Intel Xeon Phi processor Knights Hill additional details shared

Intel today shared the latest details about the Intel Xeon Phi processor (code-named Knights Hill) that will strengthen its presence in high-performance computing (HPC).

The company will be building Intel Xeon Phi using Intel’s 10nm process technology and integrate Intel Omni-Path Fabric technology.

Knights Hill will follow the upcoming Knights Landing product, with first commercial systems based on Knights Landing expected to begin shipping next year, said Intel.

More than 50 providers are expected to offer systems built using the new processor version of Knights Landing. The committed customer deals using the Knights Landing processor represent over 100 PFLOPS of system compute, said Intel.

Intel has already announced Knights Landing deals such as the Trinity supercomputer, a project of Los Alamos and Sandia National Laboratories, and Cori supercomputer, announced by the U.S. Department of Energy’s (DOE) National Energy Research Scientific Computing (NERSC) Center.

This apart, DownUnder GeoSolutions a geosciences company, announced the deployment of current-generation Intel Xeon Phi coprocessors, and the National Supercomputing Center IT4Innovations added a new supercomputer that will become the largest Intel Xeon Phi coprocessor-based cluster in Europe.

The 44th edition of the TOP500 list noted that Intel-based systems account for 86 percent of all supercomputers and 97 percent of all new additions. In the two years since the launch of the first-generation Intel Xeon Phi products, these many-core, coprocessor-based systems represent 17 percent of the aggregated performance of all TOP500 supercomputers.

Meanwhile, Intel disclosed that the IntelOmni-Path Architecture is expected to offer 100 Gbps line speed and up to 56 percent lower switch fabric latency in medium-to-large clusters than InfiniBand alternatives.

The Intel Omni-Path Architecture will use a 48 port switch chip to deliver greater port density and system scaling compared to the current 36 port InfiniBand alternatives. Providing up to 33 percent more nodes per switch chip is expected to reduce the number of switches required.

Expected system scaling benefits include:

Up to 1.3x greater port density than InfiniBand – enabling smaller clusters to maximize single switch investments

Use up to 50 percent fewer switches than a comparable InfiniBand-based cluster of medium- to large-size

Up to 2.3x higher scaling in a two-tier fabric configuration using the same number of switches as an InfiniBand-based cluster – allowing for more cost-effective scaling for very large cluster-based systems

Intel also announced the expansion of the Intel Parallel Computing Centers, bringing the total to more than 40 centers in 13 countries working to modernize more than 70 of HPC’s community codes.

This apart, Intel expanded its Lustre software capabilities with the release of Intel Enterprise Edition for Lustre software v2.2 and Intel Foundation Edition for Lustre software. New appliances using the enhanced Intel Solutions for Lustre software are currently being offered from Dell, DataDirect Networks and Dot Hill.
