Hi,
I'm using the most recent release of g-Eclipse (Milestone 7). I've some
questions on g-Eclipse, the first being the most important as I need it
answered before I can encourage some of the users I support to start
using g-Eclipse.
* Are there plans to support MPI applications in the near future?
We have plans to check how to submit MPI applications. But as there was no
such request we did not put high priority to this task. Submission should
be possible, but I am not sure now how to put MPI job type into JSDL. In
addidion current version of our translator from JSDL to JDL does not
support MPI job type. So support for MPI most probably is possible but
needs investigation.
* Are there plans to support the job perusal features supported by glite?
Again, there was no such request yet. I see that our WMS Client have
methods for perusal, but they are not integrated with g-Eclipse. Again, we
need to investigate it further.
Could you please send us example JDLs with perusal features? The same for
MPI job type. It would be nice to have real use case for investigation
and such JDLs can help a lot.
* The g-Eclipse web page says that 'existing tools (such as the Migrating
Desktop....will be integrated.' What features of Migrating Desktop
will be supported? -- I assume that the roaming access server will be
used to funnel all communication from g-Eclipse on a user's desktop to
grid resources that may not be accessible directly from the user's
desktop (running the g-Eclipse instance), am I correct?
This is from historical reasons. During project preparations we planned to
have parts of MD integrated into g-Eclipse. But rather client and UI
functionality and not Roaming Access Server. Later it appeared that
techical problems did not allow us to take parts of MD directly.
In fact g-Eclipse offer now the same functionality (almost) as MD and adds
a lot of other features that are not in MD.
Almost, because in MD there is support now for MPI jobs and interactive
jobs, but step by step we will also add it to g-Eclipse.
Roaming Access Server will never be integrated with g-Eclipse, as the
assumption is that g-Eclipse works directly with middleware services. All
connection to middleware are done directly. (Or you can configure
Eclipse to use proxy for all connections)
