is this model can use multi cpu for relaxing?

[sunjiwon]

when i use the this code, the cpu load is always equal when allocate 32 core and 1 core.
i think this code is run using in 1 core-cpu.

1. please let me know 'how to use multi-threading in your code'
2. is it faster using gpu in Relaxing code?

from m3gnet.models import Relaxer
relaxer = Relaxer()
relax_results = relaxer.relax(candidate_structure[0], verbose=True, steps=2000, interval=20, )

Thank you for creating such an amazing code.
