Thank you Jeff,
Despite some names doesn't make sense they are very original ;)
The names mostly reflect our horrid ability to name things. :-)On May 15, 2008, at 2:37 PM, Caciano Machado wrote:

You are correct about "DR" -- but note that it was never finished.
It's probably only pseudo-operable; it doesn't do everything that it
was designed to do because the DR developers got other priorities and
never finished it.
OB1 = Obi-Wan Kenobi from Star Wars (we couldn't think of any good
name at the time and really needed a name so that we could start
--> similarly, the "r2" BML is R2-D2 from Star Wars
CM = "Connor MacLeod" from The Highlander movie, a reference to the
fact that "there can only be 1" ...MTL module in an MPI process (vs.
OB1, which can have as many BTL modules as are relevant)
There you go -- a little insight into the warped minds of those of us
who bring you Open MPI. Ok, I'm a little embarrassed now. ;-)
