Pull Request resolved: #2556

Pull Request resolved: #2538

Fully reshardable ZCH:  we can handle any value which is in common with default value (768); this allows training or inference world size to be any factor of `total_num_buckets` (ie. 1,2,4,8,16,24,32,48,64,96,128, etc) and still have identical numerics.
