you have simply to run the pw.x executable in this way:
pw.x -input input_file > output_file .or.
pw.x -inp input_file > output_file .or.
pw.x -in input_file > output_file
Let me know if it doesn't work.

I asked of system people of this cluster but they could not suggest anything. I tried a different input keys such "-stdin" but it does't helps. It seems that in such mpi mode system cannot read the input file using "<" command. But other programs requested input file without such sign (i.e. mpirun -np 4 ./a.x input ) does work.
