[Wien] Benchmark-Compilation options

[Dr. Emilio Orgaz]

For information;

I compiled W2K as Cesar Clazo did'it  (ifort9.0 +mkl8.0,
libgoto_itanium2_64p-r1.00)

Results for the benchmark in a ALTIX  Itanium2 @ 1.5 GHz with 4 MB in  L3
are ;

    ********************************************************

       NUMBER OF K-POINTS:           1
   ===> TOTAL CPU       TIME:   1734.1 (INIT =     21.3 + K-POINTS =
1712.9)
   > SUM OF WALL CLOCK TIMES:    169.8 (INIT =      2.2 + K-POINTS =
167.6)
      Maximum WALL clock time:    169.997846841812
      Maximum CPU time:           1734.78000000000
