DESCRIPTION:We review the techniques for solving the topological string fo
 cussing on the recent &nbsp\;progress in improving the high genus boundary
  conditions by considering the non-commutative resolutions of maximal unip
 otent monodromy points with Z2 torsion\, the knowledge of modular D4-D2-D0
  gauge theory indices and wall crossing formulas relating the latter to Do
 nalsdon-Thomas\, Pandharipande Thomas and finally Gopakunar Vafa invariant
 s. The obtained &nbsp\;high order perturbative results are used to confirm
  and extend analytic non-perturbative results based on resurgence techniqu
 es and in particular a transseries solution of the holomorphic anomaly equ
 ations.
