NCPU is used for SMP and Hybrid solvers. The correct command to run MPP LS-DYNA is,

/path/mpirun -np 128 /path/ls-dyna.exe i= input.k

If 128 MPI ranks are on different hosts, you may need a file with a list of hosts. Please see here for more information (https://ftp.lstc.com/anonymous/outgoing/support/FAQ/mpp.getting_started).
