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
Operating System Notes
The Sun Blade 6000 was tested with 10x T6320 Modules,
each containing 1x UltraSPARC T2 chip.
The Sun Blade T6320 is supported by Solaris 10 8/07
plus a factory-installed set of patches. As tested, the
system used a 15 January 2008 pre-release build of the
patch set.
OS and test harness settings include:
- On each T6320 Module:
- The "webconsole" service was turned off using
svcadm disable webconsole
- /etc/system settings:
autoup = 600
set bufhwm_pct=1
set segmap_percent=2
set tsb_rss_factor=128
tune_t_fsflushr = 10
- Process settings:
ulimit -s 131072
- The "submit" feature was used with a perl procedure, which did
arithmetic to derive processor numbers from the SPEC copy number
Additional details about the above points be found in the "Platform
Settings" section of the associated flags file.
