Here I will tell you how to use it while compiling use -xinstrument=datarace but wwithout using -c. and collect the experiment using $collect -r all source arguments by default the exp starts with tha.1.er check for data race using this $tha tha.1.er You will pop up with a graphical window. I think its pretty easy to work with sun thread analyzer Hai folks,

Sun studio is having sun thread analyzer which is a data race detection tool.
Here I will tell you how to use it

while compiling use -xinstrument=datarace but wwithout using -c.
and collect the experiment using
$collect -r all source arguments
by default the exp starts with tha.1.er
check for data race using this
$tha tha.1.er
You will pop up with a graphical window.

I think its pretty easy to work with sun thread analyzer

I think <a href="http://valgrind.org/" rel="nofollow">Valgrind</a> does some limited checking as well (mostly for sequential correctness, don't know if they have extended it to threads yet), but all others are not as comprehensive as the Intel solution as far as I know. @franjesus: the thread-checker works on AMD-processors just fine. I don't think it is NUMA-aware. Thanks for the instructions on installing on Ubuntu, I will make sure to try them out shortly! @bong: I know of the Sun Studio Data-Race detection tool, but have not found the time to try it out.

I just managed to install the intel thread checker under Ubuntu. I'll reproduce it here: In short: tar xzvf tcheck3.0_007cli_lin.tar.gz cd itt_tc_cl/data/ vi install-tc.sh :1399 :s/rpm -q/dpkg -s/ :wq sudo apt-get install rpm sudo touch /etc/SuSE-release sudo ./install-tc.sh --nonrpm Accept all defaults and copy the license file to /opt/intel/licenses sudo rm /etc/SuSE-release Done!

Is it NUMA-aware?
