This repository contains a SimPy behavioral model of the nanoPU P4 L-NIC architecture.
$ ./main.py --config config.json
The simulation parameters are in config.json. Here is an example:
{
"out_dir": "out",
"transport_protocol": "ndp",
"num_messages": 1,
"message_size": "fixed",
"message_size_value": 10,
"rtt_pkts": 10,
"data_pkt_trim_prob": [0],
"max_pkt_len": 100,
"min_message_size": 10,
"max_message_size": 10000,
"rx_link_rate": 100,
"tx_link_rate": 100,
"reassemble_max_messages": 100,
"packetize_max_messages": 100,
"sample_period": 500,
"timeout_ns": 10000,
"max_num_timeouts": 5,
"cpu_tx_rate": 100,
"ctrl_pkt_delay": "fixed",
"ctrl_pkt_delay_value": 1000,
"data_pkt_delay": "fixed",
"data_pkt_delay_value": 1000
}
At least one parameter value must be a list. Using the above configuration
file will result in 3 simulation runs. Each run will use a different value
for the "data_pkt_trim_prob" parameter. run-0, run-1, and run-2 will
use "data_pkt_trim_prob" = 0, 0.2, and 0.4, respectively. Any simulation
logs will be written to directory out/.
The architecture implementation is in ./nanoPU_sim.py.
