Thank you, ipsecog !
I just run it in my PC with one CPU because the submitting job is simple(just needing about twenty minitutes).
More detail:
When I caculate at 0V,0.5V,-0.5V,1.0V, -1.0V , my job are all successful, but when I change it to 1.5V,-1.5V, 2.0V,-2.0V, the error happens. Another, it seems that they can still get the whole out document.
So, it confuses me!
Thanks!
