Operating System Notes
Processes were bound to cores using "submit" and "pbind" except
for peak runs of 403.gcc, 456.hmmer, and 483.xalancbmk.
"ulimit -s unlimited"
Allows stack to grow until system limit.
/etc/system parameters
tune_t_fsflushr=3
Controls how many seconds elapse between runs of the
page flush daemon, fsflush.
autoup=1200
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
ts_dispatch_extended=0
Selects default dispatch table, rather than large server table
Platform Notes
The tested system had 18 system boards. The first 17 system boards were equipped with 16GB of memory; the last system board had 32GB. All memory was 8-way interleaved.
