Parallelizing on multiple GPU
I have access to an 8 GPU cluster for running my model. Is there a flag I can set in my .yaml file that I use to launch the job to have the model take advantage of more than one GPU? Right now, the only flag I have is --backend cudaC in the BMv4_simulation command.
Additionally, even when I launch the model on a single GPU, it is only hitting 70% utilization and using roughly 9GB of vRAM, but i have 96GB available. Any suggestions on how to use the hardware I have more efficiently and hopefully speed up my model a bit? Are there any settings I can set in the simulation.json?
Thanks for any help!
