What is this new Multi-GPU Fluent Solver in 2022R1 update. How to actually use this feature?

[Rob]

You need an Enterprise level licence and then turn on beta features.

Is there any link to the documentation on Multi-GPU Fluent Solver in 2022R1.
Do we need to select Solver GPGPUs per Machine also?
Should I select GPU(Beta) for using the Multi-GPU Fluent Solver?

Check Beta Features Manual.

I have selected Capability Level Enterprise and show beta launcher options are on. I am getting the following message
"Enabling this option makes beta workspaces and Fluent Launcher beta options visible, but it does not enable beta features in the resulting Fluent session.
Do you want to proceed?"
Where can I find the Beta Features Manual? Any link?
What to do? I want to test the new multi GPU capability

You see the help button, click on it then a Browser will open navigate back to main Fluent help and select beta features manual.

I opened the fluent from the command prompt as mentioned in the Beta Features Document
I got this message on the console
*********************************************

For faster simulations, please start the application with the appropriate parallel options.

It says my simulation can be made much faster. How to set the appropriate parallel options to enable 4 way parallel execution?

An Academic licence isn't Enterprise. Turn off the gpu stuff and launch Fluent normally. Set solver processes as 4, that's as many as you have without buying HPC packs. If you have Student you have a maximum of 4 cores and 512k cells. Research level licences remove this limitation, but your University will be providing them on the campus system.
