Once the daemons are launched, we then tell the daemons what processes each is to run. So it is a two-stage launch procedure.
Ralph after starting the orte_deamon
- what is the role of ssh
- Also i am assuming HNP is created before using ssh. Am i right ?
- Also Ralph i would to know how i can tell the daemon to run a process ?
Ralph i am tying to create run a simple experiment where i can create a simple process between two computer using SSH module without using mpirun. I would to hack the mpi library so that i can send a simple "Hello World " from process A running in computer A to process B running in computer B. I would be create both the process myself. HOPE I AM BEING CLEAR.
Basically what i am saying is i would to create the MPI_COMM_WORLD comprising of two process Process A and Process B. For that i would to create a functions called Create_Process_A and Create_Process_B and Send_Message by utilizing Open MPI source code.
Also, I know i should be looking into PLM subsystem, RMAPS subsystem, ODLS subsystem, and
ORTED subsystem. But Ralph if you guide me a bit i can finish the experiment with less sleepless night, headache, and stress.
