experience with PVM, but this time I have to use MPI. With PVM, we used to use a master code to spawn slaves and then each slave was running the same code with different grid info. To be more clear, slaves had the sequential code, which we were using for serial runs, plus some extra PVM commands for information exchange. On the whole, slaves were communicating with their neigbours as well as with the master at used defined time steps. This actually is a classical approach.

My question is if I can use the same strategy (Master/Slave) with MPI? I also have a Poisson solver parallelized with MPI. But I could not see any slave spawning and running the same code on slave. Anyway, I am a little confused.

I appreciate any comment, refererence or small examples that you can tell me.

Thanks
