I am using ubuntu 11.1 (64 bit). The Ubuntu normally runs when I
dont run the Gromacs program. i.e there is not heating problem.
But the CPU is excessive heating (82 degree) when I run the
gromacs. <br>

There are various "stress test" programs you can get if you Google
around. I expect these will produce the same symptoms.<br>

I'd say this is evidence that you don't have sufficient cooling.<br>

If things are installed correctly. For example, cheap thermal paste
between the CPU and heat sink can cause these symptoms.<br>

Get more cooling. Maybe lower the clock speed (if possible). Run a
less efficient MD code!<br>
