GPU running simultaneously

[qinfa luo]

Hello, I would like to ask you some questions. If my computer has two 4080 Super graphics cards: 1. When I run Mumax code, can I specify one of the graphics cards to use? Or is it possible to have both graphics cards run simultaneously? 2. If specifying is possible, can I run two instances of Mumax code simultaneously and have them each utilize a different graphics card? If so, how can this be configured? 3. If I cannot specify the graphics card, will running a single Mumax code make both graphics cards work at the same time?

thank you

Hi,

If you specify multiple input scripts in the mumax3 command, like

mumax3 input1.mx3 input2.mx3 ... inputN.mx3

then mumax3 will distribute those N input scripts over all available graphics cards on the system.

This creates a queue which you can view on localhost:35367.

Best regards,

Jonathan
