Retools is a set of modifications to the commonly used open source utilities bzip2, gzip, rsync, and tar that automatically selects the Lustre stripe count for created and/or extracted files according to the sizes of the files involved. By striping large files over a higher number of physical disks and small files over a lower number, aggregate I/O bandwidth for large files is maximized and the impact to the file system due to small files is minimized.
