Inquiry About Parallel Computing

[lidafa0206]

Thanks for the great package!

I hope this message finds you well. I have a question regarding parallel computing. When I run the command mpiexec -np 4 xxx.py, I notice that I receive four separate results. Does this imply that MPI is executing four independent calculations on the model simultaneously, rather than enhancing the computation speed by a factor of four?

Given that my program involves high-dimensional parameters and tends to run slowly, I would greatly appreciate any advice on methods to accelerate its execution.

Thank you very much for your time and assistance.
