elastic moduli for large system by vasp5.2

[happyxiaohai]

greetings,
i am computing the elastic moduli for sro(srtio3)n ,i have very good results with n=1,n=2,but with n=3 ,sure it cost much more cpu time,the problem is in the OUTCAR i can never find the elastic moduli matrix,the OUTCAR just end with
--------------------------------------------------------------------------------------------------------


POTLOK: cpu time 0.02: real time 0.03

Finite differences progress:
Degree of freedom: 100/108
Displacement: 1/ 4
Total: 397/432
LATTYP: Found a simple tetragonal cell.
ALAT = 3.9361263503
C/A-ratio = 7.2009875784

Lattice vectors:

A1 = ( 3.9361263503, 0.0000000000, 0.0000000000)
A2 = ( 0.0000000000, 3.9361263503, 0.0000000000)
A3 = ( 0.0000000000, 0.0000000000, 28.3439969554)
Subroutine PRICEL returns:
Original cell was already a primitive cell.


Analysis of symmetry for initial positions (statically):

Routine SETGRP: Setting up the symmetry group for a
simple tetragonal supercell.


Subroutine GETGRP returns: Found 8 space group operations
(whereof 8 operations were pure point group operations)
out of a pool of 16 trial point group operations.


The static configuration has the point symmetry C_4v.

Analysis of symmetry for dynamics (positions and initial velocities):

Subroutine DYNSYM returns: Found 8 space group operations
(whereof 8 operations were pure point group operations)
out of a pool of 8 trial space group operations
(whereof 8 operations were pure point group operations)
and found also 1 'primitive' translations


The dynamic configuration has the point symmetry C_4v.

KPOINTS: Kpoints

Automatic generation of k-mesh.

Subroutine IBZKPT returns following result:
===========================================

Found 6 irreducible k-points:
