| VASP found 192 degrees of freedom |
| the temperature will equal 2*E(kin)/ (degrees of freedom) |
| this differs from previous releases, where T was 2*E(kin)/(3 NIONS). |
| The new definition is more consistent |

What is the mean of this warning? How to deal with it ? Any reply will be appreciated.

simply ignore it. As written in the warning anyway, it is just a hint that the way the number of degrees of freedom is calculated has been changed compared to older vasp releases.

Thank you very much.But I meet another problem when I caculate the MD with VASP. At the end of running, it is not terminat normally, but with
p0_30237: p4_error: interrupt SIGSEGV: 11
rm_l_1_30250: (1709.467517) net_send: could not write to fd=5, errno = 32
forrtl: error (69): process interrupted (SIGINT)
p1_30241: (1709.467517) net_send: could not write to fd=5, errno = 32
p0_30237: (1711.548285) net_send: could not write to fd=4, errno = 32
What is the meaning of that ? How can I deal with it.

sorry, this is a networking problem of your system, not related to vasp
directly. Ask your sys admin to check the communication between the nodes.
