That looks good. Out of the "summary, please fix" items, the main one is:
* consider adding /users/PAS1316/prateeksasan/linux_openmp_64 to your PATH

So in your .bashrc file, add something like:

export PATH=$PATH:$HOME/linux_openmp_64

Then you can open a new terminal, or just source that .bashrc file.

Note that we have a linux_centos_7_64 package that might be slightly more appropriate for your system, that what you have seems to be working fine.
