Avinash Sodani, Chief Architect 'Knights Landing' Xeon-Phi Processor at Intel Corporation

摘要

The demand for high performance will continue to skyrocket in the future fueled by the drive to solve the challenging problems in science and to provide the horsepower needed to support the compute-hungry use cases that are emerging in consumer and commercial space. Exploiting parallelism will be crucial in achieving the massive amounts of performance required to solve these problems. This talk will present the new Xeon Phi Processor, called Knights landing, which is architected to provide huge amounts of parallelism in a manner that is accessible with general purpose programming. The talk will provide insight into the important architecture features of the processor and explain their implications on software. It will provide the inside story on the various architecture decisions made on Knights Landing - why we architected the processor the way we did. It will show measured performance numbers from the Knights Landing silicon on range of workloads. The talk will conclude with showing the historical trends in architecture and what they mean for software as we extend the trends into the future.
