HPC Data Exchange Platform

This platform allows the read-only sharing of data produced on RRZE's HPC systems and located on /home/saturn, /home/titan, or /home/vault with (external) collaborators.

The HPC team of RRZE operates the infrastructure, however, all content is at the only responsibility of the individual HPC users.

The service is provided as-is on a best effort basis without further guarantees and may be stopped at any time at short notice. Therefore, do not publish the links directly but use some PID service (e.g. DOI) where you can change the target URL later on if needed.

HowTo

  1. Send the top level directory you would like to share to support-hpc@fau.de (e.g. /home/saturn/grp/usr/my-data/sharing/)
  2. All files to be shared must be readable for others; directories must be readable and executable for others. (e.g. chmod a+rX -R /home/saturn/grp/usr/my-data/sharing/)
  3. Only symbolic links for which the target file or directory is owned by the same user id as the link will be followed.
  4. All directories on the path to the sharing directory must be executable for others (but not necessarily readable). (e.g. chmod a+X /home/saturn/grp/usr/)
  5. The sharing directory must contain a .htaccess file which grants permissions (either to everyone or to specific users; see examples below)
    The default permissions are "deny" for security reasons, thus, without any .htaccess everyone will get 403 errors only.
  6. The sharing directory can be accessed as https://hpc-mover.rrze.uni-erlangen.de/HPC-Data/0x7b58aefb/some-hash-value/
  7. index.html files in the sharing directory will be ignored

Examples for .htaccess files

.htaccess file allowing access by everyone

AuthType None
Require all granted

.htaccess file allowing access to any specific users

AuthUserFile /home/saturn/grp/usr/.htpasswd
AuthName "SimData"
AuthType Basic
# allow any user from the .htpasswd file
Require valid-user

The .htpasswd file can be generated using htpasswd (e.g. on csnhr).

.htaccess file allowing access to specific user

AuthUserFile /home/saturn/grp/usr/.htpasswd
AuthName "SimData"
AuthType Basic
# only allow the two named users which must be listed in the .htpasswd file
Require user  max_mueller  franz_huber
