[Pw_forum] Reading input file in MPI version (Linux cluster)

[Sergei Lisenkov]

Dear PWscf authors and users,

 I have a problem with running PWscf code on PC Linux cluster with SCALI MPI. In this implementation pw.x code cannot read input file. 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. 

Because system people cannot help me I think about changing of procedure of input. Is it possible to rewrite something in the source code that code could work such "./pw.x input" ? Or there are other solutions?

 Thanks a lot,
   Best wishes,
     Sergey
