Compiler Invocation Notes
This result was measured with pre-release build 36.0
of Sun Studio 12 Update 1
Peak also uses "GCC for SPARC Systems 4.2.1", which
combines gcc with the Sun Code Generator for SPARC
systems. It is invoked as "gcc", and accepts source
code compatible with GCC 4.2.
For more information, including support, see
http://cooltools.sunsource.net/gcc/
Submit Notes
A processor set was created using psrset -c 1-63 and the runspec process was placed into the set using psrset -e 1 The config file option 'submit' was used to select specific processors within the set, along with the pbind command.
Operating System Notes
ulimit -s 131072 was used to allow the stack to grow
up to 131072 KB (aka 128 MB). Note that saying "131072"
is preferable to "unlimited", because there is a tradeoff
between space for the stack vs. space for the heap.
/etc/system parameters
autoup=600
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=1
Set maximum percent memory for file system cache
tune_t_fsflushr=10
Controls how many seconds elapse between runs of the
page flush daemon, fsflush.
tsb_rss_factor=128
Suggests that the the size of the TSB (Translation Storage Buffer)
may be increased if it is more than 25% (128/512) full. Doing so
may reduce TSB traps, at the cost of additional kernel memory.
The "webconsole" service was turned off using
svcadm disable webconsole
The system had 68 GB of swap space.
