6310361532 At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here: 
https://svn.open-mpi.org/trac/ompi/wiki/ProcessPlacement

The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation.

In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions:

1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior.

2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation.

3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so.

As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes.

f08b8bf2d4 Per this thread: 
http://www.open-mpi.org/community/lists/devel/2011/10/9878.php

I am making a final decision to decide the behavior of what happens
when an MCA parameter is re-registered and changes types.  In
developer builds (i.e., OPAL_ENABLE_DEBUG==1), a show_help message
will be displayed.  In all builds, an error status will be returned.
Specifically, the logic looks like this:

{{{
    if (detect_re-registration_with_type_change) {
#if OPAL_ENABLE_DEBUG
        opal_show_help(...);
#endif
        return OPAL_ERR_VALUE_OUT_OF_BOUNDS;
    }
}}}

If someone would like to change this behavior, they are welcome to do
so.  :-) I am committing this so that ''some'' action occurs (rather
than talking about the issue and then nothing happens).
