Create an experiment
Now that all the experiment material has been successfully uploaded on the airlock you will have to create a task file. The task file is a simple tar.gz archive file that contains your experiment material alongside an experiment description file:
The experiment description file
The experiment description file called
scenario.yaml will be looked for and read by the experiment scheduler to get which nodes and what software will be used during the experiment. It also gives the necessary startup scripts and parameters that the user provides for his experiment.
Here is a simple example of a
# Example scenario description file # # All lines starting with "#" and empy lines are ignored # Scenario textual description # simple string (a one liner) description: OFDM tx-rx example scenario for CorteXlab # Experiment maximum duration # Time after which the experiment is forced to stop # integer (seconds) duration: 120 # Node list # # format: # # nodes: # (machine): # command: (entry point script relative to the task root) nodes: node4: command: benchmark_rx.py --antenna="TX/RX" --rx-gain=25 -v -W 2M -f 2.49G node6: command: benchmark_tx.py --antenna="TX/RX" --tx-amplitude=0.2 -v -W 2M -f 2.49G
This file uses its own syntax and is self-documented. Adapt this example to suit your needs.
Creating the task file
scenario.yaml file is written, put all the experiment material and the
scenario.yaml file in the same directory. The file tree could look like something like that:
... ├── ofdm_txrx │ ├── benchmark_rx.py │ ├── benchmark_tx.py │ ├── receive_path.py │ ├── scenario.yaml │ ├── transmit_path.py │ └── uhd_interface.py ...
Now, use the Minus CLI to create the task file:
you@srvairlock:~$ minus task create path/to/the/folder
The success (or failure) of the creation will be printed on screen. The task file will be created at the same level and name than the targeted experiment folder but with a
