hi,everyone!

when i run a supercell using vasp4.6 on ibm sp3, the following error appear, i don't know this means what !
thank you!!



POSCAR found : 3 types and 108 ions

| ADVICE TO THIS USER RUNNING 'VASP/VAMP' (HEAR YOUR MASTER'S VOICE ...): |
| |
| You have a (more or less) 'large supercell' and for larger cells |
| it might be more efficient to use real space projection operators |
| So try LREAL=.TRUE. in the INCAR file. |
| Mind: If you want to do an extremely accurate calculations keep the |
| reciprocal projection scheme (i.e. LREAL=.FALSE.) |

I am very confused by this error! ：Segmentation fault (core dumped) ，i don't know it means what!
I have tested many crystal structure calculation using vasp4.6 on ibm sp3 machine successfully.

Probably your memory is not large enough. Adjust the input parameters which
influcence the memory size (PREC, nr. of k-points,..)
