MPI-FTW Description

MPI-FTW is an application used to traverse a directory tree using MPI. MPI-FTW is an application used to traverse a directory tree using MPI. Each time a new directory is located, a process is allocated to walk that particular branch. Upon completion, this program will provide directory count, file count and time to complete statistics.This program also accepts an argument that states that commands are to be run on each directory found.RUNNINGUsage: mpirun mpi-ftw --path=path Where path is a required argument that specifies the top level path to begin walk.--verbose is an optional argument that provides more information on traversal progress.--cmdfile specifies a file containing the commands to run on directories. The format of this file is specified below.The basic format is as follows: # comment all "command" or process_range "command1" and/or processes "command2"A line starting with # is a commentcommands can be specified on a process by process basis.NOTE: Processes 0 and 1 are reserved for management and collection purposes. Use processes >= 2"all" specifies all processes (with the exception of process 0 and 1)process_range is a range of processes to run command processes is a comma delimited list of processesprocesses ranges and comma delimited lists can be included on the same line #example 1: 2-5,10-12,15 "echo directory = %D" 18,20,22,23-26 "ls -al" #example 2: all "ls %D"Special conversion variables can be used in the command. The conversion variables are: %r rank of process %R relative path designation %P %D full current directory path %A last directory in path (final /dirname in current directory)
