Hi, If your error message really indicates that fftw is the problem, I'd like to guess that the way you linked your espresso programs is the issue. You may linked the programs with fftw dynamically, while your fftw is only installed on your fronted, so that when the program is distributed to the compute nodes, the program could not find where the .so file is at these nodes.
You may need to install fftw either on every compute nodes, or under a network shared directory, or link quantum espresso with fftw statically. As you didn't show us your error message, the above is just a guess.

After the make all command i get following error. make[2]: *** [pw.x] Error 1 make[2]: Leaving directory `/c9gpfs/c9scratch/user/qe/espresso-5.1/PW/src' make[1]: *** [pw] Error 1 make[1]: Leaving directory `/c9gpfs/c9scratch/user/qe/espresso-5.1/PW' make: *** [pw] Error 1 It seems the some FFTW lib problem and i am very new to all this. Any help will be greatly appreciated. Thanks Ajanta Research Scholar Harish Chandra Research Institute, Allahabad,India
