I have a problem in using Vtune.I just want to use the function of "Sampling over time view",but I don't kown how to set the VTUNE_OVER_TIME in environment since the function is disable by default.

How you set an environment variable depends on the shell that you are using, e.g.
for bash: export VTUNE_OVER_TIME=1
for tcsh: setenv VTUNE_OVER_TIME 1
I hope this helps
