Initialization and Finalization

Initialization and Finalization

Section titled “Initialization and Finalization”

This page describes the initialization and finalization procedures in Tolosa-lib applications.

Initialization

Section titled “Initialization”

Every Tolosa-lib application must initialize the library before use. This includes:

  • MPI initialization - Setting up parallel environment
  • Mesh loading - Reading mesh files and generating connectivity
  • Domain decomposition - Partitioning mesh for parallel computation
  • Timer setup - Initializing performance monitoring

Basic Initialization Example

Section titled “Basic Initialization Example”
program main
  use m_tolosa_lib
  implicit none


  ! Initialize MPI
  call MPI_Init(ierr)


  ! Initialize Tolosa-lib
  call tolosa_init()


  ! Load mesh
  call mesh_load('my_mesh.msh')


  ! Your simulation code here
  ! ...


  ! Finalize
  call tolosa_finalize()
  call MPI_Finalize(ierr)


end program main

Finalization

Section titled “Finalization”

Proper finalization ensures:

  • All output files are closed correctly
  • Memory is deallocated
  • MPI communicators are freed
  • Performance statistics are written

Finalization Steps

Section titled “Finalization Steps”
  1. Close all output files
  2. Deallocate mesh structures
  3. Print timing reports
  4. Finalize MPI
