One or more of the following settings may have been set. If so, the "Platform Notes" section of the report will say so; and you can read below to find out more about what these settings mean.
Power Regulator for ProLiant support (Default=HP Dynamic Power Savings Mode)
Values for this BIOS setting can be:
Adjacent Sector Prefetch (Default = Enabled):
This BIOS option allows the enabling/disabling of a processor mechanism to fetch the adjacent cache line within an 128-byte sector that contains the data needed due to a cache line miss.
In some limited cases, setting this option to Disabled may improve performance. In the majority of cases, the default value of Enabled provides better performance. Users should only disable this option after performing application benchmarking to verify improved performance in their environment.
submit= MYMASK=`printf '0x%x' \$((1<<\$SPECCOPYNUM))`; /usr/bin/taskset \$MYMASK $command
When running multiple copies of benchmarks, the SPEC config file feature submit is sometimes used to cause individual jobs to be bound to specific processors. This specific submit command is used for Linux. The description of the elements of the command are:
ulimit -s
Sets the stack size to n kbytes, or unlimited to allow the stack size to grow without limit.
]]>-unroll0, -fno-builtin -mno-ieee-fp -fomit-frame-pointer -ffunction-sections
]]>-fp
]]>-O3 (maximum speed and high-level optimizations)
-ipo (enables interprocedural optimizations across files)
-xP (generate code specialized for Intel Pentium 4 processor and compatible Intel processors with Streaming SIMD Extensions 3)
-no-prec-div (disable -prec-div) where -prec-div improves precision of FP divides (some speed impact)
-static (statically link libraries during compilation)
To override one of the options set by /fast, specify that option after the -fast option on the command line. The options set by /fast may change from release to release.
]]>These options also enable advanced data layout and code restructuring optimizations to improve memory accesses for Intel processors.
]]>The default, -mno-ieee-fp, provides better accuracy and run-time per- formance at the expense of less consistent floating-point results.
