the problem as follows -> the problem are as follows


* Find the first error in the :code:`train.log`, :code:`server.log`, check whether other fault casued the problem, such as FPE, lacking of memory or disk.

* If network connection gave rise to the first error in the log, this may be caused by the port conflict of the non-exclusive execution. Connect with the operator to check if the current MPI cluster supports jobs submitted with parameter :code:`resource=full`. If so, change the port of job.

If so, change the port of job. => If the current MPI cluster does not support this parameter, change the server port and try agian.


* If the currnet MPI cluster does not support exclusive pattern, ask the operator to replace or update the current cluster.
