Intel

Outscale’s infrastructure owns the latest generation of Intel processors: Haswell. This architecture allows for high calculating performance with a new instruction set and better memory access with DDR4 RAM.

Machine Description

Here is a description of the equipment of the machine used to test the Haswell processor:

  • 2 x Intel CPU E5-2699 v3 (Haswell) @ 2.30 GHz
    • 2 x 18 = 36 cores (Hyper Threading deactivated during our tests)
    • Turbo Boost deactivated during our tests
    • L3, L2, L1 memory caches: 45 MB, 256 kB, 32 kB
  • 64 GB DDR4 @ 2133 MHz

CPU Performance

With Haswell, Intel has launched the Fused Multiply/Add (FMA) instruction. The CPU can compute a multiplication followed by an addition on a 256-bit register, all in one cycle. And since one is never enough, Haswell combines two FMA units.
