      1 checktsc is a user space program that checks TSC synchronization
      2 between pairs of CPUs on an SMP system using a technique borrowed
      3 from the Linux 2.6.18 kernel.
      4 
      5 The test passes if all TSCs are within +/- "threshold" clock cycles
      6 of each other. The default value of "threshold" is 500 clock cycles
      7 and can be changed using the --threshold option.
      8 
      9 Default behaviour is to check all of the CPUs on a system and to
     10 report the observed difference in TSC values between each pair of CPUs.
     11 The --cpus option can be used to specify a subset of the CPUs to test.
     12 
     13 When run with the --silent option the test produces no output (other
     14 than for catastrophic errors) and success or failure is indicated by
     15 a 0 or 1 exit status from the program.
