+**//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++).
