Actually, we wouldn't have to modify the interface - just have to define a DB_RTE flag and OR it to the DB_INTERNAL/DB_EXTERNAL one. We'd need to modify the "fetch" routines to pass the flag into them so we fetched the right things, but that's a simple change. On Sep 18, 2013, at 10:12 AM, Ralp

I struggled with that myself when doing my earlier patch - part of the reason why I added the dpm API. I don't know how to update the locality without referencing RTE-specific keys, so maybe the best thing would be to provide some kind of hook into the db that says we want all the non-RTE keys?

I hit send too early. Now that we move the entire "local" modex is there any way to trim it down or to replace the entries that are not correct anymore? Like the locality? George. On Sep 18, 2013, at 18:53 , George Bosilca wrote: > Regarding your comment on the bug trac, I noticed there is

Regarding your comment on the bug trac, I noticed there is a DB_INTERNAL flag. While I see how to set I could not figure out any way to get it back. With the required modification of the DB API can't we take advantage of it? George. On Sep 18, 2013, at 18:52 , Ralph Castain wrote: > Thanks G
