hi
You can register a account on http://www.minix3.ucsc.edu/wikis/minix3/
and upload you package here. chinaunix don't support tar.bz2 package.

One question: Since nbench is a cpu benchmark, shouldn't you have used
-O0 (no optimization) instead? Using -O2 could potentially skew
results as it would optimize the code which can work better on a
particular (class of) processor, but not much better on other
processors. Just a thought. Every benchmark I've ran before, I've
compiled with -O0 to avoid any skewing.

Hi,

It’s a real question once confusing me. Benchmark programs are built as a representing of currently famous programs to evaluate performances, and it should be compiled the way users compile programs. Using –O0 may fair for all kinds of CPUs on which benchmarks are running, but in realistic lots of programs are compiled with –O2 or –O3. Meanwhile, I find that nbench’s default Makefile either using –O3 or –O2. So I used –O2, but there is a compromise choice, we can provide two ways “base’ and “peak” to compile nbench like SPECCPU benchmark does.
