  make check install


=======================
Intel compiler settings
=======================

The Intel compiler can improve performance by vectorizing certain
parts of the code on x86 architectures.

  ./configure CC=icc
  make CFLAGS="-O3 -xCORE-AVX2"

This assumes that you have a CPU which supports AVX2.
