Parallel Learning Example
=========================

Here is an example for LightGBM to perform distributed learning for 2 machines.

1. Edit [mlist.txt](./mlist.txt): write the ip of these 2 machines that you want to run application on.

   ```
   machine1_ip 12400
   machine2_ip 12400
   ```

2. Copy this folder and executable file to these 2 machines that you want to run application on.

3. Run command in this folder on both 2 machines:

   ```"./lightgbm" config=train.conf```

This distributed learning example is based on socket. LightGBM also supports distributed learning based on MPI.
