[ptp-dev] PTP extension points for job launch/completion

[Dave Wootton <dwootton@xxxxxxxxxx>]

I'm working on other Eclipse plugins
that are not part of PTP. I want to allow users to use the PTP launch configuration
dialog to run their parallel applications. One of the things I need on
order for that to be useful to my plugins is notification that the job
was started and that the job completed, with completion status. 

I was thinking that this might be implemented
as one or more extension points in PTP that my plugin could register with
and then add itself as a listener for the events it needed. 

I think the only notifications I would
need are that the application was started, along with the path name of
the application, so I could know that my application has started, and a
notification that the application completed, along with the same pathname
and completion status. 

Other sorts of information that might
be more generally useful would be notification that the job was submitted
and maybe a task to node mapping. This mapping might be useful to me in
the case where the application ran in  a filesystem that was not globally
shared in the cluster, where I might have to retrieve data off individual
nodes. This isn't of great importance to me since there would be other
problems related to accessing those nodes to solve as well.

The other thing I think I need is a
way to create a new launch configuration that the user would see in the
launch configuration dialog when he opened the launch configuration dialog.
Currently, my plugin is not aware of the Eclipse project concept. All it
has is the pathname of an executable that it wants to run. I've found that
if I open the launch configuration dialog, that I can select an arbitrary
project and then specify an executable, even if that executable has nothing
to do with the project, so if I had the ability to create a launch configuration,
I think that would be helpful.

I haven't completely thought through
the details of creating a launch configuration, or if dynamically creating
a launch configuration  is even the right way to hook into the PTP
launch configuration dialog in the first place. I'm interested in suggestions
that would be a good match with PTP.
