[Pw_forum] installing QE

[Sanjeev Gupta]

Dear Vicky

Go in download package manager and just "type" there "mpich" , it will find
the required files, which you install. It is very easy now. Thanks to
developer for hard effort to make it easy. After installation of mpich, then
you configure as you said before in mail. it will work fine.
