Hey all,

Sorry for my lag on this thread, I'm still settling back into
Bloomington and catching up on email traffic.

This is certainly my fault WRT the addition of the RDS call to
orte_init_stage1(). I never tested the case where a process is a
singleton and not the seed. :(

Since the RAS (or functionality represented by this subsystem) was
exposed at this level, it was assumed that the RDS is also active at
this time. The addition in orte_init_stage1 was to add host entries to
both the RAS and RDS (instead of just the RAS) when we start a
singleton process.

A quick repair would be to protect the RDS section from all non-seed
processes. E.g.
if(orte_process_info.seed) {
   ret = orte_rds.store_resource(&rds_single_host);
   if (ORTE_SUCCESS != ret ) {
     ORTE_ERROR_LOG(ret);
     return ret;
   }
}

An additional fix would be to add a call to the rmgr to setup singleton
processes, thus pulling out the 'singleton process only' chunk of code
from the orte_init_stage1() and into the rmgr. Something like:

if (orte_process_info.singleton) {
   if (ORTE_SUCCESS != (ret =
orte_rmgr_base_setup_singleton(my_jobid,...))) {
       ORTE_ERROR_LOG(ret);
       return ret;
   }
}

Currently this would only contain the addition of the singleton process
to the RDS and RAS, but Ralph mentioned last week that he ran across
some other 'singleton only' stuff that might be needed.

Is there a design issue in adding this functionality to the rmgr, with
the proper protection around access to the RDS?

I guess my overall argument is that the RDS should be called in the
singleton+seed case since we are adding resources to the allocation
[RAS], and thus the resources globally available [RDS]. Do we assume
that if the process is a singleton and not the seed then it has already
been placed in the RDS, and only needs to confirm it allocation in the
RAS? Shouldn't that registry handling only happen at the seed level if
we assume it has launched the singleton process?

It is likely that I could have things confused a bit with how we define
a singleton process, and how they are created with relation to the
seed.

As a general bug notice in ORTE: There is an outstanding bug in the
proxy/replica NS components when creating new cellid's that I ran
across last Friday, before I had to stop. Something is getting mangled
in the packing of the command sent to the seed. I had to wrap up before
I could seek a good fix, just enough to characterize the problem.

Thoughts?

Sorry for causing trouble,

Josh
