Tools' presentation on "Grid
Computing - An Introduction" (pps - 81K) given
to the ESIP Federation during its 2005 Winter Conference in Washington
D.C., January 4-6 2005 by our Chief Scientist, Richard Troy.
Scientist, Richard Troy, has provided the following commentary regarding
the Earth Science Information Partner Federation (ESIP) was preparing
its Winter 2005 symposia, which inclined a special "Grid track,"
it was felt that as the only 'Grid provider' among the Federation's
members, I should give a talk to serve as an introduction to Grid technologies
and compare and contrast these technologies with Science Tools' approach.
But due to time constraints, I was given a half-hour at the end of the
half hour is hardly enough time, so I summarized greatly and this led
to some fairly strong assertive statements by me about the state of
Grid technology today. I knew there would be"Grid practitioners"
in the audience, so I anticipated there'd be some howlers in my talk
and therefore made the talk even shorter so we could entertain questions
and discussion. I also had to consider that I spend my time mostly working
with our own technologies and haven't ever tried to build a Grid using
GGF derived tools, so I had to consider the possibility that I'd missed
well-known Peter Fox of UCAR gave a talk earlier in the day about his
multi-year trek creating the Earth System Grid using the Global Grid
Forum's collective offerings, and I was gratified that his war stories
seemed to fit well with what I would say later in the day.
talk was very well attended with about 25 in the audience, including
Peter. I got through the material in only 17 minutes and opened the
floor for discussion and was quite surprised that when I asked the group
what they thought, they said that I'd done a great job of summarizing
the situation and that "nobody would disagree with you about the
current state of Grid technologies." As my view was rather pessimistic
about what you can do with other Grid tools, I pushed harder to flesh
out anything I'd said that was over the top or just wrong, but to my
satisfaction, the audience felt I'd nailed it."
