[Pw_forum] new question: Solved: mpi compile errer?

[Tianying Yan]

Dear pwscfers,

The compiled MPI excutable only runs on 2 CPUs within the same node, but can not setup commnication across the nodes. Do I again miss something? Thank you very much!

Best regards, Tianying

Problem solved by modifying Makefile to include mpif.h in path or copy mpif.h into include subdirectory under pwscf root directory. Hopefully such a solution is the correct one. As I am running one test job from examples and give the same result as the one in reference.

Dear pwscf user,

I am just new in this list and I have a question about compiling pwscf on a linux64 cluser.

/configure ARCH=linux64
make all

However, the compilation is failed for the para.f90 subroutine in PW sub-directory. I believe the MPI environment is correctly set up, but what is the problem? Any hint would be grateful.

The error message looks as
