What I mean by pure OO C++ is full blown patterns implemented using dynamic polymorphism etc, etc. You go through about 3 or 4 layers of indirection via abstract classes to go from caller to callee. You need 6-8 windows open on the screen just to understand what some bit of code is doing. And yes, its even worse when it's asyncronous threaded code (which I've had to do my share of).
By comparison, doing MPI programming using a simple class reflection library is total dream. And that's even without the sophistication of using TotalView. See some of my papers on ClassdescMP. My point wasn't that OO isn't useful or has its place. It is definitely an important technique. Just that when overused, it actually adds to the complexity of the solution.
