Dear Justin and other gromacs users ,
                                                                    Thank you for your Previous reply
I  Have AMD Block Edition FX8350 Processor  Also I have Ubuntu 10.04 OS 

Using 8 MPI threads
Compiled acceleration: SSE4.1 (Gromacs could use AVX_128_FMA on this machine, which is better)

As you mailed me for the aforesaid about performance
I want to Ugrade gcc version 4.7.2
already i had version gcc 4.4.3 When I want to Upgrade
But Though  I give the following Commands

add-apt-repository ppa:ubuntu-toolchain-r/test
apt-get update

apt-get install gcc-4.7
  it has not been updated
this is confirmed When i check gcc version in terminal
