How relevant is Supercomputing to artists?
What kind of artist would want to go there,
either to learn or to demonstrate their
work to its audience? I admit that we
are not yet a sizable population within
the conference attendees, but would like
to make a case for an expanded participation.
Consider the areas of research that are
engaged in utilizing super computing technology:
biology and genomics, networking and telepresence
with the LambaRail, chemistry and the
rational design of drugs, reverse engineering
of the brain with studies on the limits
of human ability. Leonardos
community, including artist and scientists,
has been working in these areas in a very
serious way for a relatively long period
of time. Ray Kurzweil, the keynote speaker
at SC06, asked, "Is it possible to
understand our own brains?" As usual
he was philosophical, and he speaks to
artists as well as scientists, speaking
copiously on the exponentially accelerating
rate of progress, of which supercomputing
is a major ingredient.
Donna Cox and her wonderful team of scientific
visualization specialists (Robert Patterson
and Stuart Levy) are regulars at this
conference. Their artistry is actually
part of the scientific world far more
than of the art world. They were at the
NCSA [1] booth showing HD, stereoscopic
visualizations of galaxies and weather
systems.
But there were also artists producing
performances that operate more in the
traditional area of the performing arts
although using high performance networking
technology for both the collaborators
and the dispersed audiences. This group
is lead by Jimmy Miklavcic, a multimedia
specialist at the University of Utahs
Center for High Performance Computing,
with artistic direction by Beth Miklavcic.
The group, called Another Language
Performing Arts Company, re-presented
their fourth InterPlay performance called
Dancing on the Banks of Packet Creek
during Supercomputing. Because the
group is working over Internet2 they have
had to choose faster communication over
high resolution, employing serious video
compression. But Miklavcic has made this
work to his artistic advantage. The various
streams, coming in from Boston University,
Purdue University, the University of Maryland,
and the University of Alaska, Fairbanks,
all to the University of Utah, are mixed
by Jimmy Miklavcic and look astonishingly
like paintings with very beautifully applied
surfaces and muted colors. All of the
performers work in tandem with the sound,
which is mostly improvised, and in return
is influenced by the choices of the performers
and the visual of the main mix. It was
very impressive how the performers dealt
with the considerable, irregular delay,
known as jitter, on the still packet driven
Internet2.[2]
Miklavcic uses AccessGrid Video (Cassette)
Recorder (AGVCR) [3] to capture
and record the video streams from all
of the players. These files can them be
played back at a later time (as they were
at Supercomputing), and they can be edited
via a built-in editor. This is how they
are interwoven into such fascinating,
painting like images. The result is not
"visual music" but rather music
with image. The video was compressed with
H.261 compression, a standard video conference
method used in the Access Grid system.
The concept behind the performance is
an exploration into the "inundating
wave of digital information and non-experiential
knowledge" [4] that we are subjected
to during our digital lives. Each of the
participants created parts on their own
while thinking about the same concept.
Each site contributed at least two video
streams, with the music performed and
transmitted from the Fairbanks and Boston
locations. The performers involved in
"Packet Creek" are all quite
proficient in areas such as film, radio
broadcasting, and dance, and also have
extensive scientific and technological
backgrounds including mathematics, computer
engineering, biomedical engineering, digital
art, and 3-D animation.
My question is how would this performance
change if it were to be on the National
Lambda Rail (NLR) [5] instead of Internet2?
All of sudden the video compression would
not be necessary, and the sound would
have little delay, with a regularity that
can easily be overcome by musicians. I
believe that the whole aesthetic quality
would change dramatically.
Of course the NLR also had a great presence
at SC06. One could sit at their booth
for hours, taking in one great half hour
talk after another. Tom West, the President
and CEO of NLR, gave several introductions
to the technology throughout the conference.
We were also treated to presentations
by Larry Smarr (Calit2 at UCSD)on genomic
and ocenographic research over Optiputer,
a member of NLR, Jason Leigh (Electronic
Visualization Lab at UIC) about SAGE wall
immersive technology [6], and
Maxine Brown (UIC) on TransLight/StarLight
and TranLight/Pacific Wave [7], the complementary
efforts funded by the Nation Science Foundation
(NSF) that provides the infrastructure
connecting US, European and Pacific Rim
research and education networks. All of
this information is extremely useful to
any member of our community who desires
to be dancing on the very exciting edge
of high performance computing and networking
technology.
