GF1 - The First Grid Forum
June 16 - 19, 1999
Moffett Field, California, USA
NASA Ames Research Center
The number of Grid initiatives combined with the overlap in people,
technologies, and challenges of these early initiatives encouraged
a number of Grid researchers and managers to convene the first "Grid
Forum workshop", which was hosted by the NASA Numerical Aerospace
Simulation (NAS) and in particular the Information Power Grid (IPG)
program, held at the NASA Ames Research Center from June 16-18,
1999. Organizers expected perhaps 50 people, however attendance
was over 150 from some 50 organizations and 4 countries, clearly
indicating great interest in the concept. There was considerable
enthusiasm for the establishment of a more permanent Grid Forum.
The groundwork for that body, including the initial working group
organization and discussion, was laid at this workshop.
Description
There is increasing interest in the
use of networks not just for communication or remote data access,
but also for the coupling of computers, instruments, data archives,
etc., with each other and with humans. Some of these applications
include collaborative environments, distributed computing, computer-enhanced
instrumentation, distributed data mining, digital libraries, and
problem solving environments.
Within the scientific community, this interest has
led to new initiatives such as the NASA Information Power Grid,
NCSA Alliance National Technology Grid, NPACI metasystems, DOE Collaboratories,
DOE ASCI DISCOM, etc., as well as the establishment of focused community
forums concerned with, for example, the use of Java for high-performance
computing (Java Grande Forum), desktop access to remote resources
(DATORR), component architectures, (CCA Forum), etc.
The Grid Forum is being proposed as a means of enhancing
the effectiveness of these diverse activities by providing communication
among practitioners and, in particular, the definition of standard
infrastructure elements. For example, multiple groups (DOE2000,
NSF PACIs, NASA IPG, and probably others) are working to define
Grid information services used to discover and characterize computers,
software, networks, etc.; there would seem to be considerable value
to agreeing on standard data models and information infrastructure,
and the Grid Forum can provide a forum for that standardization
process.
The goals of this First Grid Forum Workshop are to:
- verify that there is indeed
interest in proceeding with the creation of a Grid Forum
- determine the "rules
of engagement" under which a Grid Forum should operate
- identify
and commence discussion on an initial set of topics
Agenda
Wednesday, June 16
Welcome and introduction: Bill Feireisen (10 min)
Agenda and goals: Ian Foster (20 min)
Requirements and statements of interest
The meeting started with a series of presentations
by representatives of Grid-related projects and activities. Each
speaker was asked to provide a brief overview of the activity in
question and to identify areas in which standardization and/or information
exchange are desired.
- Information Power Grid: Bill Johnston
- Alliance National Machine Room: Randy Butler
- Alliance Access Grid: Rick Stevens
- NPACI metasystems: Andrew Grimshaw
- Data-intensive applications: Reagan Moore
- NSF workshop on online instrumentation: Klara Nahrstedt
- DISCOM: Judy Beiriger
- Internet 2: Ted Hanss
- DATORR: Gregor von Laszewski
- Java Grande Forum: Geoffrey Fox
- Alliance Portal Architecture: Dennis Gannon
- DOE2000 Collaboratories: TBA
- DOE Common Component Architecture: TBA
Candidate
Grid Forum activities
Two broad-based activities have got started in the
last year that appear to be candidates for Grid Forum sponsorship
as well as a potential model for GF working groups. We heard from
leaders of these efforts.
- Grid Security Infrastructure:
Steve Tuecke (40 min)
- Grid Information Service: Brett
Didier, Steve Fitzgerald, Karen Schuchardt, Gregor von Laszewski
(40 min)

In establishing a Grid Forum, we can look to a variety
of models such as the Internet Society and Internet Engineering
Task Force (IETF), the Message Passing Interface (MPI) Forum, etc.
Choosing the correct "rules of engagement" for the Grid
Forum will be vital to its success. Hence, we heard brief summaries
of how various existing bodies work (IETF, MPI Forum, others), and
then discussed a concrete proposal for the organization of the Grid
Forum. This proposal featured an IETF-like model, in particular:
- As little formal structure
as possible!
- A goal of advancing Grids as
a whole by identifying, defining, and encouraging deployment of
common infrastructure elements
- "Rough consensus and running
code": i.e., develop standards based on experience with real
implementations
- Focused, short-term standardization
processes (e.g., what can be achieved in a year) rather than open-ended
activities
Following this, we broke into discussion groups, with
the goal of identifying topics within which initial Grid Forum activities
should be contemplated. The list of such groups will be determined
according to where there is sufficient interest, as evidenced by
someone putting an interest group and a draft list of discussion
topics together prior to the meeting. However, here are some
candidates:
- Grid Security Infrastructure
- Grid Information Service
- Resource specification / resource
reservation
- Collaborative toolkits - e.g.
CIF
- "Global shell" functions
- Standardized scheduler interface
- Resource allocation management
/ accounting / accounting records
- Monitoring/auditing message/record
functions and formats
Friday, June 18
Friday morning was spent in breakout groups, once more, plus a further
plenary session.
