# k-nodes runs a Codex network with k nodes in which a file is uploaded to

# node zero and then the remainder k - 1 nodes download it concurrently.

# Outputs download times to a log file.

# Usage: k-node.sh <node_count> <repetitions> <output_log> <file_sizes...>

# Example: k-node.sh 5 10 ./k-node-5-10.csv 100 200 500
