Note on EZFIO.cfg

Format specification:

Required:
    [<provider_name>]   The name of the provider in irp.f90 and in the EZFIO lib
    doc:<str>           The plain text documentation
    type:<str>          A type supported by the OCaml.
                            type `ei_handler.py get_supported_type` for a list
    interface:<str>     The interface is a list of strings sepeared by ","  which can contain :
                          - ezfio : to build the EZFIO API
                          - provider : to build the corresponding providers 
                          - ocaml : to build the corresponding bindings in OCaml
Optional:
    default: <str>      The default value,
                            needed if 'ocaml' is in interface list.
                           ! No list is allowed for now !
    size: <str>         The size information.
                            (by default is one)
                            Example : 1; =sum(ao_num); (ao_num,3)
                            WARNING : The module and the value are separed by a "." not a "_".
                            For example (determinants.n_det)
    ezfio_name: <str>   The name in the EZFIO API
                             (by default is <provider_name>)
    ezfio_dir: <str>    Will be the directory of EZFIO.
                              (by default is <module_lower>)

Example of EZFIO.cfg:

[thresh_SCF]
doc: Threshold on the convergence of the Hartree Fock energy
type: Threshold
default: 1.e-10
interface: provider,ezfio,ocaml
size: 1

[energy]
type: Strictly_negative_float
doc: Calculated HF energy
interface: ezfio

FAQ

My hartree-Fock segfault !

A old version of Lapack have a bug. Just relax your convergence criterium

Error: ezfio_* is already defined.

Why ?

You have two or more ezfio configuration files for the same variable. Check files in $QP_ROOT/install/EZFIO/config/ and the all the EZFIO.cfg.

Fix

- rm $QP_ROOT/install/EZFIO/config/*
- ninja

Error: Seg Fault (139)

Segmentation fault (core dumped)
Program exited with code 139.

Why ?

It’s caused when we call the DGEMM routine of LAPACK.

Fix

Set ulimit -s unlimited, before runing qp_run. It seems to fix the problem.

Error: f77zmq not symbol found

In the Makefile of the f77zmq, you should NOT use ar but libtool -static
