Intel equally disclosed to DigitalSENSE Business News that the Intel Omni-Path Architecture is expected to offer 100 Gbps line speed and up to 56 per cent 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, simplifying system design and reducing infrastructure costs at every scale.
“Intel is excited about the strong market momentum and customer investment in the development of HPC systems based on current and future Intel Xeon Phi processors and high-speed fabric technology. The integration of these fundamental HPC building blocks, combined with an open standards-based programming model, will maximize HPC system performance, broaden accessibility and use, and serve as the on-ramp to exascale,” he said.
Charles Wuischpard pointed out that the expected benefits of the system scale
include up to 1.3x greater port density than InfiniBand – enabling smaller
clusters to maximize single switch investments and use up to 50 per cent fewer
switches than a comparable InfiniBand-based cluster of medium- to large-size
and 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-based systems account for 86 percent of all supercomputers and 97 percent
of all new additions, according to the 44th edition of the TOP500 list
announced today. In the two years since the introduction of the
first-generation Intel Xeon Phi product family, these many-core
coprocessor-based systems represent 17 percent of the aggregated performance of
all TOP500 supercomputers. The complete TOP500 list is available at www.top500.org.
