%description
Aims to utilize model-based clustering (unsupervised) for high dimensional
and ultra large data, especially in a distributed manner. The code employs
'pbdMPI' to perform a expectation-gathering-maximization algorithm for
finite mixture Gaussian models. The unstructured dispersion matrices are
assumed in the Gaussian models. The implementation is default in the
single program multiple data programming model. The code can be executed
through 'pbdMPI' and MPI' implementations such as 'OpenMPI' and 'MPICH'.
