Tim,
Can you try the attached patch and post the log output?
System::project_vector() has a bit of communication in it, but the
ProjectVector::operator() does not. I'd like to see the breakdown.
Also,
(1) how may systems do you have?
(2) have you added additional vectors?
(3) how many variables, and of what type?
(4) what is the architecture of the machine you are running on? Processors
and interconnect?
