This table view above allows you to see the detailed statistics of all communication ops in each node. This allows you to see what operation types are being called, how many times each op is called, what is the size of the data being transferred by each op, etc. 
Memory View:
This memory view tool helps you understand the hardware resource consumption of the operators in your model. Understanding the time and memory consumption on the operator-level allows you to resolve performance bottlenecks and in turn, allow your model to execute faster. Given limited GPU memory size, optimizing the memory usage can: 

Allow bigger model which can potentially generalize better on end level tasks.
Allow bigger batch size. Bigger batch sizes increase the training speed.
