Essentially, you ask if Boost.Build supports MPI. I think nobody ever tried,
so we can't claim such support. However:

> 1) compiling for MPI using the compiler wrapper scripts (mpicc, mpiCC)

If the question in replacing 'gcc' with 'mpicc' in command lines? Well, you
can specify a custom compiler name in 'gcc' invocation, or you can inherit
new "mpicc" toolset from gcc.jam and change it as needed.

I don't understand what you mean here, sorry.

> 3) running parallel unit-test applications with mpirun

It's possible to specify a command that's used to run unit tests, so the
command will be:

   mpirun whatever_unit_test_binary

> 4) support for submitting unit-tests to a queueing system like, for
> example, PBS

Again, you can specify "lancher" for unit tests, like this:

   unit-test whatever : whatever.cpp : <testing.launcher>PBS ;

and the command line will be:

   PBS whatever

I guess most of required machinery is needed, but since you're the one with
domain knowledge you'd need to try some things and then say what works and
what not and what should be fixed. I'd be happy if Boost.Build gets support
for MPI programs.
