DP-GEN simplify
This article introduces how to perform DP-GEN simplify on the Bohrium platform.
Step 1: Turn on the node
Refer to the "DPGEN Tutorial" for how to turn on the node.
Step 2: Prepare input files
To use DP-GEN simplify, you need to prepare initial data, parameter files, and calculation files. Take perovskite as an example:

Step 3: Submit Job
Execute the following command in the /simplify_example directory:
nohup dpgen simplify simplify.json machine.json 1>log 2>err&
To monitor job status and obtain results, please refer to the DP-GEN documentation.
