The thing with multicore computing is that you have to be able to split up the same computation as though it were running on different actual computers.

Analogously, the computer would have to intelligently split up your piping models and add displaced anchors at the split point(s), and solve each one independently, moving displacements around until it gets all of them converge on equal forces and displacements.

My opinion is you'd need to eliminate CAESAR's convergence issues to make this viable.
