How to use DistributedDataParallel() and init_process_group() in a HPC?

I will use HPC for my research and I don't know a lot about parallel or distributed computing.
I really don't understand the DistributedDataParallel()
in pytorch. Especially init_process_group()
.
What is the meaning of initializing processes group? and what is
init_method : URL specifying how to initialize the package.
for example (I found those in the documentation):'tcp://10.1.1.20:23456'
or 'file:///mnt/nfs/sharedfile'
What are those URLs?
What is the Rank of the current process?
Is world_size
the number of GPUs?
It would be really appreciated if someone explained to me what is and How to use DistributedDataParallel()
and init_process_group()
because I don't know parallel or distributed computing.
I will use things like Slurm(sbatch) in the HPC.
