From: dickman@gmd.de (Peter Dickman) Subject: CONF: GODS '93: Granularity of Objects in Distributed Systems, Jul 93 Date: Wed, 7 Apr 1993 12:48:57 GMT Organization: GMD, Sankt Augustin, Germany Crossposted from news.announce.conferences Call for Papers and Participation GODS 93 Workshop on Granularity of Objects in Distributed Systems Monday 26th July 1993 In conjunction with ECOOP'93 The European Conference on Object-Oriented Programming 26-30 July 1993, Kaiserslauten, Germany The granularity of objects in a distributed system can have profound implications, affecting both the choice of algorithm for various tasks and the style of programming used. For example, ANSA-style traders may be appropriate for naming and locating long-lived coarse-grained objects (as in the OMG CORBA). If, however, objects are fine-grained and relatively short-lived, a pointer-following strategy, as used in the Emerald system, is likely to be more effective. The purpose of this one day workshop is to bring together researchers active in the field of distributed object systems, to discuss the issue of object granularity. Questions which might be addressed include, but are not limited to: Should programming languages offer one or two (or more?) distinct forms of objects aimed at different granularities? [Emerald has one, Argus has two] What are the implications for the developers of software engineering tools and methodologies? For compiler writers? Should language-level objects map directly to operating system objects or is compile-time consolidation appropriate? In either case, what granularity(ies) of object should the OS provide or be tuned for? What are the implications of object granularity for naming, location, storage, protection, garbage collection, migration, load balancing, performance monitoring, and other such issues? How does object granularity affect the failure modes and recovery strategies used in a distributed system? What concurrency control mechanisms are appropriate for given granularities of objects? Are particular models of transaction more or less appropriate or necessary for certain granularities of objects? The intention is to begin the workshop with a panel, including designers of distributed systems and/or languages, representing a range of views on the question of object granularity: contrasting the fine-grained and coarse-grained models against hybrids that support two views. Following on from this a number of papers will be presented addressing: (a) the way that granularity assumptions have influenced designs (b) the suitability of various algorithms for particular granularities ------------------------ Please note that the workshop is about distributed, rather than parallel, systems; submissions which assume a failure-free model, or discuss language-related issues that are not obviously linked to distribution, may be accepted for presentation, but only if time allows. ------------------------ On the following day ECOOP also hosts a workshop on Object-based Distributed Programming, addressing linguistic support for distribution-related aspects of programming. The two workshops require separate position papers and are organised entirely independently of each other. The organisers of both workshops will, however, endeavour to ensure that the two events do not overlap, except where this is appropriate and essential. For ObDP workshop details contact Rachid Guerraoui, guerraoui@lse.epfl.ch ------------------------ Attendence at GODS'93 will be limited to around forty people, selected by the organisers on the basis of submitted position papers. About ten papers will be presented, and four or eight panelists will be asked to describe their views; large amounts of time will be set aside for discussion and all attendees will be strongly encouraged to participate. A number of places are reserved for doctoral or masters students working in relevant fields. Such students may submit a description of their own work in place of a position paper. All position papers will be circulated in advance of the workshop and will also be made more widely available afterwards. ------------------------ GODS submissions must address one or more issues of relevance to the workshop. Position papers intended solely to secure a place at the workshop need only be 2 -- 4 pages long; those intended for presentation should be somewhat longer, say 5 -- 10 pages, but may be accepted for attendance only. Please indicate clearly whether or not your paper is for attendance only. Student authors are strongly encouraged to identify themselves as such. Authors of papers to be presented will have the opportunity to submit an expanded version of their paper. Please indicate the status of submitted material, eg distinguish ideas that are still being developed from work in progress and completed research. ------------------------ Submissions are required to be in postscript, formatted for both A4 and US paper sizes. We suggest that the text lie within an area of 15cm x 22cm. Instructions for submission, which should be by FTP or email, will be made available by anonymous FTP from ftp.diku.dk, directory pub/GODS93, as of Monday May 3rd. (NB: Denmark is in the Middle/Central European Timezone.) Each submission should have a principal author, to whom all messages will be sent; please provide email and postal addresses as well as telephone and fax numbers. A notice will be set to the principal author upon reception of every paper. We request that you notify us by email of your intent to submit a paper as soon as you have established such intent. Potential authors who cannot submit by electronic means must contact the organisers, by fax or letter, no later than Monday May 10th. Alternative arrangements will be made, but they must be ready to provide a position paper by Monday May 17th, rather than the later deadlines given below. ------------------------ Significant Dates: ================== Instructions for submission available: Monday May 3rd Preferred date for receipt of submissions: Friday May 28th Last date for submission of position papers: Friday June 4th Notice of reception of submission: Monday June 7th Notice of acceptance: Monday June 21st Camera ready version of accepted papers due: Friday July 2nd Circulation of accepted papers: from Monday July 5th Workshop: Monday July 26th ------------------------ Organisers: Peter Dickman University of Glasgow (visiting DIKU, Copenhagen) Eric Jul DIKU, University of Copenhagen For further information about GODS'93 contact: gods93@diku.dk In case of difficulties you can write to: GODS'93, c/o Eric Jul, DIKU, University of Copenhagen, Universitetsparken 1, DK-2100, Copenhagen, Denmark or fax: Eric Jul (GODS'93) at [+45] 35 32 14 01 Information about ECOOP'93 can be obtained from: ecoop@dfki.uni-kl.de ============================================================================
