Joel and Guy, Thank you so much for inserting the session! see you at Oxford soon! -- HIDEMOTO NAKADA, Ph.D, AIST, Japan On Thu, Feb 23, 2012 at 9:29 AM, Hidemoto Nakada <hide-nakada@aist.go.jp> wrote:
Joel and Guy,
thank you for your hard work for OGF34.
we (GridRPC WG) thought that we requested GridRPC group session on Tuesday by the attached e-mail, but it did not appear in the schedule.
Could you please add it on the schedule? Fortunately, Tuesday morning, which is convenient for us, seminar room seems to be available.
thank you in advance.

Dear Daniel and Joel,
The current text of the Grid-RPC is outdated. I will sent a some upgrade as soon as possible.
About the next session it could be fruitful to give more information. Is it possible to have a session on Tuesday ?
Text for the next Grid-RPC session : ------------------------------------------------
Join the next Grid-RPC session and come with your data management use case ...
In september 2011, the Open Grid Forum standardized the document "Data Management API within the GridRPC" [1] which discribes an optional API that extends the GridRPC standard [2]. Used in a GridRPC middleware, it provides a minimal set of functions to handle a large set of data operations among which: movements, replications, migrations, data prefetch and persistency.
After a few remarks on the GridRPC DM API, we'll present a basic implementation that we have integrated in two different middleware, respectively DIET [3] and NINF [4]. We have conducted several experiments, showing very high benefits that a Grid user can expect 1) in terms of resource usage compared to the current GridRPC context since useless transfers are avoided; 2) in terms of reducing the completion time of an application to obtain results the soonest (data can be prefetched and replicated, hence letting calculus to be submitted really soon in a workflow analysis in addition to the possible overlap between computations and communications); 3) in terms of code portability, since we show with these examples that at last the same GridRPC code can be compiled and executed within two different GridRPC middleware which implements the GridRPC data management API; 4) finally we thus obtain middleware interoperability without any explicit glue as generally done like in [5]: we show as a proof of concept that resources dispatched across different administrative domains can be used altogether without the underlying distributed data management systems having any knowledge of the workflow and/or computing resources: computational servers of DIET and NINF transparently collaborate to the same calculus by sharing GridRPC data!

Hi Peter, Eddy, and Andre,
Can you take a quick look at http://www.ogf.org/gf/group_info/areasgroups.php?area_id=5 and see what is out of date and what needs to be changed?
Please email Joel the changes that should be made, and copy Wolfgang and me.
Thanks, Dan
