Mario,

A "grosso modo", te paso los resultados de 2 corridas del Linpack
Benchmark, para n=1000 en el Nodo1 del cluster:

g77 -O2 -funroll-all-loops -o 1000d_g77.exe 1000d_b.f	-> Mflops = 40
	factor		solve		total	  mflops		 unit		ratio
1.700E+01  0.000E+00  1.700E+01  3.933E+01  5.085E-02  3.036E+02


pgf77 -O4 -unroll-all-loops -o 1000d_p77.exe 1000d_b.f  -> Mflops = 42
	factor		solve		total	  mflops		 unit		ratio
1.600E+01  0.000E+00  1.600E+01  4.179E+01  4.786E-02  2.857E+02

Observaciones:

1) No se hizo una corrida "estadistica", pero se los repitio "a pata"
	m-veces y, mas o menos, se mantuvieron estos valores;

2) Durante las corridas no hubo otro proceso importante segun el top
