集群mpich2調(diào)試出問題mpdboot -n 無法啟動
|
|
|
在集群搭建的時候,用的是mpich2-1.4.1p1,ssh nfs nis都已經(jīng)OK,現(xiàn)在卡在mpi的調(diào)試上,一直無法啟動跨節(jié)點的mpi,總是出現(xiàn)以下的錯誤,請問有解決方法不?都按照集群mpi進行配置了(mpd.hosts .mpd.hosts .mpd.conf mpd.conf,然后都是600的權(quán)限),還是不行,是否需要重裝mpich? [root@node-1 ~]# mpdboot -n 4 -f mpd.hosts Traceback (most recent call last): File "/usr/local/bin/mpdboot", line 482, in ? mpdboot() File "/usr/local/bin/mpdboot", line 234, in mpdboot (k,v) = kv.split('=',1) ValueError: need more than 1 value to unpack 或者是這樣的錯誤 [lixb@node-1 ~]$ mpdboot -n 2 -f mpd.hosts unable to open (or read) hostsfile mpd.hosts |

你好,非常感謝啊。 我直接運行mpirun的時候出現(xiàn)了這樣的問題:請問有遇到過嗎?謝謝啊 [lixb@node-1 ~]$ mpirun -machinefile /usr/local/mpich2-1.4.1p1/bin/nodes.LINUX -np 16 ./hellocluster >out1 -------------------------------------------------------------------------- Open RTE detected a parse error in the hostfile: /usr/local/mpich2-1.4.1p1/bin/nodes.LINUX It occured on line number 2 on token 5: node-2 -------------------------------------------------------------------------- [node-1:25170] [[64214,0],0] ORTE_ERROR_LOG: Error in file base/ras_base_allocate.c at line 236 [node-1:25170] [[64214,0],0] ORTE_ERROR_LOG: Error in file base/plm_base_launch_support.c at line 72 [node-1:25170] [[64214,0],0] ORTE_ERROR_LOG: Error in file plm_rsh_module.c at line 990 -------------------------------------------------------------------------- A daemon (pid unknown) died unexpectedly on signal 1 while attempting to launch so we are aborting.
