Compiler Invocation Notes
Sun Studio 12 Update 1 pre-release build 41.1 was used.
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 1-255 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.
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.
zfs:zfs_arc_max = 0x10000000
Limits the consumption of memory by the zfs file system
The "webconsole" service was turned off using
svcadm disable webconsole
The system had 137 GB of swap space.
Platform Notes
This result was measured on a Sun SPARC Enterprise T5440. The Sun SPARC Enterprise T5440 and the Fujitsu SPARC Enterprise T5440 are electrically equivalent.
