Hello, I found [1][2] that it is possible to
change the compiler for C and C++ source blocks. I would like to
know if there is a way to add =mpirun -np 2= (where 2 can be any
other number) to run the resulting executable. Thanks!

I guess you want to run the executable after it has been compiled,
with a command like this one:
mpirun -np 2 /tmp/babel-ad2pdk/C-bin-JTvjS4
Currently it is not possible.
There is the :cmdline specifier which adds
parameters to the executable, like this:
#+begin_src C++ :cmdline AAA BBB CCC
int main (int nargs, char** argv)
{
// argv will be {
// "/tmp/babel-ad2pdk/C-bin-JTvjS4",
// "AAA",
// "BBB",
// "CCC"
// }
}
#+end_src
Those parameters come AFTER the executable,
whereas mpirun should come BEFORE the executable.
An extension may be written in ob-C.el, in
the org-babel-C-execute function.
The relevant line is:
(concat tmp-bin-file cmdline)
