Questions and Answers

What is the primary reason why applications with long execution times are a concern in supercomputing?

They violate supercomputer usage policies

They waste computing resources

They increase the risk of hardware or software failure (correct)

They cannot utilize checkpointing

What is the primary purpose of checkpointing in supercomputing?

To improve load-balancing decisions

To aid in performance monitoring and analysis

To provide snapshots of the application at different simulation epochs

To mitigate the risk of execution failure and associated losses (correct)

What is a characteristic of checkpoint files?

They are exclusively used in system-level approaches

They are typically small in size

They can be extremely large (correct)

They are used for debugging purposes only
