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++).
