Because I have a little problem with finding enough test subject, and surprisingly large number of people her has high end Intel CPU.
ONLY DESKTOP USERS. I have enough samples from laptops.
I wrote a small program that should test certain stuff on hyperthreaded CPUs, and I need few people who would run it.

The required steps for 4-core CPU are:
Turn off hyperthreading and run pack, and pack4C.
Turn on hyperthreading and run pack8C.
It create two html files, and I guess the first 10 lines in each file are important.
If you have only two core CPU, use pack without hyperthreading, and pack4C for test with hyperthreading.
I need 1 sandy bridge with hyperthreading, 1 sandy bridge without, and few ivy bridge both with and without hyperthreading.
Also one AMD Bulldozer, and one 6-core Vishere, and one 8-core Vishera as a control group.
Because some people don't have offline version of Java installed (and browsers didn't bother to install all libraries), there is an offline installer: http://javadl.sun.com/webapps/download/ ... leId=75261 This is for x64 windows. You can use openJava in linux (or standard Aptitude install from was it contrib?).
