Notes:

  • The following hardware is used for measurements:

    • Intel® Xeon® Processor E5-2699 v4: 2 twenty two-core CPUs (2.20 GHz Processor Base Frequency), Red Hat* Enterprise Linux* Server 7.2

    • Intel® Xeon® Platinum Processor 8280L: 2 twenty-eight-core CPUs (2.70 GHz Processor Base Frequency), Red Hat* Enterprise Linux* Server 7.5

  • Performance is measured over the vector length of 1000 elements.
