I have installed apbs enabling mpi, it works but it detects only one cpu in my core duo system. Strictly speaking it's correct, but not quite what I expected. I would like to know more about this behaviour, is it due to my misconfiguration of apbs, mpi, kernel or other factors? Besides this, trying to make apbs detect my two cores I tried also mpich2 and lam-mpi as mpi implementations. Using both of them and recompiling maloc apbs will complain that maloc has not been compiled with mpi support, and will keep mpi out of the build process. maloc however doesn't print any warning.
