Intel Gives Glimpse of Upcoming Next-Gen Xeon Phi
Intel officials at the ISC said the 14nm Knights Landing will be able to play both the processor and coprocessor roles in HPC environments.Intel officials, seven months after introducing the company's Xeon Phi coprocessors for high-performance computing systems, are highlighting the technology's success while giving the industry a glimpse of what will come in the next generation, called "Knights Landing." At the same time, the company is expanding the current Xeon Phi portfolio with two new product lines that are designed to give organizations a greater range of choices depending on workload, cost and performance. The overall thrust of Intel's message this week at the 2013 International Supercomputing Conference (ISC) in Germany is that the Xeon Phi coprocessors, more than competing graphics accelerators from Nvidia and Advanced Micro Devices, are the better option for high-performance computing (HPC) environments. "This will be a fundamental accelerator … of high-performance computing going forward," Rajeeb Hazra, vice president and general manager of Intel's Technical Computing Group, told journalists on a conference call a few days before the ISC opened.
Nvidia and AMD for the past few years have championed their GPU accelerators as the products needed for organizations that want to ramp up the performance of their supercomputers while keeping their power consumption in check. The systems can offload more highly parallel workloads from the main processor to the accelerators—which are smaller and offer many more cores than primary processors—freeing up the bigger and less energy-efficient base processor to work on the more compute-intensive tasks.
