1 The reference Machine

The reference machine is my personal computer:

• Processor: Intel(R) Core(TM) i5-4670 CPU @ 3.40GHz, 4 cores.
• RAM: 8 GB.
• System: Ubuntu 18-10.
• g++: gcc version 8.2.0 (Ubuntu 8.2.0-7ubuntu1)
• Julia: Version 1.0.1 (2018-09-29)
• Python: Python 3.6.7 (default, Oct 22 2018, 11:32:17).
• Pythran: version 0.9.1post0
• Numba: numba-0.42.1

Note that the processor architecture is Haswell ,so it supports AVX2 and FMA3 instructions, which is important for some benchmarks, at least for C++ (C++ programs are compiled with -m arch=native, idem for Pythran).
