We report on the progress of our implementation of the configuration-selecting multi-reference configuration interaction method on massively parallel architectures with distributed memory, which now permits the treatment of Hilbert spaces of dimension O(10~(12)) about 20,000,000 of which can be selected in the vari-ational subspace. We provide scaling data for the CPU time of the code for the IBM/SP3 and the CRAY-T3E. We present benchmark results for two selected applications: the isomers of diritrosoethylene and the electronic structure of two members of the transition metal dihalide family: VF_2 and VCl_2.
