VASP cause computer freeze

Hello,

Did any one meet this kind of problem? We compiled vasp in our dual-core, four processors AMD computer in both parallel and serial version. The code works very well for small systems, like 2 or 8 atoms. However, when I go to supercell system, like 54, 64 atoms, or more, the vasp cause computer freeze at the random time without any error message.

First, we suspect it's hardware problem. But after check, we have not found any hardware problem. We also test our computer using other code, like espresso, to big system. The espresso works fine.

We use intel compiler and MKL lib.

Thanks very much for any hint.

you simply need more memory. rescale your k-mesh with the cell size (if you have not done so) and/or use more parallel nodes
