**//HYBRED MONTECARLO EVOLUTION (CHROMA)//** 

The timing here reported refer to the Hybrid-Montecarlo simulation 
of the Pure Gauge SU(3) Theory using the publicly available  
USQCD collaboration "chroma" library 
(http://usqcd.jlab.org/usqcd-docs/chroma/)

the timed simulation are for 2000 sweep on a lattice of size 32x32x32x4 
using hybrid montecarlo evolution of pure QCD (Nc=3)

The compilation are for single thread MPI parallelization performed using
the locally available gcc compiler suite (C + C++).
