Certain constraints apply when using GPU (Graphics Processing Unit) technology within Autodesk Moldflow software.
- Analysis types
- Use of GPU technology is limited to certain types of analyses. At present, only 3D Fill+Pack analyses support GPU technology.
- Maximum model size
- The analysis you run is restricted by the size of the available memory on the GPU. For example, if your GPU card memory size is not large enough to run the full model, then the analysis will use the GPU for smaller time steps when the model is partially filled.
- Computer stops responding
- When running computation-intensive tasks on a GPU card, the card will be diverted from other tasks such as redrawing the Windows desktop or refreshing other applications. This can be especially noticeable when running multiple jobs simultaneously or when running a very large analysis.
CAUTION:
In extreme circumstances, Microsoft Windows may determine that the card has reached a locked up state and trigger a reset of the graphics drivers. If this happens, it is possible that the system will stop responding. Details on this behavior are available from Microsoft
here.
- GPU card drivers
- Ensure that you are using the latest driver for any installed card. You may need to download and install the latest driver manually.
Note: The automatic Windows Update function may not install the most recent version of the driver.
