- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

* THIS FUNCTION NEEDS TO CHANGE POST-1.0.

* After 1.0, this function, and the rds/hostfile need to change to
|
|
* clean up properly. They're not "broken" right now, so we're not
|
|
* fixing them. But they're implemented wrong, so they should be
|
|
* adapted to the model that they're supposed to implement, not the
|
|
* workarounds that they currently have. The end result will be much,
|
|
* much cleaner.
|
|
*
|
|
* Specifically, the rds/hostfile currently puts all of its nodes on
|
|
* the resource segment *and* the node segment. It should not. It
|
|
* should only put its nodes on the resource segment, appropriately
|
|
* tagged that they came from a hostfile. The ras/hostfile should
|
|
* then examine the resources segment and pull out all nodes that came
|
|
* from a hostfile and put them on the nodes segment.
