Functions/Subroutines | |
| subroutine | s_initialize_mpi_proxy_module () |
| Initialize the MPI proxy module. | |
| subroutine | s_initialize_particles_mpi (lag_num_ts) |
| impure subroutine | s_mpi_bcast_user_inputs () |
| Since only the processor with rank 0 reads and verifies the consistency of user inputs, these are initially not available to the other processors. Then, the purpose of this subroutine is to distribute the user inputs to the remaining processors in the communicator. | |
| impure subroutine | s_add_particles_to_transfer_list (nbub, pos, posprev) |
| Adds particles to the transfer list for the MPI communication. | |
| impure subroutine | s_mpi_sendrecv_particles (bub_r0, rmax_stats, rmin_stats, gas_mg, gas_betat, gas_betac, bub_dphidt, lag_id, gas_p, gas_mv, rad, rvel, pos, posprev, vel, scoord, drad, drvel, dgasp, dgasmv, dpos, dvel, lag_num_ts, nbubs, dest) |
| Perform the MPI communication for lagrangian particles/bubbles. | |
| integer function | neighbor_tag (i, j, k) |
| Return a unique tag for each neighbor based on its position relative to the current process. | |
| subroutine | s_wrap_particle_positions (pos, posprev, nbubs, dest) |
| impure subroutine | s_mpi_send_random_number (phi_rn, num_freq) |
| Broadcast random phase numbers from rank 0 to all MPI processes. | |
| subroutine | s_finalize_mpi_proxy_module () |
| Finalize the MPI proxy module. | |
