Simple Distribution Computation via TCP

---

To accelerate the training speed on rcssserver3d, we set up a simple distribution computation platform. In order to deploy your tasks, you just need to do as follows:

Set up Servant Computation Node

1. create an account called optimization on each servant computer
2. open ssh port, add leader computer's public key to ~/.ssh/authorized_keys
3. set up the environment that your task need

Edit the Configuration Files

1. edit manifest.py

_host_port = {
    # here we set the hosts name, hosts IP, hosts TCP port
    'your_host_name': ('123.123.123.123', 2333),
    'your_host_name2': ('123.123.123.124', 2333),
    ......
}

There may be other options that you need to reedit in your task 2. edit hosts.conf, add your servant hosts into HOSTS and set your total number of your hosts

3. edit server.py, alter the eva function that you need to solve

4. edit clean.sh, set up your cleaning rules. Be carefull to deal with your important files.

Deploy Tasks into Sercant Nodes via Shell Scripts

./cmd_push.sh setup *ip or hostname* # set up one node
./cmd_push.sh setup-all # set up all nodes
``
#### Kick off Tasks
1. first start servant nodes by `./cmd_push.sh start`
2. run `python3 cma_es_dc.py`

#### Check the State of Servant Nodes
- simply you can use `./cmd_push.sh inspect` to check whether errors or exceptions occurred during server running. Also you can change the error catching key word in `cmd_push.sh`
- Sometime you may need to check the exact running state on servant node, you can just use
    - `./cmd_push.sh open *ip addr*` to open one terminal for servant node
    - `./cmd_push.sh open-all` to open terminals for all servant nodes
```bash
./cmd_push.sh start

#### File Interaction
- To get file from servant nodes
    - execute `./file_push.sh fetch *filename*` to fetch files renamed with prefix of their IP, an example may be as follows
    ```
    192.168.1.114-walkout  192.168.1.142-walkout  192.168.1.177-walkout
    192.168.1.137-walkout  192.168.1.145-walkout
    ```
- To push files from local to all servant nodes
    `./file_push.sh *filename*`

#### Clean Mess
execute `./cmd_push.sh clean` to clean all messes your task created, clean rules can be altered by editing the `clean.sh` file

#### Result Plot
- You can plot the result by `python3 result_plot.py`

python3 cma_es_dc.py # You'd better run this command in other terminal
