Release Notes


  • Added a "structured copy" option that preserves the structure of the directory tree containing the files to be copied.
  • Added a "Connect to Prod Host" menu item to the "Connect" menu to conveniently connect to clusters and specific login nodes.
  • Introduced a new, minimal transfer status display to the bottom of the directory windows. Now one can see at a glance how many active, failed, and successful jobs have been launched.
  • When run on LC production hosts, Hopper now automatically adopts your other jobs running in the same LC zone (CZ, RZ, SCF). This job information is available both in the minimal and the full transfer status displays.
  • Directory window operations are now concurrent. Operations that previously tied up the entire user interface now tie up just a single directory window.
  • Significantly enhanced the file transfer choice algorithm, which reduces the number of two-hop transfers when working with multiple zones and/or multiple users.
  • Made detailed file transfer window more memory efficient.
  • Decreased memory footprint of "Show Clipboard" dialog.
  • Decreased memory footprint of audit dialog.
  • New automatic directory refresh capability.
  • Added a ping of prospective Hopper server hosts for availability before attempting to connect.
  • Can now make HSI connections to LANL and Sandia HPSS storage systems ( and on the SCF.
  • Modified server timeout behavior so that an attached client does not prevent server termination after a prescribed amount of server inactivity.
  • Fixed issue preventing TAR file updates from completing successfully.
  • Chopper: added aggregated copy and multi-volume copy commands.
  • Added ability to filter file transfer logs in order to view error messages only.
  • Fixed issue preventing NFT file transfers from being aborted properly.

  • Significantly enhanced support for Enclave (multi-zone and multi-user) operations.
  • Improved speed of status database when operating on large number of files.
  • Added more per-user disk usage views. View usage by directory, by users, or for a specific user per directory.
  • Added ability to convert format of text files.

  • Removed retired hosts and added new hosts to site file.
  • Added Multi-Volume Archive help information.
  • Fix for error that occurs when transferring files to/from some non-LC FTP servers.
  • Added workarounds to the file transfer logic in order to accommodate an FTP client that hardwires user names when connecting to storage.
  • Fixed problems with file transfer logic that occurred when initiating transfers from the EN between CZ and RZ/IZ.
  • Fixed race conditions between threads that could occur when parsing directory list output.
  • Can now handle an unexpected date/time format in the directory listing returned by a Windows-based FTP server.
  • Fixed an array-out-of-bounds exception caused by an update to the directory window in detailed view made by a thread other than the event-dispatch thread.
  • Improved management of jobs in order to correctly handle multiple user names per user.


  • Added multi-volume archive operation; a convenient way to transfer large directories to storage.
  • Better usage of existing host connections. Previously, Hopper required separate connections for the directory window and for each simultaneous transfer involving that host. Now, a single connection can be used for both a directory window and a single transfer as long as they don't both need to use the connection simultaneously. This can result in fewer password prompts and better interactivity.
  • Many usability improvements related to HPC Enclave, including fewer (and better defined) password prompts, particularly when connecting to RZFIS and RZstage from desktop machines.
  • Transfers with HSI now make use of HSI's multi-file parallelism.
