Hi Oxana, minutes will be available soon covering many aspects of your points. Take care, Morris

Oktober 2010 23:51 -- An: pgi-wg@ogf.org -- Betreff: Re: [Pgi-wg] PGI requirements list -- -- Thanks, Johannes! -- -- For those who could not attend, I think it's useful to know that the prioritization was made by counting -- appearances of requirements in 8 use case mappings; those that collected more than 4 counts got labelled green. -- -- Counting was done in a break before the last session, so I personally had no opportunity to digest the result -- during the meeting. Maybe others were luckier :-) -- -- I can't see why 50% is the in/out margin: it can be 66% or 75%, really. Or 33%. Depends what do we want to -- achieve: meet all reasonable requirements, or focus on those which are truly common. No requirement scored 8, by -- the way, so 5+ is not exactly 50%, actually. -- -- I must also admit I'm still confused whether the requirements are made *by* middleware providers, or *for* -- middleware providers. My impression was that it is the latter - or at least most people tried to present use -- cases, not middlewares. Meanwhile the spreadsheet rather suggests the former, having providers' names in column -- titles. -- -- The difference is obvious: e.g., when a use case needs, for example, bulk operations, it will need this feature -- to be implemented in *every* middleware, naively - because then the scientists will be able to run their tools -- across *all* middlewares, and our interoperability dream will be achieved. However, from the spreadsheet one may -- (mistakingly?) conclude that it is needed only in some middlewares, and thus didn't manage to get enough points. -- So, is our interoperability only a luxury for some users who are lucky to have applications that can be squeezed -- into our standards ? -- -- And another note from the Brussels meeting: already before Munich we discussed a possibility of grouping -- requirements from narrowly scoped, like "I need a resume after hold", to more generic ones. This was done in a -- way too generic manner on Tuesday, when e.g. one big common requirement was "Glue2". Did anyone take a snapshot -- of that table drawn by Morris? I have to repeat: I simply had no time to digest the "green" requirements to -- assess what are the high-level commonalities between them, if any. Well, Glue2 was there, yes, but I didn't have -- to write 3 use cases and map them to 173 requirements to get *this* wisdom as the bottom line ;-) -- -- I wish we had more time to discuss these things on Tuesday. -- -- Cheers, -- Oxana -- -- -- 26.10.2010 18:52, Johannes Watzl пишет: -- > Dear all, -- > -- > we are just finished with the PGI sessions here at OGF30. -- > The requirements list including a prioritization based on the use cases -- > can be found on GridForge: -- > http://forge.gridforum.org/sf/go/doc16080?nav=1 -- > -- > If you have any objections, please send a message to the list before the -- > next PGI call on Thursday, 4 November 2010. -- > -- > Best, -- > Johannes -- >
