The runs used the v5.6 f90 version of the stream benchmark, with the
following changes:
96,97c96,97
< INTEGER n,offset,ndim,ntimes
< PARAMETER (n=2000000,offset=0,ndim=n+offset,ntimes=10)
---
> INTEGER*8 n,offset,ndim,ntimes
> PARAMETER (n=32002032,offset=0,ndim=n+offset,ntimes=10)
106c106
< INTEGER bytes(4)
---
> INTEGER*8 bytes(4)

< 9020 FORMAT (1x,a,i4,a)
---
> 9020 FORMAT (1x,a,i6,a)
compiled as follows:
f90 -o stream_d.uni +Ofaster +DSitanium2 +DD64 +extend_source
+autodbl4 +noppu -Wl,+pd,64M +Onoopenmp stream.uni.f mysecond.o
Here is the output:
stream_d.uni
