Dear Erwin,
I'll reach out off-list to help get you started.
Kind regards,
Andrew

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?
