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?
