Freely admitted laziness on my part (read: not enough cycles in the day to do what Cisco already pays me to do...). :-(

Same issue here! Maybe we should Google Wave it... ;-)

I can't tell you how much we appreciate these reports.
I know exactly the position you're in; I did the same thing years ago (ick!) with the is (was!) the MPI C++ bindings and with Object Oriented MPI (OOMPI). They were portable packages that ran on lots of different MPI's; their respective test suites found lots of problems in various MPI implementations. The LAM/MPI guys sent me a t-shirt for my efforts, which pretty much locked in my long slide into the deep, dark world of MPI implementers. ;-)
