Bulk Surface relaxation doesn't proceed

Hi there,

I tried to relax the bulk surface (IBRION = 2). But The job doesn't proceed. In the OSZICAR file it wrote nothing.

The OSZICAR file is as follows:

N E dE d eps ncg rms rms(c)


After that it wrote nothing.

The OUTCAR file is as follows:


total amount of memory used by VASP on root node 539721. kBytes
========================================================================

base : 30000. kBytes
nonlr-proj: 50828. kBytes

INWAV: cpu time 0.00: real time 0.00
Broyden mixing: mesh for mixing (old mesh)

(NGX =216 NGY =192 NGZ =252)
gives a total of 63425 points

Could you please tell me what is the problem??

Hi Alex, i used 16gb memory. IS that OK? How to solve this...any suggestion?
