Communication Cost in Distributed Systems
A significant challenge in distributed systems is the cost of communication. In a network of nodes, each node must exchange data with others in addition to performing local computations. This data exchange introduces overhead, and in large networks, the expense of distributing and collecting data can become so substantial that it offsets the time savings gained from parallelism, thereby limiting overall performance and scalability.

Numerical Computation Issues in Distributed Training
A research team is training a large model on 128 processing units, and the process takes 10 days. To accelerate the training, they double the number of processing units to 256. However, the new training time is 7 days, not the expected 5 days. Which of the following statements best analyzes this outcome?

A team is training a large computational model on a distributed system. They find that increasing the number of processing nodes from 8 to 16 nearly halves the training time. However, when they increase the nodes from 16 to 32, the training time decreases only slightly. What is the most likely explanation for this diminishing return on performance?
