Steps to troubleshoot 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 the first error in server.log says "Address already used", this may be caused by the port conflict of the non-exclusive execution. Connect the sys-admin to check if the current MPI cluster supports jobs submitted with parameter :code:`resource=full`. 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. +* If the current MPI cluster does not support exclusive pattern which allows a process to occupy the whole node, ask the administrator to replace or update the this cluster. -- GitLab
