Synchronization Costs in Distributed Systems
A significant issue in large-scale distributed systems is the additional cost introduced by node synchronization. It is common for some nodes to take longer to complete their computations, which forces faster nodes to wait. This idle time for the faster nodes, while waiting for the slowest ones to catch up, reduces the overall efficiency of the system.

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?

Performance Bottleneck in a Synchronous Distributed System
In a synchronous distributed system with four computational nodes, the time taken for each node to complete a single step is 100ms, 120ms, 150ms, and 110ms, respectively. All nodes must wait for the slowest node to finish before starting the next step. What is the total idle time accumulated across all nodes during this single step?
