Referring to multi gpu workflows, if I have 2 GPUs available and can run a 30q GHZ circuit on a single GPU, will the second GPU be automatically picked up for a 31q simulation on a jupyter notebook run?

I want to try avoid running mpirun on the command line for .py files and would like to run multi-gpu workflows on .ipynb files.

Thanks.

Congrats on the progress thus far.

Hey @Zohim_Chandani1!

You need to specify the number of processors via mpirun -np <number of processors>. mpirun is the only way — this isn’t going to be compatible with notebooks.
