     Athlon MP 1800 (2 cpu) Tyan Tiger MP, 1 GB DDR memory
     Linux 2.4.18

     Compiled with:

     pgf77 -mp -fast -tp athlon -Minline -Mvect=assoc,prefetch,cachesize:327680 \
      -Mcache_align second_wall.o stream_d.f

    ----------------------------------------------
     Double precision appears to have 16 digits of accuracy
     Assuming 8 bytes per DOUBLE PRECISION word
    ----------------------------------------------
     Array size = 10000000
     Offset = 0
     The total memory requirement is 228 MB
     You are running each test 10 times
     --
     The *best* time for each test is used
     *EXCLUDING* the first and last iterations
     ----------------------------------------------------
     Your clock granularity appears to be less than one microsecond
     Your clock granularity/precision appears to be 1 microseconds
