The idea of this PR is to bypass the bottleneck of the mesh read in (reading and partitioning the mesh in serial).
A new LOGICAL control file keyword has been added:
read partitioning from fileswith the default value of.FALSE.. The keyword specifies if the solver should read the partitioning information from files instead of performing the mesh partitioning. When.FALSE., the solver reads the mesh file in serial at preprocessing, partitions the mesh, and writes the partitioning information to files in./MESH/partitioning_NUMRANKS_ranks(whereNUMRANKSis the number of ranks). When.TRUE., the solver will directly try to read the files in that folder. If the files do not exist, the solver will throw an error.
