Cuda IPC Could transfer between the devices which using CUDA_VISIBLE_DEVICES limited that are invisible to me?

processA set CUDA_VISIBLE_DEVICES=0, could it can use ipc transfer device 0 data to process B.
processB set CUDA_VISIBLE_DEVICES=1, could it get process A’s device 0 data through ipc function?

I don’t think so. Did you try it?
