Hello! I have a slight problem, i need to combine an existing package MPI with DEAL.II encapsulated, and use MPI for both.
The issue is as follows, the tutorials for learning MPI is very transparent and intuitive that the basic calls is trivial if you have programmed with lets say MUTEX, the issue is actually how to combine the packages. What is the procedure to combine the MPI packages, any suggestions, anyone got good code examples, so i could extract the basic underlying ideas. I am not completely fumbling in the dark, i do know to write a MPI package, but i am very unsure about the topology issue, dont know which procedure is the most appropirate. I have three options - inter-communicators ( messy and i think it is totally overdo the thing ) - split communicators ( i dont think i gain mush since i have a sequential solver, each package use MPI solver ) - sharing same communicator ( tried but failed in the running i get memory error ) I sincerly appricate some advice on this matter.
