Workflow components
- 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
GUI
- 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
Documentation
- Added information about supported operating systems
- Added information about the scheduling parameters: required, initial, optional
- Added documentation of the ToolAccess feature
- General improvements
Configuration and administration
- 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"
