By way of introduction, I just recently joined this list. I'm the
Ptolemy II software manager and I support the second proposal.

Erwin,
Absolutely! You should speak with Andrew Ross as soon as
possible.
Very excited,
Jay

Dear all,
I would like to propose 2 new projects :
- a set of APIs and impls in the domain of HPC, computing
grids etc
- a move of our Passerelle process engine from eclipselabs
to a formal eclipse project
Would this be of interest for science IWG? If so, read on
;-)...
Any feedback is of course welcome!
kind regards,
erwin
More info :
=========
1. in the HPC domain :
- APIs and impls for accessing computing grids (cfr DRMAA,
SGE, SLURM, ...)
- other clustering-related tools
- memory grids
- etc
This would contain an initial code drop from the DAWN
repos at github with just the DRMAA and SGE grid access.
Matt Gerring (DAWN lead) supports this move.
In the near future we would be extending this to a
DRMAA-implementation for SLURM.
Another next task is upgrading from DRMAA v1 to v2.
Other topics are less/not concrete right now, and would
depend on requests from science IWG or from additional
committers.
Open questions :
- What would be a good name? Can we claim a generic name
like "science HPC" or so? (and then hope that there's
sufficient participation to enlarge the scope to other
HPC-related tools)
- Where to put this? Is this a sufficient scope for a new
eclipse project? Or should it be a component of a parent
project?
- I guess this would become a technology project?
2. a move of our Passerelle workflow
engine&workbench from the current eclipselabs@Google
hosting to a formal eclipse project
The initial code drop would include a minimized Passerelle
core, built on top of a new OSGi-ified version of Ptolemy
(the underlying actor-based hybrid modeling software of UC
Berkeley)
(Ptolemy is and would remain hosted by UC Berkeley, so
their sources would not move to eclipse)
The current GEF-based Passerelle model editor
would no longer be maintained, and would be replaced by an
EMF&Graphiti-based one that would become the future
Ptolemy model editor.
(i.e. the editor would no longer be specific for
Passerelle)
For the longer term we would be extending Passerelle
towards the needs for "reproducible science" (cfr
http://www.reproduciblescience.org).
Open questions/issues :
- as Passerelle is the basis for our production software,
with frequent releases, we can't be blocked for too long
in an incubation phase (which seems to prevent formal
releases).
- would this be a technology or a tools project?
