# Name of the file used to synchronize the start of benchmarks.
# When a node is connected to all other nodes, it creates this file.
# Ansible waits until all nodes have created the file and then deletes all of them,
# Which serves as a signal to all the nodes to start benchmarking.

# to deliver all submitted transactions.

# Maximal time to wait for the appearance of a sync file on a remote machine
# This needs to be at least the duration of a single experiment.

# Name of the directory in which to store the raw output of the benchmark.
# These the content of this directory will then be aggregated and written to {{ bench_result_file }}

# Name of the file to which the node's logging output will be written.
# by redirecting the node's stdout and stderr outputs to this file.

# JSON file to which the banchmark is expected to write its output.
# This file will be downloaded to the local machine once the benchmark is finished.
