Fsstats (FileSystem Statistics) Data to Support and Enable Computer Science Research

To enable computer science research Los Alamos National Laboratory is releasing static file tree data (fsstats) for some of our parallel filesystems. These data include aggregate information on capacity, file and directory sizes, filename lengths, link counts, etc. The fsstats cover 9 anonymous parallel filesystems ranging from 16 TB to 439 TB total capacity used and file counts range from 2,024,729 to 43,605,555. The following sets of data are provided by Los Alamos National Laboratory under universal release to any computer science researcher to use to enable computer science work.

If you use these data in your research please recognize Los Alamos National Laboratory for providing these data.

README: For details on the results and what each field means, see the README. For additional questions, see the FAQ. For more information on the fsstats project in general, see the PDSI fsstats page.

Please download at least the README file using this webpage and enter your email address - we would like to know how many people are using these data to make sure these releases are worth our time, and we'd like to be able to followup with people who are using these data.

Details for the Machine System Number associated with the data may be found on the anonymous machine table page.


Update! The "directory size (entries)" histogram was incorrect - everything was always 1 entry. This is fixed for each filesystem and the rest of the file remains unchanged. Thanks to Yifan Wang and the CMU PDL team for finding and reporting this issue!
