Checkpoint Save Time

Problem

Estimate the time in seconds to write a checkpoint: checkpoint_bytes / (write_bandwidth_gbps * 1e9).

The signature is checkpoint_save_time_s(checkpoint_bytes, write_bandwidth_gbps). Return seconds as a float.

Hint

One gigabyte per second writes 1e9 bytes per second.
