why GPU 0 is free?? and GPU 2 is working ?
Killing process 18757 ends up killing the zm process running on GPU 0 (being the process using it as reported by nivida-smi).
--dev option is using CUDA device ids that are not the same as the ones reported by nvidia-smi.
Hence, in your case:
* GPU 0 is CUDA dev 2.
* GPU 1 is CUDA dev 0.
* GPU 2 is CUDA dev 3.
* GPU 3 is CUDA dev 1.
