Achieving Optimal HyperWorks Performance on Windows – Part 2 | Remote Execution
Altair EmployeeIn this article, I will discuss best practices for achieving optimal performance in HyperWorks and offer troubleshooting recommendations if you face any issues while loading or running HyperWorks remotely.
- Hardware Dimensioning
- Remote Access
- OpenGL requirements
- Windows 7 Remote Access
- Managing Low Performance
For additional best practices and troubleshooting recommendations for local execution see Achieving Optimal HyperWorks Performance on Windows – Part 1 | Local Execution.
Hardware Dimensioning
HyperWorks applications require graphic resources. Significant memory usage may be required when dealing with large models (over a million elements), therefore it is important that you dedicate a single physical node to a restricted number of users. A common recommendation is to dedicate one physical node to 2 to 4 users.
Also, make sure that you have:
- A stable and performant connection between the server and the clients.
- Updated graphic board drivers (based on OEM website) on both the server and the client computers. If you need to install a new driver, make sure to run a custom installation and to select the option Perform a clean installation which will remove any obsolete setting files.
Remote Access
Windows proposes that you use the Windows RDP inner tool for remote access. Note: Windows RDP should be automatically configured for Windows 10.
Nevertheless, make sure Enable Windows Services for RDP is hardware accelerated from the Local Group Policy Editor.
Please note that restarting the server is mandatory when changing a Group Policy.
OpenGL requirements
You need to make sure that OpenGL is active and that its version is higher than the default 1.1 from the Windows generic software OpenGL renderer.
You can verify OpenGL hardware rendering is being used with any third-party application (eg: OpenGL Extension Viewer) that checks the OpenGL remotely when you are logged in via RDP.
Windows 7 Remote Access Recommendations
If you are using Windows 7, please make sure to upgrade RDP to a version that supports OpenGL hardware acceleration:
Note: Windows 7 is no longer supported by Microsoft, and is therefore no longer supported by Altair.
Managing Low Performance
The features listed below are known for causing HyperWorks performance issues if your hardware settings don’t fulfill the minimal requirements. If the recommendations above do not work, please deactivate the options below via HyperWorks preferences:
Tip: You can use the search bar in the top, left of the Preferences dialog to quickly find preferences.
- Dynamic Center of Rotation
- Hover High-light
- Anti-aliasing
- Disable writing to the command file
