Proposed Workshop at GGF

[Ian Foster]

A)     Workshop Title

Globus Toolkit Version 4: Status and Experiences


B)     Proposed workshop organizer names and affiliations (possibly incl. 
review committee for type 2). Be sure to identify yourself if you are a 
chair of an existing RG/WG.

Organizers: Ian Foster, Argonne National Laboratory & University of Chicago
I may recruit a co-organizer or two, but I haven't done so yet!


C)     RG/WG that will be involved (including potential RG/WGs as well as 
RG/WGs up for approval). If you are proposing a workshop without being a 
full RG, please provide a separate RG submission info, including candidate 
RG name, charter, area, chairs, BOF descriptions, etc.

This workshop will be coordinated with the OGSA-WG.


D)     Scope and Content (a paragraph or two of the workshop description to 
be put on the program.

Globus Toolkit version 4 (GT4), released on April 30 2005, represents a 
significant advance over earlier GT versions in terms of software quality, 
functionality, and standards conformance. This workshop will provide an 
opportunity for people not only to learn about GT4 but also to hear from 
groups working with it. Presentations at the workshop will focus in 
particular on experiences implementing and using the standards that 
underlie GT4 and that in many cases form the basis for ongoing discussions 
in OGSA-related working groups: the discussions of practical experiences 
with Web services standards in particular may provide a useful counterpoint 
to the often academic debates concerning the pros and cons of different 
approaches. The discussion of GT4 experiences should also be relevant to 
RGs concerned with Grid applications.

Additional details on GT4: Quality has been a major emphasis during the 18 
month development period and in particular the 6 month alpa-beta period, in 
which over 150 people participated. Functionality includes not only the 
GridFTP data movement service, GRAM job submission and management service, 
Reliable File Transfer service, Replica Location Service, Community 
Authorization Service, OGSA Data Access and Integration, and MyProxy 
services included in previous releases (although with 
multiple-order-of-magnitude improvements in scalability in several cases) 
but also new services such as a Workspace Management service (for dynamic 
accounts), Data Replication Service, Grid Teleoperation Control Protocol 
service, and an expanded set of Monitoring and Discovery services. In terms 
of standards conformance, GT4 provides probably the most full-featured 
implementation of Web services security available anywhere; a full-featured 
GridFTP implementation; and support for the WS Resource Framework and 
WS-Notification specifications in C, Java, and Python containers.



E)      Potential speakers for type one (invited) and possibly two 
workshops. Any additional info are welcome including the title of the talk, 
their abstract, etc. In fact the proposed program may be put here.

We propose a workshop of invited talks, as follows:

GT4 Introduction (90 mins) -- largely Globus Alliance members
         Overview (30 mins)
         Implementation of Web Services Standards (15)
         Performance (15)
         Future directions (15)
         Related Tools (15)
Early Experiences with GT4 (90 mins) -- members of the Globus user community
         China Grid (15)
         GridCast, Belfast (15)
         Intel (15)
         Condor-G and GriPhyN (15)
         Discussion (30)


F)      Past History of hosting a similar workshop inside or outside GGF.

I co-organized the Designing and Building Grid Services workshop, and have 
organized other meetings.


G)     Duration of workshop half day (2-3 slots incl. Breaks) or whole day 
(4-5 slots)

Half day: 2 x 90 mins

H)     Estimated # of participants (if possible)

100

I)        Publication Plans --- please indicate if you have plan to publish 
the workshop result with a certain publisher. If left out we will assume 
that the workshop product will be a GGF Informational Document.

We will prepare a brief report summarizing the content of the workshop and 
discussion.
