attached are Stream results for a Superdome with:
4 cells (in a single partition)
16 cpus (fully populated)
64GB of memory (fully populated)
552MHz PA8600 cpus, 500MHz system frequency
running HP-UX 11i
compiled with fortran90 in 64 bit mode as follows:
f90 -o stream_d.mp +extend_source +autodbl4 +DA2.0W +noppu +DS2.0 +O3 -Wl,+pd,L -Wl,-aarchive +Oparallel strea
m_d.f second_wall.o
and source modified to adjust array size and put arrays in COMMON:
for 16 and 32 cpu runs:
