TAGGED: discovery-live, graphics
February 21, 2018 at 2:33 amapoerschkeSubscriber
I am running Discovery Live on a machine with two Keplar GTX Titan GPUs with 6 GB memory each. The simulations I am running are internal flow fluids. Whenever I have the fidelity slider maxed out the GPUs report 1440 and 1300 MB memory usage and 80% and 12% load respectively. I have tried running models with a SLI bridge, and no SLI bridge with similar results. The slots are both PCIe 3.0 x16. Drivers are the latest available.
When I run the same models on a machine with a single lower power GTX 1060 with 6GB, I see memory usage approaching 5 GB, and close to maxed out load.
Is there a software reason I am not able to utilize the resources of dual GPUs? Does the addition of an SLI bridge make any difference for Live? Is this likely an issue with the specific configuration of my computer?

I'll have to consult with the development team to see if this configuration is supported. I'll post another reply once I have some feedback.

Use of dual GPUs is not supported at the current point in time. We may add support for this in a future release.

I have a related issue.
I have a Quadro K6000 and a GTX 660.
How do I make Ansys Discovery Live use the Quadro K6000 as the GPU that computes the solution rather than the GTX660?
