Operating System Notes
Environment Variable Settings:
The maximum number of threads a program can create was set with:
OMP_NUM_THREADS=64
Program threads were bound to processors with:
SUNW_MP_PROCBIND=" 1 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34
36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70
72 74 76 78 80 82 84 86 88 90 92 94 96 98 100 102 104
104 106 108 110 112 114 116 118 120 122 124 126 "
Behavior of parallel threads was set with:
SUNW_MP_THR_IDLE=SPIN
SPIN specifies that an idle thread should spin while waiting at barrier
or waiting for new parallel regions to work on.
System Tunables (/etc/system parameters):
tune_t_fsflushr=10
Controls how many seconds elapse between runs of the
page flush daemon, fsflush.
autoup=300
Causes pages older than the listed number of seconds to
be written by fsflush.
bufhwm=3000
Memory byte limit for caching I/O buffers
segmap_percent=3
Set maximum percent memory for file system cache
lpg_alloc_prefer=1
Set lgroup page allocation to strongly prefer local pages
Other System Settings:
The webconsole service was turned off using
svcadm disable webconsole
Platform Notes
Memory is 8-way interleaved by filling all slots with the same capacity DIMMs. This result is measured on a Sun SPARC Enterprise M8000 Server. Note that the Sun SPARC Enterprise M8000 and Fujitsu SPARC Enterprise M8000 are electrically equivalent.
