Hi John,

Please find attached STREAM results for a 256-socket SGI UV 3000
system with Haswell-EP 4S processors.

System details:
SGI UV 3000 (SSI)
256 Intel E5-4650v3 processors (12-core 2.1 GHz / 30 MB L3 cache)
Turbo mode disabled
Hyperthreading disabled
32 TB main memory (2048x16GB dual-rank DDR4-2133 RDIMMs)
SUSE Linux Enterprise Server 11 SP3 + SGI Performance Suite 1.10 for Linux
Transparent huge pages enabled in OS

Run details:
Intel compiler
Compiler flags: -O3 -ipo -xCORE-AVX2 -fno-alias -sox -nolib-inline -opt-streaming-stores always -openmp -mcmodel=medium -shared-intel

Standard STREAM Fortran source code was used, modified to handle formatting requirements of large arrays and to speed up array initialization.
The dplace tool was used to pin OpenMP threads to cpus -- 6 threads per socket, 1536 threads total. The system itself has 3072 cores.

Thanks and regards,
John Baron
