America’s Titan Supercomputer is the fastest in the world

by Laura Domela

Cray’s Titan supercomputer has snatched the title of world’s fastest from the National Nuclear Security Administration’s Sequoia—and it’s cray fast, as you might expect.

Powered by a mixture of CPUs and GPUs, Titan is home to 18,688 nodes, each of which contains an AMD 16-core Opteron and a NVIDIA Tesla K20X GPU accelerator. All told, that’s a whopping 560,640 processors, which are capable of 17.59 quadrillion operations per second. For perspective, Sequoia snatched the top spot back in June with a mere 16.32 quadrillion.

Quickly and accurately identify inter-domain leakage issues in IC designs

Sponsored by Siemens Digital Industries Software

Power domain leakage is a major IC reliability issue, often missed by traditional tools. This white paper describes challenges of identifying leakage, types of false results, and presents Siemens EDA’s Insight Analyzer. The tool proactively finds true leakage paths, filters out false positives, and helps circuit designers quickly fix risks—enabling more robust, reliable chip designs. With detailed, context-aware analysis, designers save time and improve silicon quality.
