Hello Brian,
First have a merry Christmas and a happy new year :) and thank you for your
answer.
Now we have been looking at the code, it looks like it's based on LAM MPI's
debug layer and we are still trying to figure out how it's running. We
haven't spent a lot of time on reading the source though, got a lot to do
but we're going to be more busy in January.
Our goal was to split the graphical part and the "core" part, each part
communicating though XML streams. That means, we should be able to redirect
the libxmpi outputs to XML objects, this should bring more flexibility in
the GUI part. But before we do that, we have to figure out how the core
engine works (how it runs the program, how it monitors it, how they
interact, ...). We are looking at the code, but a quick technical
explanation from you core developers would be real handful so we can have a
rough meaning of how to start with ;)
Thank you,
Fred
PS : Do you mean LAM MPI is dead and Open MPI is its successor ?
