There is a way to mount a tar archive to a specific directory in a similar way you would mount an ISO image. You can use this command to //mount// (read-only) ARCHIVE (possibly compressed) to DIRECTORY:
  
   /opt/bin/tarmount ARCHIVE DIRECTORY   /opt/bin/tarmount ARCHIVE DIRECTORY
Line 107: Line 107:
  
   /opt/bin/tarmount -u DIRECTORY   /opt/bin/tarmount -u DIRECTORY
 +
 +If you mount your data in this way, there is only one //open// operation instead of thousands or millions of such operations when opening each file separately. This will positively affect runtime when your data is stored on the LUSTRE filesystem.
