Subject: [OMPI users] newbe question

Hello.
Some times ago i run study MPI (openmpi).
I need to write application (client/server) runs on 50 servers in
parallel. Each application can communicate with others by tcp/ip (send
commands, doing some parallel computations).

Master - controls all clients - slaves (send control commands, if needed
restart clients). If master machine with server application die, some
other server need to recive master role and controls other slaves.

Can i do this things with openmpi? Or i need to write standart tcp/ip
client/server application?

I'm try to read some search results in google like this -
http://docs.sun.com/source/819-7480-11/ExecutingPrograms.htmlaopenmpi%
20orted%20persistent%20daemon
but orted return error:

orted --daemonize
[mobile:24107] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file
runtime/orte_init.c at line 125
--------------------------------------------------------------------------
It looks like orte_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during orte_init; some of which are due to configuration or
environment problems. This failure appears to be an internal failure;
here's some additional information (which may only be relevant to an
Open MPI developer):

  orte_ess_base_select failed
  --> Returned value Not found (-13) instead of ORTE_SUCCESS

Thank You. Sorry for my poor english.
