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.

The words below are, in my view, inappropriate for this document. The reference to "orders of magnitude" implies that we have a metric by which we can quantify these issues. If in fact we do not have such metrics, we should not imply that we do.
