[mvapich-discuss] Does mvapich2 really support dynamic process management?

[马凯]

I tried the examples of parent and child in the mvapich2-2.1rc2/examples, but they didn't work.
This is my compile commands:
#mpicc -o parent parent.c
#mpicc -o child child.c


This is my run command:
#mpirun_rsh -np 4 -hostfile hf MV2_SUPPORT_DPM=1 ./parent


And the content of hf is: 192.168.2.1
This is the IP of IB port on my node.


After run the command, the parent will be stuck. Then I added some output tips, and I found the MPI_Comm_spawn would never return.
It seems that the child had been start, but the MPI_Init in child would not return.


Why this happened? Does mvapich2 really support dynamic process management or not?
Could some one give some help?
Thanks
