There was a problem hiding this comment.
Should there be a sample run with -init to illustrate the new feature?

This PR use the FOM solutions from first training parameter to initialize all FOM calculations of other parameters.
If
-initoption is used,Line 510-515: when
offline && id == 0, the computed FOM solution is saved.Line 464-488: when
offline && id > 0orfom(FOM reference solution calculation), the saved solution is loaded and used to initialize the LOBPCG solver.
