FYI - DRMAA is well-known in India and China. Just wow ... Is there any existing DRMAA Java implementation that does NOT rely on JNI ? From what I know, the answer is no.

Hi all,
Like Andre said, it seems there is no full java implementation of DRMAA, and the one for your targeted system also relies on JNI to wrap the C API.
Andre, is the Java wrapper for DRMAA you are mentioning independent from any middleware? If so, do you have some link to this project?
Giuseppe, please keep us informed about your direction for supporting the DRMAA interfaces.
Best regards, Sylvain

Dear Andre, of course we are quite interested in this SAGA/DRMAA interfaces. Could you send us URL to documentaton and/or code?
Perhaps we could find some resources to work on this.
About India DRMAAv.1 is perfectly OK. For China we can try to interest them on v.1 and see if they are available to work on v.2.
Thank you Best regards Giuseppe Andronico

Dear Andre, Sylvain,
the guy working on GOS adapter for JSAGA in Beijing released the adapter and we are going to test it in next days, during the EPIKH school in Beijing, with the support of Diego that already integrated the released code in our Science Gateway.
Sounds like progress :-) Good luck with the testing!
Also I tried to understand some more about the DRMAA adapter for SAGA/JSAGA, but it looks like there were some studies but no implementation. Also I tried to contact Peter Troger by email, but the mail address in his business card is not recognized any more.
Please use this one: "Peter Tröger"<peter@troeger.eu>
FWIW, there is in fact a DRMAA adaptor for SAGA-C++, which uses the varius DRMAA libraries available for schedulers (PBS, SGE, Condor, ...). We plan to also develop a DRMAA adaptor for our new python implementation (there is a DRMAA python binding in pypi) -- but that is not yet available. IIRC, there is also a Java wrapper for DRMAA, which can use the very same drmaa libs. OTOH, I don't think there is a clean Java stack for DRMAA.
The above is all about DRMAAv.1 -- DRMAAv.2 was recently published, and implementations are slowly emerging. Just mentioning... :-)
DRMAA is important for us for the infrastructure in India and could be some interest is in China.
Interesting! Please let us know if you need more information about DRMAA / SAGA...
Best, Andre.
