Comment (by kelman):

 It's not well-documented, as I believe it's still considered experimental.
 You can enable it by configuring Ipopt with --enable-inexact-solver and
 setting the option inexact_algorithm to yes. It also requires you to build
 Ipopt with Pardiso, though I believe some of the other linear solvers
 might also be supported with the same algorithm.

 Don't be surprised if it doesn't work as well as you hope it might, I was
 disappointed with its performance on the optimization problems I was
 solving. It seems it only helps for some types of problem structures.
