[mpich-discuss] Fatal error in PMPI_Bcast: Other MPI error, error stack:

[游手好闲]

Hi ，
 My hosts:
 hksbs-s13.com:8
hksbs-s11.com:8
  
 When i run in one node,it is ok.
 [root at hksbs-s13 examples_collchk]# mpiexec -f hosts -n 8 ./time_bcast_nochk
time taken by 1X1 MPI_Bcast() at rank 0 = 0.000005
time taken by 1X1 MPI_Bcast() at rank 1 = 0.000002
time taken by 1X1 MPI_Bcast() at rank 2 = 0.000003
time taken by 1X1 MPI_Bcast() at rank 3 = 0.000002
time taken by 1X1 MPI_Bcast() at rank 4 = 0.000004
time taken by 1X1 MPI_Bcast() at rank 5 = 0.000002
time taken by 1X1 MPI_Bcast() at rank 6 = 0.000003
time taken by 1X1 MPI_Bcast() at rank 7 = 0.000002
  
 but when i connect to other node, it failed
  
  
 [root at hksbs-s13 examples_logging]# mpiexec -f hosts -n 9 ./srtest

 when i ssh the other node, for example
  
 
[root at hksbs-s13 examples_logging]# ssh hksbs-s11.com

[root at hksbs-s11 ~]#

  
 it works.
  
 How can check the reason?
