This goes against everything I have done with the KrylovSchur solver!

Can you confirm (to yourself and to me) that your system really is using
multiple processors and not multiple threads? If you can answer that I may
take a look at your code. Show me some output please.

How do you invoke your code on the command line? mpicc???
