Sorry for my belated response.
Question: what do rank and size of communicator mean?
The size member of the communicator object is the number of processes
you launched. For example,
When you do
$ mpirun -n 4 python ...Then, comm.size returns 4.
The rank of the communicator is the unique index assigned to each process.
I have tried to use CPU instead as my Graphics does not support Cuda
Currently, we do not support CPU version of a communicator, only one for CUDA device.
