Yambo 4.2.1, ompi_mpi_comm_world error

[Daniele Varsano]

Dear Fabio,
set FC to ifort and not mpiifort.

Dear Daniele,

I changed it, FC = ifort

Code: Select all

MPIFC='mpif90' CPP='icc -E' CC='icc' MPICC='mpiicc'  F77='ifort' FC='ifort'

I get the error:

checking for dummy main to link with Fortran 77 libraries... unknown
configure: error: in `/home/fabiof/bin/yambo-4.2.1':
configure: error: linking to Fortran libraries from C fails

When I check the config log, I see FC='mpif90' and F77='mpif90'. Is that right?

[Daniele Varsano]

Dear Fabio,
you can try the following:

1) check if mpif90 link to intel compilers, just type mpif90 --version or similar.
2) if QE do works with your mpirun, can you check which compilers and wrappers were used?
3) specify the precompiler only CPP='icc -E' and see if the configure does the right job, even if I presume mpiifort will be used.
4) specify MPIFC='mpif90' only.
5) Try a compilation with gfortran instead than intel, in case you have gfortran installed.

Do not have much more more solution.

Dear Daniele,


1) Yes it links to intel compilers (ifort).
2) QE is using the mpif90 which links to ifort.
3) To be tested.
4) It works now. I can run yambo in parallel mode.

Thank you,

Fabio

Great!!

Enjoy the yambo experience,
