[OMPI devel] User request: add envar?

2008-07-11 Thread Ralph H Castain
Yo folks For those not following the user list, this request was generated today: Absolutely, these are useful time and time again so should be part of the API and hence stable. Care to mention what they are and I'll add it to my note as something to change when upgrading to 1.3 (

[OMPI devel] SM latency regression

2008-07-11 Thread Terry Dontje
Has anyone else seen the trunk incur approximately a 10% increase in latency? I think this has happened in the last couple weeks. I have verified that it isn't due to the recheck put into the sm_component_progress. I am about ready to try and track this down but wanted to throw this out ther

Re: [OMPI devel] PLM consistency: priority

2008-07-11 Thread Ralph H Castain
Ummm...I actually was talking about the "PLM", not the "PML". But I believe what you suggest concurs with what I said. In the PLM, you could still provide multiple components you want considered, though it has less meaning there. My suggestion really is only that we eliminate the params to adjust

Re: [OMPI devel] PLM consistency: priority

2008-07-11 Thread Aurélien Bouteiller
We don't want the user to have to select by hand the best PML. The logic inside the current selection process selects the best pml for the underlying network. However changing the priority is pretty meaningless from the user's point of view. So while retaining the selection process includin

[OMPI devel] PLM consistency: priority

2008-07-11 Thread Ralph H Castain
Okay, another fun one. Some of the PLM modules use MCA params to adjust their relative selection priority. This can lead to very unexpected behavior as which module gets selected will depend on the priorities of the other selectable modules - which changes from release to release as people independ

Re: [OMPI devel] PLM consistency: launch agent param

I suppose we could even just make it an mpirun cmd line param, at that point. As an MCA param, though, we have typically insisted on a particular syntax that includes framework and component... On 7/11/08 8:41 AM, "Don Kerr" wrote: > For something as fundamental as launch do we still need to sp

For something as fundamental as launch do we still need to specify the component, could it just be "launch_agent"? Jeff Squyres wrote: Sounds good to me. We've done similar things in other frameworks -- put in MCA base params for things that all components could use. How about plm_base_launc

Sounds good to me. We've done similar things in other frameworks -- put in MCA base params for things that all components could use. How about plm_base_launch_agent? On Jul 11, 2008, at 10:17 AM, Ralph H Castain wrote: Since the question of backward compatibility of params came up... ;-)

Since the question of backward compatibility of params came up... ;-) I've been perusing the various PLM modules to check consistency. One thing I noted right away is that -every- PLM module registers an MCA param to let the user specify an orted cmd. I believe this specifically was done so people
