看楼主的语言习惯是港台的，我还是用英语回复好了。 The error info can be found at the end of xxx.log file if you ran Abinit with command: abinit < xxx.files >& xxx.log, otherwise, it displays in your terminal. I am not sure which kind of "error" you met, or what means "cannot calculate". By guessing, displacements of ion(s) broke the symmetry, thus the convergence of response function may become more difficult. |

Actually, the error info you provided was not really the proper one, since it was just a stop signal from MPI code, instead of that from Abinit. Why don't you attach your full log or output file here? You can edit your first post and upload the file as accessory. Further, you may download my tutorial about Abinit from the ??????? broad. That will give you some idea for finding error info from Abinit. ?????????δ???????????????????????MPI??????????????????Abinit??? ??????log???????????????????????Σ????????????????????????? ????????????????????????????Abinit??????????????β???Abinit?????????? |

I have checked it, the error info was as: Therefore, I wanna ask a question, which version of MPI you are using now, MPICH1? Since I can just find p4_error from MPICH1 or P4 but not from modern MPICH2 and OpenMPI. Would you like to take a look at your mpi version by : mpiexec -info ? Of course, some person reported that p4_error may be caused by network problem among nodes, I am not sure whether you are using cluster or workstation (16 cores Xeon platform could be multi-CPU workstation). But if you were using the later one, it does not make sense to discuss about network problem. |

It could be an Abinit problem, even though I still think it is higher possible raised from the old version of MPI. If you wanna calculate the 3rd-order deviation of energy ( anharmonic phonon), why not giving a try to Quantum-ESPRESSO? It is normally stable for response function issues. |
