CLIMATE IN A BOX
Narrated
by Michael Starobin
Climate and weather models are notoriously complex beasts.
It takes a small army of scientists and computer programmers a year or more to
build a model. Then they need a supercomputer fast enough to run it.
Like those models, the machines themselves can be
unfriendly. They're hot; they're expensive; they're big. But when you're trying
to model major parts of the planet's climate, you'll put up with a prima donna
to get punctilious power.
But
always in the back of your mind, a question: what if climate research had some
more accessible tools?
Like
one of these...a desktop sized supercomputer, with climate models loaded and
ready to run whenever and however a researcher needs it.

When
I develop something I can run it, I can test it immediately. I can see the
results. It increases the productivity tremendously.
NASA's
vision is to deliver a set of quality control procedures so researchers can
perfect their own research algorithms with a standardized baseline. The plan
would essentially declare a minimum standard for climate and weather research,
facilitating a rapid process of sharing and evolutionary development of new
ideas, and a rapid transition from research to operation.
Where big iron costs millions, these hot rods cost
many orders of magnitude less. Where the giant systems require special rooms
and architecture, desktops fit comfortably into ordinary equipment rooms or
even office spaces. But perhaps most compelling is how these machines deliver turnkey
systems, able to ingest data and start crunching shortly after installation. They
democratize climate research, analogous to how ordinary personal computers
democratized day to day computing tasks not too long
ago. In other words: easy.
Tsendgar Lee -- High End Computing Manager, NASA HQ
The
reason we put in a common software framework is exactly for the different
disciplines to come in and use the same interface to be able to exchange the
data, exchange the model, exchange workflow. This is
the box for everybody.
NASA
is one of the world leaders in climate model development. The Space Agency's
new GEOS-5 model already produces highly detailed, tightly calibrated output.
By facilitating heavyweight climate research on modest budgets, NASA hopes to
open the door for wide groups of scientists to pursue dramatic climate research
that might otherwise have been inaccessible. The Agency's plan essentially gives away computational models
to run on these systems, thus seeding the research ground with new opportunities
for discovery.
NASA's
software currently runs on LINUX, but as these new desktop supercomputers are
also capable of running Windows HPC, the Space Agency expects to deliver code
compiled for each operating system. The modeling tools themselves are written primarily
in Fortran 90, so the research community can expect to find themselves in
familiar territory soon after power cords plug into walls.

This
capability that's provided by such a system allows us to run models at a
reasonable resolution for development. Then, once we're satisfied with the
results we're getting on the desktop sized system we can then do production on
our very big supercomputers which are room sized
systems.
Climate
in a Box: NASA's big idea for modeling big science. You too might have access
to the whole planet...right on your desk.
