Re: [OMPI users] Using PMI as RTE component

[Ralph Castain]

It's my fault - as release manager, I should have spotted that component 
sneaking into the release branch back in the 1.7 series, but I missed it. I 
have deleted it now as it was never intended to be released.

Sorry for the confusion.

 Hello,
 
 I am trying to utilize pmi instead of orte, but I come across the 
 following problem.
 I do configure using --with-slurm=[slurm installation path] and

 After compiling, I run the executable using:
 $srun -n 2 --mpi=pmi2 ./executable
 
 However, this still goes through orte component, not the pmi.
 Am I missing something when I configure?

Re: [OMPI users] Using PMI as RTE component

[Hadi Montakhabi]

Ralph is right.
I used 1.8, and after digging into it, I noticed it doesn't even compile
the pmi component. When I tried to configure without orte, I could see the
errors while compiling.
It looks like it is well broken!

Peace,
Hadi

Re: [OMPI users] Using PMI as RTE component

[Ralph Castain]

Josh - he's talking about the PMI component in ompi/mca/rte. It generally 
doesn't work.

Re: [OMPI users] Using PMI as RTE component

[Joshua Ladd]

Hadi,

Is your job launching and executing normally? During the launch, frameworks
are initialized by opening all components, selecting the desired one, and
closing the others. I think you're just seeing components being opened,
queried, and ultimately closed. The important thing is knowing if PMI was
selected.  Set: -mca ess_base_verbose 5 -mca plm_base_verbose 5 -mca
grpcomm_base_verbose 5.

Re: [OMPI users] Using PMI as RTE component

[Ralph Castain]

I wouldn't trust that PMI component in the RTE framework - it was only created 
as a test example for that framework. It is routinely broken and not 
maintained, and can only be used if forced.

Is this on the trunk? Or are you using the 1.8 series? If the latter, that 
component shouldn't even be there.

Re: [OMPI users] Using PMI as RTE component

[Hadi Montakhabi]

By "goes through orte component", I meant it does go into rte_orte_open
function in rte_orte_component.c.
Let me try to formulate my question in a different way:
There are two components in the rte framework, namely orte and pmi.
The question is whether pmi could be used independent from orte? Or it
needs orte to function?

Peace,
Hadi

Re: [OMPI users] Using PMI as RTE component

[Ralph Castain]

What do you mean "goes through orte component"? It will still call into the 
orte code base, but will use PMI to do the modex.
