Harvard Recruiting PC Power to Find Better Solar-Panel Materials - The Way It Works (
Page 2 of 2 )
The way this all works: Those interested register on the World Community Grid
and download the 40MB bit of screen-saver-like software that allows the project
to tap into the processor. After it is installed, a model of a type of molecule
is then sent to the computer; when the screen saver comes on, the software
automatically runs an analysis on the model to determine if it has the
properties needed to be included in the construction of the polymer plastic.
Millions of molecules need to be analyzed—one at a time. That's why it's so
time-consuming to do it in one location.
"When you're working on the machine, none of the power is used [for the
project]," Aspuru-Guzik said. "It's only when the machine is idle
that the software turns on and starts the calculations."
Project Can Cut Research Time from 22 to 2 Years
Using volunteers' computers in the grid to run these numerous calculations can
shorten a project that would normally take about 20 to 22 years to just two
years, Aspuru-Guzik said.
The IBM World Community Grid currently has
about 1 million computers linked to it. IBM
created the network a couple of years ago; it might eventually be considered to
be among the top 10 most powerful supercomputers in the world, thanks to its
sheer size and scope.
IBM, naturally, includes security software
to protect the participants' computers.
"It's a way for people that have computers to do some good for the
world," IBM engineer Joe Jasinski said.
Aspuru-Guzik said that about seven volunteers signed
up on the first day. "We hadn't even announced it yet," he said.
The Clean Energy Project is the
11th project to run on the World Community Grid and is one of six active
projects currently running.
"We are not asking people to change their habits when using their
computer," IBM Vice President of Global
Community Initiatives Robin Willner told me. "We've packaged up these
services into a mashup of sorts, and it's very safe and secure. And the
benefits to the user are wonderful."
