Re: [tsc] [msc] Candidate Draft - Landscape White Paper

Folks, TSC met today the the aim of aligning the TSR and the LS papers. We did the following. 1) Since the segmentation was the same in both papers, but in a different order, we reordered the TSR to match the current layout in the LS. This was easy, and had little impact on TSR. The segmentation probably still makes some people unhappy, but at least the two documents now agree. 2) With respect the definition of Grid, we followed Joel suggestion plus some word smithing. The result is below. We suggest that the LS document follow this approach, as it includes what they were focusing on and is very consistent with what we had intended in the TSR. ============ New TRS Text ============== The long-term vision of Grid can be summed up as follows: “Scalable distributed computing across multiple heterogeneous platforms, locations, and organizations.” The notion of distributed computing as used in this definition includes a wealth of highly complex technologies, some still the focus of research. This definition includes the degenerate case of a homogeneous HPC cluster. It also addresses operation across a wide area and possibly multiple domains of administrative control. The security, privacy, economic, and political aspects of Grids increase by orders of magnitude with the introduction of Internet scale operation. ====================================== 3) The TSC has been asked to read the LS document and provide feed back to Mark and John. Please do so. To this end, I would like to add my support to Jay's view on virtualization. I would like to see this worked into the LS document. If you can't make it fit, we might like to put in in the TSR. For reference, Jay's comments: This is pretty good but I normally make a distinction here. Virtualization is typically thought of in terms of virtualizing IT resources like computers, storage or networks. Grid takes the virtualization concept to another level and actually virtualizes the application and information resources that rely on the IT infrastructure. As you said that de-couples the applications and information from the IT infrastructure and allows the application and information to use whatever infrastructure is there. At a certain level the IT infrastructure is abstracted and made to appear homogeneous regardless of wether is dynamic (virtualized) or not. It is important to note that many Grids today are built mostly from non- virtualizaed IT resources (e.g. computers, storage and networks that are NOT virtualized) and yet the virtualization of the application and the information still allows the Grid to create an environment where resources can be pooled shared and re-purposed easily. When you combine this type of Grid virtualization and the IT resource virtualization the effects are multiplied even more. Now the static- binding is broken both between application / information and infrastructure but also between IT resources and physical hardware/ software. 4) Meanwhile, with respect to further work on the TSR, I have the pen. I will, but have no idea when, work through the public comments and either a) Make the recommended change if it seems simple enough to do without extended discussion, or b) Post a tracker for discussion wrt the next version. Then we will have a call on April 11 or 25 to agree my changes. If anyone else would like the pen for a few days PLEASE let me know and you can have it. NB The pen is currently available and the Public comments can be found here [https://forge.gridforum.org/sf/discussion/ do/listTopics/projects.ggf-editor/ discussion.info_technical_strategy_document] if anyone is interested this week. Thanks and talk later. -- Take care: Dr. David Snelling < David . Snelling . UK .

You tried to contact me

Mark, You asked about the TSC - I was snowed under at the time and then lost connectivity. Sorry I wasn't trying to be rude. Status of TSC Document: Members of the TSC are this week are (supposed to be) proposing replies to the Public Comments that we can approve on the next call (the 28th). I haven't seen any activity yet, but this mail should serve as a reminder. The one thing I know you are concerned about is the scope of our Grid Definition. I will stick to the DC across Multiple Administrative Domains, but I realize that several people have interpreted this a "Narrowing" the scope, but that is not how I meant it. It should be widening it. This we can fix. -- Take care: Dr. David Snelling < David . Snelling . UK .

TSC Action Items, but no call
by Joel Replogle 14 Mar '07

14 Mar '07

All - Unless there is strong objection, I think we should cancel the TSC call this week. Dave will be on a plane, and there's an OGSA F2F that will occupy some other TSC members. We have standing action items from the last call as follows: Because the TSC document has finished public comment, we need to address the comments in some fashion. So the action for each TSC member is to view the public comments, and respond to at least 2 of them, so we make sure that all comments get a reply. We want to get complete coverage in response to the comments, and make appropriate changes so that we can get the TS Document published in a timely manner. Attached are the minutes from the previous call. Thanks, Joel ------------------------------------------------------------------------ ----------- Joel Replogle - Manager of Standards, Open Grid Forum replogle(a)ogf.org http://www.ogf.org
