have you tried running charmrun in verbose mode?
can you connect to the other nodes without a password?
do you have to use rsh or ssh?
can you run any of the charm++ tests?
have you tried a precompiled namd package?
what kind of interconnect does your cluster have?

what do you mean by "seems not helpful"? did you follow
the suggestion and examples as given there?

as you can see from the questions above, there is a *ton*
of things that you can do, that are described in the
documentation and that common sense will tell you.
