Hello,

   The issue of second-underscore is not fully supported yet in BigDFT.
As it is now, BigDFT + CUDA must be compiled with two underscores. So
it means that the MPI library must have been also compiled with the two
underscores.

   On our production machine, the MPI library allows to compile the
following code
«
program toto
include "mpif.h"
call mpi_init
end program toto
»
using mpif90 or mpif90 -assume2underscores.

   Is it the case for your MPI library ? We think not, and the issue
comes from here, "mpif90 -assume2underscores" doesn't work.

   To solve this you may ask your system administrator to provide a
MPI library with two underscores. The other solution is to wait for us
to solve the issue of forcing two underscores in BigDFT, but it may
take a while :(

Damien + Luigi.
