I know that "Solver::Options::num_threads" can compute jacobians by multi-threads very efficiently and it works pretty well in my program.But I found in my summay that now the residual computation time is dominant. I wonder if there is a way similar that can compute residuals by multi-threads too ?

Solver::Options::
num_threads
Default: 1
Number of threads used by Ceres to evaluate the Jacobian.
Thanks, Do you mean that it can also evaluate residuals? If thats the case, I would suggest make it clear on the API document too.
