MPI-FTW is a software for MPI-based directory tree traversal. It allows users to easily traverse large directories and manage data using MPI technology.
MPI-FTW is a powerful application designed to traverse a directory tree using MPI. Its main function is to allocate a process to walk any newly discovered directory branch. Once the program has completed its task, it will provide users with detailed statistics including directory count, file count and the time it took to complete.
This program is also equipped with a special feature that allows users to run specific commands on every directory that is found. To initiate this, users can simply run the "mpi-ftw" command with its designated path and additional arguments.
For example, users can run the following command:
mpirun [mpi arguments] mpi-ftw --path=path [--cmdfile=filename] [--verbose]
In this command, "path" refers to the root directory where the program should start its directory tree traversal. Optional arguments such as "--verbose" can also be used to provide users with more information on traversal progress.
Users can also specify a file containing the commands to execute on directories using the "--cmdfile" argument. The file format for the commands is specified below:
# comment
all "command" or process_range "command1" and/or processes "command2"
A "#" character at the start of a line indicates a comment. Commands can be specified on a process-by-process basis, and processes 0 and 1 are reserved for management and collection purposes only.
Users can use the "all" option to specify all processes except for process 0 and 1. Alternatively, they can also use "process_range" to specify a range of processes to run a command on, or "processes" to specify a comma-delimited list of processes. In addition, ranges and comma-delimited lists can be included on the same line.
Example usage could be:
2-5,10-12,15 "echo directory = %D"
18,20,22,23-26 "ls -al"
all "ls %D"
Users can also use special conversion variables in their commands, which are:
%r - Rank of process
%R - Relative path designation
%P - Full parent directory path
%D - Full current directory path
%A - Last directory in path (final /dirname in current directory)
Overall, MPI-FTW is a valuable tool for any software developer who needs to work with directory trees using MPI. Its user-friendly design and powerful features make it an excellent choice for anyone looking for efficient and reliable directory traversing capabilities.
