大家好，交流下集群程序使用遇到的问题，多谢。 [node21:10714] *** An error occurred in MPI_Comm_rank [node21:10714] *** on communicator MPI_COMM_WORLD [node21:10714] *** MPI_ERR_COMM: invalid communicator [node21:10714] *** MPI_ERRORS_ARE_FATAL: your MPI job will now abort -------------------------------------------------------------------------- mpirun has exited due to process rank 3 with PID 10711 on node node21 exiting improperly. There are two reasons this could occur: 1. this process did not call "init" before exiting, but others in the job did. This can cause a job to hang indefinitely while it waits for all processes to call "init". By rule, if one process calls "init", then ALL processes must call "init" prior to termination. 2. this process called "init", but exited without calling "finalize". By rule, all processes that call "init" MUST call "finalize" prior to exiting or it will be considered an "abnormal termination" This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). -------------------------------------------------------------------------- [node21:10707] 7 more processes have sent help message help-mpi-errors.txt / mpi_errors_are_fatal [node21:10707] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages 新编译的计算程序siesta，用qsub job提交上去很快结束提示的信息，能否帮忙诊断一下情况。在另外一个集群上编译后直接用mpirun -np 4 siesta可以顺利执行的，不知道为何在新集群用qsub出现这个问题，这个新集群不让进入到子节点，所以必须要解决这个问题才行，多谢了。 不知道是哪里的问题，之前在该环境并行编译的lammps和vasp都使用很顺利，就是siesta用qsub提交作业总是无法正常计算，但是并行编译的siesta在另外环境下的子节点用mpirun -np 4 siesta执行很顺利，纠结了。 哦，登录节点上mpirun我试过的，请帮忙看看，感觉被管理员设置了也无法用： mpirun -np 4 siesta libibverbs: Warning: RLIMIT_MEMLOCK is 32768 bytes.

我前两天用vasp也出现类似问题，刚刚解决～ The OpenFabrics (openib) BTL failed to initialize while trying to allocate some locked memory. This typically can indicate that the memlock limits are set too low. For most HPC installations, the memlock limits should be set to "unlimited". The failure occured here: Local host: node21 OMPI source: btl_openib_component.c:1055 Function: ompi_free_list_init_ex_new() Device: mlx4_0 Memlock limit: 65536 You may need to consult with your system administrator to get this problem fixed. This FAQ entry on the Open MPI web site may also be helpful: http://www.open-mpi.org/faq/?category=openfabrics#ib-locked-pages -------------------------------------------------------------------------- -------------------------------------------------------------------------- WARNING: There was an error initializing an OpenFabrics device. 上面那个网址里15、16、17说的挺清楚的，我的情况是在每个节点ulimit -a显示locked memory都正常，可就是出错说内存分配不正常，那个网址里说可能是登录时没有正常执行系统所设的locked memory，或者作业调度系统没有分配给应用程序足够大的内存，最后重启了一下每个节点的pbs调度系统的守护进程，问题解决了～ 或者你可以在mpirun前边儿加上ulimit -l unlimited，用qsub提交下试试 希望以上信息对楼主有用～ |
