Compiling with parallel built

Having trouble compiling the Yambo source? Using an unusual architecture? Problems with the "configure" script? This is the place to look.

If you have trouble compiling Yambo, please make sure to list:
(1) the compiler (vendor and release: e.g. intel 10.1)
(2) the architecture (e.g. 64-bit IBM SP5)
(3) if the problems occur compiling in serial/in parallel
(4) the version of Yambo (revision number/major release version)
(5) the relevant compiler error message

Dear Burak,
your compilation of Yambo is *serial*
Code: Select all
fc_kind = gfortran


Something failed in your mpi build, if you post your config.log I will have a look.

Best,
Daniele

Dear Burak,
the config.log shows indeed that MPI cannot be found and the code is compiled in serial mode.
Code: Select all
configure:8365: WARNING: could not compile a FORTRAN mpi test program. YAMBO serial only.


Are you sure you have the MPI in your machine? May be you need to load some module?
If you think you have it and it is working you can try to specify it in the configure command line:
./configure MPIFC='mpi90''

Note that at the end of the configure there is a summary of the used compilers, flag and libraries, and it is explicitly reported if the code
will be compiled in serial or in parallel mode.

Best,
Daniele
