Service Discovery
by Fisher, SM (Steve) 21 Aug '07

21 Aug '07

Hi, I attach a first draft of the proposed service discovery SAGA API extension following very closely my presentation at the last GGF. Once I have write access to CVS I will check the source files in. We have a prototpye implementation which does not make use of a proper adapter mechanism yet - however we plan to use the SAGA adapter style for the C++. The C++ prototpye is almost complete for the BDII (LDAP) information system and the R-GMA one is not far behind. The performance is good - we can show it at Manchester. We would appreciate any comments - especially identifying those areas where we are not doing things "the SAGA way". Incidentally we were surprised that we are only expected to use one name space for the implementation - why are sub-namespaces not permitted - especially for the API extensions? For the Java implementation are we expected to use lower case class names and underscore separated method names? Steve

drmaa public comments

You may want to have a look at the DRMAA mailing list archive from this month: http://www.ogf.org/pipermail/drmaa-wg/2007-May/thread.html The DRMAA group got a number of comments in respect to their interop document (I believe), which raise several issues which are also interesting for SAGA. In general, SAGA seems already to address all of these issues. Nice :-) Cheers, Andre. -- "XML is like violence: if it does not help, use more."

Question about saga::attribute and saga::async
by Ceriel JH Jacobs 01 May '07

01 May '07

Hi, I noticed that version 1.0 RC 5 of the SAGA document specifies that the saga::attribute interface now implements the saga::async interface. I assume that this means that there must be task- and async versions of the saga::attribute methods. But this also means that several other classes now must implement saga::async (because they implement saga::attribute). For instance, the class "metric" in package saga.monitoring, should that now have async and task versions of the add_callback, remove_callback and fire methods? I guess not, but since it now implements saga::async, should it? Ceriel Jacobs

Fwd (newby@arsc.edu): [gfsg] Documents in initial GFSG review
by Andre Merzky 01 May '07

01 May '07

Hi Folx, the JSDL group submitted two JSDL extensions into the recommendation track. They are not yet in public comment, but we should cross check the core API against these docs, before final publication of the core. Cheers, Andre. ----- Forwarded message from Greg Newby <newby(a)arsc.edu> ----- > Title: JSDL HPC Profile Application Extension (Version 1.0) > > Tracker URL: http://forge.gridforum.org/sf/go/artf5852?nav=1 > > Direct download: http://forge.gridforum.org/sf/sfmain/do/downloadAttachment/projects.ggf-edi… > > > Title: JSDL SPMD Application Extension 1.0 > > Tracker URL: http://forge.gridforum.org/sf/go/artf5840?nav=1 > > Direct download: http://forge.gridforum.org/sf/sfmain/do/downloadAttachment/projects.ggf-edi… -- "XML is like violence: if it does not help, use more."
