[SAGA-RG] planning for OGF-30 interop demo

[Andre Merzky]

Hi all, 

as most of you should now by now, we plan a SAGA interop demo for
OGF30 in Brussels (http://www.ogf.org/OGF30/).  In order to pull
that off successfully, we need to start to define

  - participants
  - scope
  - implementations to be used
  - interop demo scenario

From the top of my head, I would think that the following parties
might be interested to team up resources (endpoints, code, people)
to get things in place:

  - VU Amsterdam
  - IN2P3, France
  - CCT, LSU
  - KEK/Naregi
  - RAL, UK

It would be great if each party could let us know explicitely if
they are interested in participating!  Did I miss anybody?

We have the following bits and pieces which may, or may not, play a
role in the interop demo

  implementations:
    JavaSAGA
    JSAGA
    SAGA-C++
    PySAGA (over JavaSAGA)
    PySAGA (over JSAGA)
    SAGA-Python (over SAGA-C++)
    command line tools for most of the implementations

  functionality:
    Job Submission (all)
    Data transfer / access (all)
    Advert Service (not JSAGA I think, not in PySAGA)
    Replica Management (not JSAGA?)
    Service Discovert (not in JSAGA?  not in PySAGA)

  backends:
    local  (all)
    globus (all)
    ssh    (all)
    aws    (all?)
    glite  (all?)
    bes    (all?)

  Infrastructures
    local institutions
    teragrid
    loni
    naregi
    What about European Grids?
    

Again, is there something I miss?

PySAGA appears to be a great integration point, and SAGA-C++ intents
to support it very soon, too - but it is not sure that we manage to
do that before OGF30.  

A simple interop demo would be to submit the same job (NOT
/bin/date) to a set of resources in the various infrastructures
discovered via SD, from various tools.  A job submitted via python
for example should be monitorable from C++ tools, and output could
be reaped via PySAGA-over-JSAGA, etc.

The above is just an initial input, to get the discussion and
planning started.  Please feed back, and complete the item lists
above.  Once we have those lists complete, we should be able to come
up with some more or less realistic scenario.

I'll mirror thiss list on our wiki at GridForge, so that we can edit
things in place.  Feel free to discuss on the list though, I'll try
to keep the thread in sytnc with the wiki.

Best, Andre.
