We need different parsing functions so that we don't allocate duplicate buffers for the same data. You need to allocate buffers when getting the raw integers and you need to allocate other (duplicate) buffers when converting the raw integers to MPI. Using the proposed API each user can select the format of data he wants, eliminating the need of a double conversion (with its drawbacks: duplicate buffers, unnecessary cycles).
