[mvapich-discuss] BLCR+FTB+MVAPICH2:problems about migration between two nodes

[hljgqz]

 To whom it may concern,
        I have two problems when using BLCR+FTB+MVAPICH2 .I can restart mpi job in the original nodes,
But I can't restart mpi job no different sets of nodes.
1)I can't restart the mpi job on a different node. I do as the userguide said.
I have two nodes named node1 and node3 .
Firstly, I run " mpirun_rsh -np 2 -hostfile hosts ./proc  "on node3, hosts file is consist of node1:4
Then I run cr_checkpoint -p <pid> .AND I can restart it using the original hosts file.
BUT if I change hosts( the hostfile ) to node3:4 as the userguide said and restart the job but it doesn't work ,and report error :
[node3:mpispawn_0][child_handler] MPI process (rank: 1, pid: 5174) terminated with signal 4 -> abort job
[node3:mpirun_rsh][process_mpispawn_connection] mpispawn_0 from node node3 aborted: MPI process error (1)
2)I tried mpirun_rsh -np 4 -hostfile ./hosts -sparehosts ./spare_hosts ./prog , BUT it doesn't work ,
and give back the messages :
[root at node3 node0]# mpirun_rsh -np 4 -hostfile ./hosts -sparehosts ./spare_hosts ./hello
[root at node3 node0]# [FTB_WARNING][ftb_agent.c: line 46]FTBM_Wait failed 1
my configuration:
[root at node3 node0]# mpiname -a
