【求助】mpi vasp問(wèn)題
|
|||
|
我用openmpi在一臺(tái)機(jī)子上裝好vasp了 能并行運(yùn)行 在我機(jī)子上用同樣的方法卻運(yùn)行出錯(cuò) [laoshan.daoren:30001] *** An error occurred in MPI_Comm_rank [laoshan.daoren:30001] *** on communicator MPI_COMM_WORLD [laoshan.daoren:30001] *** MPI_ERR_COMM: invalid communicator [laoshan.daoren:30001] *** MPI_ERRORS_ARE_FATAL (your MPI job will now abort) mpirun has exited due to process rank 0 with PID 30001 on node laoshan.daoren exiting without calling "finalize". This may have caused other processes in the application to be terminated by signals sent by mpirun (as reported here). -------------------------------------------------------------------------- [laoshan.daoren:30000] 1 more process has sent help message help-mpi-errors.txt / mpi_errors_are_fatal [laoshan.daoren:30000] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages 何解阿? 急盼高人解答 [ Last edited by zzy870720z on 2010-12-8 at 22:28 ] |

你前面的問(wèn)題與此信息無(wú)關(guān)。解決此問(wèn)題: 還需要知道你是怎么并行提交你的作業(yè)的。另外你還可能需要先測(cè)試你的openmpi,看它能否正常并行運(yùn)行自帶的pi。還有你當(dāng)前提交的作業(yè)是計(jì)算多大的體系,有可能體系過(guò)大,內(nèi)存不足,那測(cè)試一個(gè)簡(jiǎn)單的小體系,看是否還存在同樣的問(wèn)題。 |

你可能對(duì)mpi的基本使用欠缺。 "mpirun -np 2 hello_c.c"這個(gè)是不能的。hello_c.c是源代碼。mpirun只能啟動(dòng)的是可執(zhí)行文件。因此你得先mpicc 編譯hello_c.c得到它的可執(zhí)行文件。 有關(guān)openmpi的基本使用方法,可參考: http://blog.chinaunix.net/u2/60913/showart_1134515.html http://www.huanglab.org.cn/node53.html |
