Dear users of the Einstein Toolkit, I have a question: I would like to integrate the geodesic equations for a large quantity of particles in parallel (e.g. one million). To save computational time, I want to make sure that the arrays containing the particle data are handled by the same process that takes care of the corresponding grid patch on which the particles are moving and only communicate particle data if a particle moves to another grid patch.
Since I only want a process to communicate with the processes that contain the adjacent grid patches, can I access information on which process owns which grid patch and if yes, how? So far I have only found functions that return the upper and lower bounds for the local process, but each process would need to know where all the rest of the grid is. Kind regards, Cosima Breu _______________________________________________ Users mailing list [email protected] http://lists.einsteintoolkit.org/mailman/listinfo/users
