STREAM results (Fujitsu SPARC M10-4S, 256 cores)

Dear Dr. McCalpin,

We have measured STREAM benchmark on "Fujitsu SPARC M10-4S".
Please update the STREAM Web site.

         System Name: Fujitsu SPARC M10-4S
            CPU Name: SPARC64 X
             CPU MHz: 3000
      CPU(s) enabled: 256 cores, 16 chips, 16 cores/chip, 2 threads/core
       Primary Cache: 64 KB I + 64 KB D on chip per core
     Secondary Cache: 24 MB I+D on chip per chip
            L3 Cache: None
         Other Cache: None
              Memory: 2 TB (128 x 16GB 2Rx4 PC3L-12800R-CL11, ECC,
                      running at 1600 MHz)
    Operating System: Oracle Solaris 11.1
            Compiler: C/C++: Version 12.3 of Oracle Solaris Studio,
                      1/13 Platform Specific Enhancement
   Compilation Flags: -fast -m64 -xopenmp -xtarget=sparc64x
                      -fma=fused -xipo=2 -xpagesize=4M -xlinkopt
                      -xvector -xprefetch_level=3 -xprefetch=latx:8.0
                      -Qoption cg -Qlp-dl=1,-Qms_pipe-prefdl=1
                      -xtypemap=integer:64
  STREAM Source Code: Fortran version (v5.6) with format changes
                      for large arrays.
         OS Settings: (/etc/system parameters) lpg_alloc_prefer=1
   Shell Environment: OMP_NUM_THREADS=512
                      SUNW_MP_PROCBIND="0-511"
                      SUNW_MP_THR_IDLE=spin
                      LD_PRELOAD=madv.so.1
                      LD_PRELOAD_64=madv.so.1
                      MADV=access_lwp
                 Run: ppgsz -o heap=256M,stack=256M,anon=256M <stream>
