Intel

The Outscale infrastructure has the latest generation of Intel processors: Haswell. This new architecture provides improved compute performance with a new set of instructions and better memory access with DDR4 type RAM.

Description of machines

Here is the hardware description of the machine used to evaluate the Haswell processor:

  • 2 x Intel E5-2699 CPU v3 (Haswell) @ 2.30 GHz

    • 2 x 18 = 36 hearts (Hyper Threading disabled during our evaluations)

    • Turbo Boost disabled in our evaluations

    • L3, L2, L1 memory cache: 45 MB, 256 kB, 32 kB

  • 64 GB DDR4 @ 2133 MHz

CPU Performance

With Haswell, Intel inaugurates the Fused Multiply / Add (FMA) instruction. The CPU can perform a multiplication followed by an addition to 256-bit registers, all in one cycle. And because it’s never enough, Haswell combines two FMA units.
