RuleML-2008: Deadline Extension
by Adrian Paschke 12 Sep '08

12 Sep '08

[ our apologies should you receive this message more than one time ] ===================================================================== Due to a number of requests we have to decided to extend the submission deadline by 2 weeks. NEW deadline for paper/demo submission: June 16 ===================================================================== 2008 International RuleML Symposium on Rule Interchange and Applications (RuleML-2008) October 30-31, 2008, Orlando, Florida http://2008.ruleml.org -------------------------------------------------------------------- RuleML-2008 Highlights: - Keynote speakers: * Michael Kifer (State University of New York at Stony Brook, USA), on "Rule Interchange Format: Not Just Syntax". Joint keynote between RuleML-2008 and RR2008. * David Luckham (Stanford University, USA) on complex event processing. * Paul Haley (Haley Ltd) on business rules. * Benjamin Grosof (Vulcan Inc, USA) on the SILK KRR system of the HALO project. (Details at: http://2008.ruleml.org/keynote.php ) - Joint Lunch Panel with the Business Rules Forum about "Rules on the Web" - RuleML-2008 Challenge with prestigious prices (Details at: http://2008.ruleml.org/challenge.php ) (Submissions at: http://ruleml-challenge.cs.nccu.edu.tw/ ) - Lightning talks / Highlight talks Accepted papers will be published in Springer LNCS proceedings and a journal special issue (IEEE TKDE pending) is forthcoming. PRESS RELEASES: http://www.targetwire.com/vpo/rm/ -------------------------------------------------------------------- Call for Papers Collocated with the 11th International Business Rules Forum, the 2008 International Symposium on Rule Interchange and Applications (RuleML-2008) is the second symposium (after last year's highly successful RuleML-2007 - http://2007.ruleml.org/) devoted to work on practical distributed rule technologies and rule-based applications which need language standards for rules operating in the context of, e.g., the Semantic Web, Intelligent Multi- Agent Systems, Event-Driven Architectures and Service-Oriented Computing Applications. The RuleML symposium is a new kind of event where the Web Rules and Logic community joins the established, practically oriented Forum of the Business Rules community (http://www.businessrulesforum.com) to help cross- fertilizing between Web and Business Logic technology. The goal of RuleML-2008 is to bring together rule system providers, representatives of, and participants in, rule standardization efforts (e.g., SBVR, RuleML, RIF, PRR, CL) and open source rules communities (e.g., jBoss Rules, CLIPS/Jess, Prova, OO jDrew, Mandarax, XSB, XQuery), practitioners and technical experts, developers, users, and researchers. They will be offered an exciting venue to exchange new ideas, practical developments and experiences on issues pertinent to the interchange and application of rules in open distributed environments such as the Web. The Symposium gives emphasis on practical issues such as technical contributions and show case demonstrations of effective, practical, deployable rule-based technologies, rule interchange formats and applications as well as discussions of lessons learned that have to be taken into account when employing rule-based technologies in distributed, (partially) open, heterogeneous environments. We also welcome groundwork that helps to build an effective, practical, and deployable rule standard, improve rule technology, provide better understanding of the integration and interchange of rules, and make the current generation of rule engines and rule technology more usable for advanced Web and Service Oriented Architectures. More details in: http://2008.ruleml.org/cfp.pdf -------------------------------------------------------------------- RuleML-2008 Challenge The RuleML-2008 Challenge is one of the highlights of RuleML-2008. It addresses the system demonstration for practical use of rule technologies in distributed and/or Web-based environments. The focus of the challenge is on rule technologies (including rule languages and engines), interoperation and interchange. The challenge offers participants the chance to demonstrate their commercial and open source tools, use cases, and applications. Prizes will be awarded to the two best applications. All accepted demos will be presented in a special Challenge Session.

DRMAA test suite moved
by Peter Tröger 29 Aug '08

29 Aug '08

Dear all, the OGF folks recently managed to create a Subversion repository for us on GridForge. The DRMAA test suite is therefore no longer part of the DRMAA condor sources, but separately located here: http://forge.gridforum.org/sf/go/projects.drmaa-wg/scm.drmaa_testsuite The links on our home page are corrected. I also fixed the Windows support - the test suite now builds with Visual Studio 2005. I tested everything with the latest Condor versions for Linux and Windows. Maybe somebody can do that also for SGE. Best regards, Peter.

Re-launch of www.drmaa.org
by Peter Tröger 20 Aug '08

20 Aug '08

Dear all, for the last two years, the drmaa.org web page was operated as a Wiki. This enabled everybody to contribute new content, which leaded (beside other things) to an impressive list of use cases. However, the increased (and improved) Wiki spam attacks in the past enforced us to spend more time with administration than with standardization. The co-chairs therefore decided run the home page in the "plain-old" style again. If you have comments, corrections or edition for the home page, please address me directly or contact the DRMAA mailing list. I hope this will be as fast as the Wiki editing ;-) Thanks, Peter.

OK. I totally agree -- that does make sense (besides the fact that there's no equivalent of wifaborted in POSIX). I'm curious about other's opinions, especially Andreas' as he will probably know the details of SGE implementation. When we agree on the consensus, I'll have to look into our LSF and PBS implementations to have this checked/fixed. As far as I remember, they're behaving like SGE, i.e. aborted = true for all terminated jobs whatever their state was. P.S. I though it'd be appropriate to move this discussion back to drmaa-wg(a)ogf.org -- Piotr Domagalski

Hi Hrabri, On Wed, Aug 6, 2008 at 11:24 PM, Rajic, Hrabri <hrabri.rajic(a)intel.com> wrote: > It seems that the SGE people are on vacation ( I am starting mine tomorrow ...). Yes, apparently. I'm starting mine on Friday ;-) The thing is that I'm rather confused about this drmaa_wifaborted stuff and have no idea whether it's just something that should have been changed long time ago in the specification or the SGE implementation is buggy. As a matter of fact, as I've been involved (at least partly) in implementations for LSF, PBS and did some fixes for Condor, I can tell that most implementations also behave just like SGE, i.e. drmaa_wifaborted = true if job was terminated, whatever the actual state. But please correct me if I'm wrong. I haven't seen the source codes for quite a long time. Another question arises if the specification is actually how it was meant to be. What is the output of wifexited, wifsignalled, wifaborted for job that was terminated during execution? I have always assumed that aborted = true. But if we assume that aborted = false in this case (because it was terminated after having entered the running state as spec says) then should it be signaled = true? -- Piotr Domagalski

Some thoughts on drmaa_wifaborted vs. DRMAA spec
by Piotr Domagalski 02 Aug '08

02 Aug '08

(had some subscription problems, reposting it) Hi all! According to the spec: drmaa_wifaborted: Evaluates into 'aborted', a non-zero value if 'stat' was returned for a job that ended before entering the running state. so aborted = true IFF the job was deleted before getting into DRMAA_PS_RUNNING? If so, then it seems that SGE's implementation is buggy, because it sets aborted for jobs terminated after having entered the running state. On the other hand [1], if drmaa_wifaborted() works this way and drmaa_wifexited(): Evaluates into 'exited' a non-zero value if stat was returned for a job that either failed after running or finished after running (see section 2.6). More detailed diagnosis can be provided by means of drmaa_wexitstatus(). Then what should I get when the job was terminated (by DRMAA) within running state? aborted = false, exited = true? What about exit status then? [1] I'm asking this question, because I thought for a long time that this SGE's behavior was according to the specification. -- Piotr Domagalski
