While technology at Wesleyan is growing by leaps and bounds, the computational capacity is growing by gigaFLOPS and now, teraFLOPS.
Not to be confused with the prehistoric pterodactyl’s beach footwear, a teraFLOP is a term used in high-performance computing to quantify the rate at which computer systems can perform arithmetic operations. TeraFLOPs can perform one trillion operations per second (S), and for scientists at Wesleyan, this means calculations can be done up to 50 times faster with the new computing cluster, installed during the summer 2013.
Even when running at full capacity, the new computer cluster outputs only 78 degrees of heat. The older systems measured 100 degrees, and require more cooling power to operate.
“The new cluster has been revolutionary in my own work,” said Francis Starr, professor of physics. “I used to run calculations that would take a month or even a year to compute, and my patience would run out. Now, I can get results in two or three days.”
In 2006, Wesleyan’s computing cluster came in around 0.5 teraflops. In the 2010 at 1.5 teraflops, and the newest cluster has a theoretical capacity of 25 to 75 teraflops, depending on the application.
“By way of comparison, my Mac laptop comes in around 0.02 teraflops, so I would need 3,500 laptops to achieve the same compute power! I think I will need a bigger backpack,” Starr said.
The new technology also is “green.” While the new machine is 100 times more powerful than the 2006 cluster, it requires half the the electrical power to operate and less cooling power to run the hardware.
The new cluster is currently used by faculty and students in chemistry, computer science, physics, biology, the social sciences and the Quantitative Analysis Center. Henk Meij, unix systems group manager and a senior consultant for the QAC, manages the facility’s operation and offers support and maintenance for any software issues. He also offers training and teaches faculty and students how to submit jobs to the scheduling system.
“Anyone on campus who needs a fast computation, ITS offers this tremendous resource which can be very beneficial to your research,” Meij said. “We can now solve real world problems in a matter of days.”
