title: Time Stamp Counter
body: <p>I am using time stamp counter in my C++ programme by querying the register. However, one problem I encounter is that the function to acquire the time stamp would acquire from different CPU. How could I ensure that my function would always acquire the timestamp from the same CPU or is there anyway to synchronize the CPU? By the way, my programme is running on 4 cores server in Fedora 13 64 bit.</p>
  
  <p>Thanks.</p>
