# Read network performance
# Input: net_report.out
# Output: network throughput and latency;
# Description:
	# This program calculates the network throughput and latency, from `net_report.out` file,
	# which is generated under multi2sim directory after running the shell script in 
	# the run_simulation_files directory.
