Hundreds of connectors are being re-soldered each week, and the Titan supercomputer at Oak Ridge National Laboratory—the world’s fastest machine—could be in regular production by May, a lab official said Wednesday.
Jeff Nichols, ORNL associate lab director for computing and computational sciences, said connectors on the $100 million computer’s motherboards had too much gold, and solder was interacting with the gold on connector pins, making the solder unstable and leading to cracks.
There are about 20,000 of the pencil-sized connectors, which link central and graphic processing units, or CPUs and GPUs. Each connector has about 100 pins.
