- Fixed error when integrating a tool using a template of type 'Common'
- Improved clean up of RCE's temp directory
- General performance improvement in workflow data browser
- Fixed handling of scripts that were openend in an editor at the same time and that belong to different script components
- Optimizer component
- Improved behavior if optimizer fails or isn't available at all
- Script component
- Improved error handling if non-existing files are written to an output
- Fixed bug using boolean values in pre/post script
- Added support for relative paths to the tool directory (relative to the RCE installation directory)
- Fixed a bug where many crashed connections could cause a high number of remaining threads and could also cause a memory leak
- Added new command for batch execution. It executes a set of commands and shuts down RCE no matter what: --batch
- Added support for placeholder values on component instance base (and not only on component type base)
- Improved fault tolerance when execution a workflow in batch mode and not all of the required remote nodes exists immediately on start up because of network latency (but will be available directly after start up)
- Improved documentation of string security filter
- Added documentation for placeholder value files used in headless mode
- Added a view to execute RCE console commands
- Added miscellaneous context menu entries for faster access to key features (such as integrating a new tool or creating the workflow examples project)
- Fixed short cut for renaming workflow nodes (it is just F2 now)
- Improved visibility of self-connections of components in the workflow editor
- Component names are shortened from the center if the entire name is too long to fit in the workflow node box
- Further improved the GUI's responsiveness, especially when RCE is connected to remote instances
- Placeholders (such as Python installation path, cluster component credentials) are not shared between copied workflow files anymore
- Various bug fixes
- Cluster component
- Absolute paths to the cluster queuing system commands are now configurable
- Added support for indicating failed cluster jobs
- Converger component
- The number of iterations to consider in the convergence check is now configurable (not only the current and previous, but the current and n previous values can be considered now)
- Optimizer component
- Starts dispatching initial design variable values for evaluation not before it gets the first explicit evaluation request from the optimization algorithm
- Tools can be published and unpublished on the file-system level without restarting RCE (especially useful for non-GUI server nodes)
- Miscellaneous improvements
- The "wf run" command can now be used to run workflow files containing placeholders (Python path etc.) as well; this is done by specifying a JSON file containing the required placeholder values
- Added the "wf verify" command for batch testing of workflow files; placeholder files are supported as with the "wf run" command
- When installing RCE as a Linux daemon, the RCE instance can now be run as a non-root user (which is highly recommended); note that the installation process still requires root permissions
- Added a startup check to detect missing temporary folder permissions early
- Active connection attempts can now be cancelled by pressing "stop/disconnect" in the Network View, or by using the "cn stop" console command
- Failed connections waiting to auto-reconnect can now be made to reconnect immediately (without stopping them first) by pressing "start/connect" in the Network View, or by using the "cn stop" console command
- In addition to the remote execution of single tools, complete workflows can now be invoked through the SSH/SCP interface
- Added contextual help for all workflow components
- Removed the standard Eclipse platform's help content from the integrated help center and replaced it with information about RCE's user guide
- Extended the user guide with help for integrating tools in RCE
- Some fixes regarding the optimizer component
- Minor fixes
- Some fixes regarding the deletion of workflows
- Some fixes regarding connections (auto-connect, copy&paste, ...)
- Provided dynamic help in script component again
- Added an "Output Writer" component to write directories and files to the local file system
- Optimizer
- The iteration count is now available as an output
- Added support for the Vector data type (to support multiple (hundreds) of design variables)
- Added support for start values and optimal solution outputs
- Gradients variables can be set as goals in Dakota
- Added support for nested loops
- Script
- Added support for Vector and Matrix data types
- Added support for history data (shown in the workflow data browser)
- Fixed memory leaks related to frequent script execution
- Tool integration
- Added support for history data (shown in the workflow data browser)
- Added support for hot deployment of configuration.json files (i.e., if a new tool configuration is dropped at the proper place, the tool will be considered and integrated immediately without any further user interaction. Especially useful for RCE server instances without a GUI)
- Bugfix: All console output is now properly separated in the workflow console view
- Renamed component: Merger -> Joiner
- Replaced/improved some component icons
- Simplified the identifiers of components (the ones which are used in the .json files to configure which of the components are published)
- Improved the ToolAccess interface that allows external (non-RCE) clients to execute integrated tools via SSH/SCP
- Various bugfixes and performance improvements
- Improved the responsivness of the graphical user interface, especially in distributed setups under high load
- Workflow editor
- Connections are now properly handled when workflow nodes are copied and pasted
- Introduced different sizes and shapes for workflow components in the editor
- Removed the "Advanced" configuration tab as it is not intended (and therefore confusing) for end users Added support for a "point&click" method to connect component's endpoints (in addition to the existing "drag&drop" method)
- Workflow data browser
- The storage location of history data is now visible in the browser
- Component history entries now use the component's icon for easier recognition
- Sorting is now context sensitive (e.g., no support for alphabetical sortinng in timeline subtree)
- When exporting, all history data is now properly fetched recursively, even if it was not made visible before
- Updated the internal history data format for better long-term stability
- Improved the iteration counter for components in the workflow execution view
- Various graphical user interface improvements
- Added information about supported operating systems
- Added information about the scheduling parameters: required, initial, optional
- Added documentation of the ToolAccess feature
- General improvements
- Switched to Java 7 (i.e., Java 7 or higher is required to execute RCE 5.0.0 and above)
- Added a separate log file that only lists warnings and errors (warnings.log)
- The location of the instance data directory (including the data management's storage) can now be freely configured; it is no longer restricted to be inside "/.rce"
