qmckl.h header file

This file produces the qmckl.h header file, which is to be included when qmckl functions are used.

We also create here the qmckl_f.f90 which is the Fortran interface file.

Constants

Success/failure

These are the codes returned by the functions to indicate success or failure. All such functions should have as a return type qmckl_exit_code.

#define QMCKL_SUCCESS 0
#define QMCKL_FAILURE 1

typedef int32_t qmckl_exit_code;
typedef int64_t qmckl_context ;

integer, parameter :: QMCKL_SUCCESS = 0
integer, parameter :: QMCKL_FAILURE = 0

Precision-related constants

Controlling numerical precision enables optimizations. Here, the default parameters determining the target numerical precision and range are defined.

#define QMCKL_DEFAULT_PRECISION 53
#define QMCKL_DEFAULT_RANGE     11

integer, parameter :: QMCKL_DEFAULT_PRECISION = 53
integer, parameter :: QMCKL_DEFAULT_RANGE = 11
