Re: AW: [geclipse-dev] PBS implementation 
Hi Thomas
This would be very nice for the Batch Editor. I looked into using gLogin in addition to ssh for the Batch Editor a while back, but realized that it would not be as easy as I though. Now if what you are proposing is provided that would be great. Will you implement this? And what would be the timeframe? 

Thanks,
Harald Gjermundrod

Hi everyone,
I've already talked to Mathias about this but I didn't bring it up in the mailing list yet. We wanted to introduce an extension point for interactive 
connections which could then be used by plugins like the remote
debugging/compiling, the batch editor, the terminal, gvid, etc.
Two implementations for this extension point would be SSH and glogin.
This would allow all plugins that use this extension point to build
interactive connections may be provided by a middleware/some other plugin. 


Cheers,
Thomas

Hi Mathias,
I am working on it right now. I have created a new package in the bundle 
and exposed the SSH tool. I will send a patch to Harald as soon as I
have a first working version with PBS.

I don't think you had this mail, it was off the mailing list:

Hi Harald,

Thank you for your quick answer,


It may be interesting to provide the functionality to submit jobs
directly to the batch service.


In fact it is just a side effect of taking advantage of the already
implemented PBSBatchService class of geclipse. My aim is to implement 
the grid model of geclipse for PBS.


This was not initially though of, thats why the class is declared
final. But if the need is there the final can be removed. The
question is, should there be an interface declared in the
IBatchService interface for job submission or should this be done by 
extending the specific implementations as you suggest. So could you
answer the following question:

Are you going to use the qsub command to submit your job, if not
which command?


Yes,  I have been looking for an implementation of a PBS client
library in java, but it doesn't exist. So I will use qsub and command 
line parsing.

Talking about parsing, some methods of the actual PBSBatchService
doesn't work on our pbs cluster (like the one to get the kernel
version). Maybe the parsing methods can be generalized I may look into 
it.
How are you going to do the translation from jdl to whatever qsub (or 
another command) may accept?


I will base my implementation on the jsdl format because it is
documentend and normalized, and I will generate pbs scripts from it. I don't know if I will be able to implement the full specifications, but 
I think it is pretty doable to translate a launching command with
arguments and implement basic data staging in PBS.


If you let me know what interface you would like I can look into it
on Thursday(I don't have access to the code right now and will be
traveling tomorrow). You could also request the following interface
as an bugzilla feature request (
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=gEclipse&bug_severit
y=enhancement ) and


Ok.


either provide a patch for an implementation or if its simple I may
do it.
I may do the work, I'll send you the patch and the new eu.geclipse.pbs pluggin as soon as I have a working version. I will not implement the 
user interface however.


Please let me know what you would prefer.

Thanks,
Harald G.


Thank you,
Romain.
