Compiler Invocation Notes
Sun Studio compiler patches are available at http://developers.sun.com/sunstudio/downloads/patches/ss12_patches.jsp The tested configuration included patch 124867-02, 124861-04, 124863-01, 127000-01 Peak also uses "GCC for SPARC Systems", 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
The config file option 'submit' was used. Processes were bound to cores using "submit" and "pbind". A processor set was created using psrset -c 1-255 and the runspec process was placed into the set using psrset -e 1
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.
ulimit -n 1300, set the open file limit
/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 409 GB of swap space.
Platform Notes
This result is measured on a Sun SPARC Enterprise T5440 Server. Note that the Sun SPARC Enterprise T5440 and Fujitsu SPARC Enterprise T5440 are electrically equivalent.
