The system was configured with half of the memory in each
cell assigned to local memory.
The runs used the v5.6 f90 version of the stream benchmark, with
the following changes:

compiled as follows:
f90 -o stream_d.omp +Ofaster +DD64 +extend_source +autodbl4 +noppu
-Wl,+pd,1M +Oopenmp stream.f mysecond.o
and run with the mpsched -P RR command to distribute the processes in a
round robin
fashion across the locality domains. By default each thread allocated
memory
from the local memory in each cell. Here are the outputs for each
configuration:
