This is certainly a possible limitation. The way sander handles
parallelization in minimization is completely different than what is used for
molecular dynamics, and it could well be that minimization is limited to
2 threads (i.e. -np 2) for TI.

I'm not quite sure why you are doing minimization with TI anyway, but I
suggest sticking with what works and using just 2 threads.

good luck...dac
