Most of the tests work, but a few, like super-pi and memory-bandwidth won't run on my system (Arch 64 ).

The errors I see are:

./memory-bandwidth: line 5: ./bandwidth: No such file or directory

./super_pi: line 1: ./pi: No such file or directory

Both work here on Ubuntu x86_64...

Must be an Arch x86_64 issue? Can you run: phoronix-test-suite force-install super-pi and then try again? Or post the output if anything else is shown.

I guess just missing build-dep.

Well, after installing the lib32 c libraries, super-pi works...but only one core gets used.........oh well. memory-bandwidth works as well.

Most of the time when I run benchmarks on either x86 or x86_64, more core #2 is used 100% and my core #1 is almost always 52%. I am not sure why. I asked someone once and they just said that core #1 is faster or vice versa.
