Function Documentation

make_root_dir_path()

std::string metall::utility::mpi_datastore::make_root_dir_path ( const std::string &  root_dir_prefix )

inline

Parameters

root_dir_prefix

A prefix of a root directory path.

Returns

A path of a root directory.

make_local_dir_path()

std::string metall::utility::mpi_datastore::make_local_dir_path ( const std::string &  root_dir_prefix, const int  rank  )

inline

Makes the data store path of a MPI rank.

Parameters

root_dir_prefix	A prefix of a root directory path.
rank	A MPI rank.

Returns

A path to a local data store directory. The path can be passed to, for example, metall::manager to perform operations.
