The Magnificent Mary Lou

Physics, animation, DNA, and grammar--it's all in a day's work for BYU's five supercomputers named Mary Lou. Together they daily juggle trillions of tasks, helping students and professors give form to their ideas.

Mary Lou Super Computers

She can be an intimidating presence. At the top of BYU’s computing hierarchy, Mary Lou wields phenomenal power, keeps a mind-boggling schedule, and resolves staggering problems in seconds. Her net worth easily tops $30 million, and she spends her days in a glass-walled office on the top floor of the Crabtree Technology Building, secured by two sets of code-locked doors. Yet her virtual door opens readily for any student who needs her help with high-tech research.

Mary Lou, of course, is a computer. Actually, she’s five computers. Actually, she’s five supercomputers (Mary Lou, Mary Lou 1, Mary Lou 2, Mary Lou 10, and Mary Lou X), and her office is a climate-controlled environment where she knocks tasks off her to-do list by the trillions. With the ability to process more than one teraflop—a trillion calculations per second—by herself, Mary Lou X ranks as one of the 200 most powerful computers in the world. As a group, the five machines can compute two teraflops, and to tap that power a student only needs a valid project and a faculty mentor’s support. In fact, students make up two-thirds of BYU supercomputer users, and half of those are undergraduates.

That such speedy technology contributes to undergraduate-student projects makes Ira Fulton, the donor of the supercomputers, happy. Undergraduate access is rare in the world of academic supercomputing, and free access, like that at BYU, is almost unheard of. Fulton, husband of the flesh-and-blood Mary Lou, understands the value of student exposure to supercomputers, and he wants BYU to make sure Mary Lou’s 788 processors have time in their schedules for undergraduates.

Many a student résumé has been enhanced by Mary Lou. For example, a 2002–03 animation class used Mary Lou to create a short film called Lemmings. So impressive is the final product that one animation studio, with a policy of not hiring recent graduates, grabbed four recent BYU graduates who worked on Lemmings; a fifth received three job offers in three days and is now working on the next Star Wars movie.

None of that would have happened without Mary Lou and her open-door policy.

The following sections offer an overview of Mary Lou’s portfolio—the power she possesses, the projects she facilitates, and the computing history she follows—as well as a glimpse at the Mary Lous of the future.

BYU’S SUPER POWER

Housed in more than a dozen refrigerator-sized cabinets, BYU’s five supercomputers named Mary Lou possess phenomenal power that students and professors regularly tap for learning and research.

Computing Comparsions

The Competition

According to the official supercomputer ratings (November 2003), Mary Lou X is the 177th most powerful computer in the world. Her peers include the fastest supercomputers in the country of Oman (ranked 168), Charles Schwab company (172), Dell Computer offices (176), and NASA’s Jet Propulsion Laboratory (179).

In U.S. higher education, only 18 schools have faster computers. Virginia Tech has the fastest academic computer. Also boasting top-25 campus computers are Cornell, Pennsylvania State, and the University of Utah.

Mary Lou X has more power than the top computer at the U.S. Department of the Treasury (208), BMW (226), Sprint PCS (268), and AT&T (456). She can also outrun any supercomputer in eastern Europe, South America, and Africa.

Terabyte Speed

BYU’s speediest computer, Mary Lou X, can perform 1 trillion calculations per second. That is around 1,500 times more than your computer at home, which can likely do about 700 million calculations per second. The same ratio describes the relative speeds of a cruising peregrine falcon and a creeping garden snail.

Pitcher of Water

Olympic-Sized Memory

Imagine pouring lemonade from a pitcher while soaking in a hot tub after swimming laps in an Olympic-sized swimming pool. The volume of the pool compares to Mary Lou 10’s 348 gigabytes of random-access memory (RAM). That is about 2,700 times greater than your home computer’s 128 megabytes, which is comparable to the hot tub. The pitcher in your hand represents early PCs with 256 kilobytes of RAM, about 1.36 million times less than Mary Lou 10.

Men at Work Sign

Processor Teamwork

If one fence-post installer digs 316 holes by himself, how long does it take? A long time. But if he brings along his 315 closest friends, the job goes quickly—like turning your data-heavy project over to Mary Lou 10’s 316 processors instead of sweating along with the single processor of a personal computer.

Power Users

An Arizona home builder and businessman, Ira Fulton sees his gifts as investments rather than donations. And he watches his BYU investments carefully.

In donations and grants alone, the supercomputing-center investment has generated more than 10 times its value. A year ago the presence of supercomputers helped lure to BYU a software and hardware donation valued at more than $300 million from PACE, an alliance of GM, EDS, and Sun Microsystems. The supercomputers have also enabled researchers to pull in more than $8 million in grants from sources with acronyms like NSF, NIH, and NASA, and BYU supercomputer projects have caught the attention of the National Weather Service, Pixar, and Nature magazine.

The eight projects featured here are a sampling of the work done on the supercomputers by scholars across campus.

Solomon's Temple

Ancient Temples Initiative

History and Ancient Scripture

A three-dimensional, interactive tour of Solomon’s ancient temple, created by BYU students and scholars, allows visitors to explore a building that hasn’t been seen for more than 2,500 years. Without a single stone or artifact from the original structure, researchers used biblical texts and comparative studies of art and architecture to create the model. BYU has created a similar tour of Herod’s Temple.

Analogical Language Modeling

Relying on Mary Lou’s vast memory, researchers predict language usage in the same way people learn it—with examples rather than rules.

BYU professors feed Mary Lou tens of thousands of real-life word combinations, from which they predict combinations that would be appropriate in new situations. The technique is having success predicting usage in languages that have never been described by rules.

Microwave Earth Remote Sensing

Every week NASA sends Professor David G. Long, ’82, and his students radar images of the earth from satellites and other sensors. This information is processed by the supercomputers and made available to NASA and the National Ice Center. The data shows changes in ocean winds, tropical vegetation, and polar ice, allowing a more detailed understanding of the earth’s surface.

Gas-Phase Molecular Recognition

Gas-Phase Molecular Recognition

Chemistry and Biochemistry

Using Mary Lou, researchers are calculating the shapes of molecules and learning how they fit together. “This is really neat chemistry,” says David V. Dearden, ’83, associate professor of chemistry and biochemistry. “Knowing how these molecules fit together is important for designing, purifying, and detecting more effective drugs and for eventually building molecule-sized machines and computing hardware.

Winged Walking Stick

Insect Phylogenomics

Integrative Biology

more.byu.edu/insects

In January 2003, Nature and National Geographic reported BYU’s remarkable discovery of the re-evolution of wings by certain species of walking sticks. Michael F. Whiting, ’90, an associate professor of integrative biology, and his students made the discovery when they analyzed the DNA sequences of 35 species of walking sticks, using the supercomputers to compare relationships among the insects.  computational fluid dynamics for renewable energy Chemical Engineering more.byu.edu/fluiddynamics With the help of the supercomputers, this team simulates the environments inside huge furnaces that produce electrical power, process materials in large industries, and make steam for industrial and residential use. They use complex, detailed computations to search for the root causes of problems like corrosion, pollutant emissions, and inefficient fuel conversion.

Lemmings

Lemmings, a five-minute student-created animated film, has received multiple film-festival awards since its completion in mid-2003. R. Brent Adams, associate professor of industrial design, says that without the supercomputers the lemmings would have been bald. “I don’t have to apologize to the students for the lack of tools that they really need to create a portfolio they’re proud of. I’ll never have to say ‘pretend like we’ve got real computers.

3-D Automotive Visualizations

Using top-of-the-line software and the IRA virtual reality theater, BYU students have revved up their automobile designs and plans with interactive 3-D models. Supercomputer-related software and hardware worth $313.

8 million, donated by GM, EDS, and Sun Microsystems, help students prepare to race into the workforce.

Sharper Visions

Deep in the bowels of BYU’s Crabtree Technology Building, clouds swarm as a complex model of tornado velocity vectors swirls in the air. The twister disappears before your eyes, and the next thing you know, a car floats in front of you, spinning on its axis.

No, it’s not magic. These images are made possible through the fiber-optic cables that link the SGI Onyx 2 supercomputer to BYU’s state-of-the-art virtual reality theater. Among those who benefit from its use are animation and industrial design students who model cars, boats, motors, and arctic rodents in three dimensions.

3-D Glasses

The small movie-theater-like facility seats up to 25 people, who simply slip on special polarized eyeglasses to create the 3-D effect. The theater is equipped with Dolby Digital Surround Sound and twin high-resolution projectors.

Affectionately dubbed IRA (Interactive Reality Auditorium) after Ira Fulton, who donated $1 million to build the facility, the theater adds another dimension to learning and prepares students to make real contributions in their fields.

Employees who know how to use this technology can save companies millions of dollars in design costs and time to market, says industrial design associate professor R. Brent Adams. “The ability to examine designs in three dimensions, to almost sense how a product will feel, can allow product managers to narrow down the design pool immediately without proceeding with further research and work on impractical designs.

The Supercomputer in the Palm of Your Hand

The computing capability that filled a room a decade ago now slips easily into your pocket. That trend will continue—the machines that calculate and simulate will continue to get faster, smaller, and cheaper.

“Supercomputers are predictors of what we will have on our desk or lap in 10 years,” says computer science professor Dan R. Olsen Jr., ’76. “In 10 years your laptop will be 100 times faster than it is now with 100 times more memory and 1,000 times more disk space, with no increase in cost. That is about the size of our current supercomputer.

“Every few years, some in the computer industry express concern that they are reaching the limits of silicon, that the chips simply don’t have the physical capacity to do more. But someone always finds a solution, and expressing information digitally will go forward whether it uses a circuit created on an artificial diamond surface or even one fashioned from individual atoms.

“Computing is fundamentally about information,” says Olsen, referring to the 1s and 0s—on and off switches—that form the foundation of digital computing. “You can compute with any physics that can differentiate between two states. Thus computing is quite independent of the physics used. We are a very long way from ‘hitting the wall’ in finding physics that will differentiate a 0 from a 1. The silicon chips of today were just as vague to us in 1980 as carbon nanotubes are today.

“In just a few years, BYU students will likely have constant access to wireless digital libraries, sleek interactive electronic textbooks, and live video lectures to enhance their education. Perhaps, like the students who today use the virtual reality auditorium on campus, students campuswide will participate in lectures punctuated with manipulatable 3-D models floating above the room.

As research aids, Olsen says computers of the future will be programmed to learn and evolve on their own, developing the ability to find not only the answers but also the questions. “Increasingly scientists will guide computers to discover problems,” he predicts.

But as with supercomputers today, what the computers of tomorrow will enable us to do is more significant than the machines themselves. “We’ve got a lot of new research topics as a result of the supercomputer,” says David G. Long, ’82, a professor of electrical and computer engineering. “I consider that actually more valuable than having this enormous computer to be doing it on. Having the computer has freed up our thinking and enabled us to develop whole new sets of ideas and ways to solve problems.
