In principle, the nlvdw module requires (much) more RAM than lapw0, lapw1, etc. do.

For such large systems you need to do MPI parallel calculations by adding a line "nlvdw:..." in the file .machines (see user's guide for detail) and using option -p (runsp_lapw -p ...). You should also run the other modules (lapw0, lapw1, lapw2) in parallel. Beside this, I will very soon (probably tomorrow) send to the mailing list updated Fortran files for the nlvdw module. With these updates, MPI calculations should be much faster. F.
