# March 2013
#
# ... 8x aggregate factor AVX code path is using reduction algorithm
# suggested by Shay Gueron[1]. Even though contemporary AVX-capable
# CPUs such as Sandy and Ivy Bridge can execute it, the code performs
# sub-optimally in comparison to above mentioned version. But thanks
# to Ilya Albrekht and Max Locktyukhin of Intel Corp. we know that
# it will perform better on upcoming Haswell processor. [Exact
# performance numbers to be added at launch.]
