 +**//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++).
