Hello,
I need feedback on the following proposed oscar package identifier/groups.
This relates to things like,
<provides>
<type>package</type>
<name>mpi</name>
</provides>
and the correlating <requires>, <conflicts> XML elements that can be used
in 'config.xml' files.
Up to this point we've not had too much overlap with oscar packages. The
primary usage was to differentiate MPI implementations, e.g., LAM/MPI,
MPICH. There are several packages being developed currently that need to
make use of groups that don't currently exist. Since this will be a
policy sort of things there needs to be an agreed upon list for package
authors to make use of so things will jive between packages.
The following list shows the proposed list, including some that already
exist as well as a couple of examples where these would be used.
mpi -- ex, LAM, MPICH <<already in use>>
switcher -- ex, Env-Switcher <<sort of odd case, already in use>>
allocation-mananger -- ex, Gold, QBank, ???
scheduler -- ex, MAUI
queue-manager -- ex, Bamboo, PBS
process-manager -- ex, MPD
job-manager -- ex, MPD?, Bamboo?
meta-scheduler -- ex, Silver?
meta-manager -- ex, ?<not sure on this one>? :)
OTHERS?
Lastly, it makes since that a package might have multiple <provides>. The
example I think of is PBS providing <queue-manager>, <process-manager> and
<scheduler> all in one package. I'm not sure if we can handle multiple
<provides> / <requires> blocks or if the element can have multple
sub-elements but this will also need to be honored for this to work
fully.
Please send your comments. I'm going to try and pool this information ASAP
b/c the SSS group is actively packaging software for a March 1 freeze date.
Thanks,
--tjn
