elpa_allocate - Man Page

allocate an instance of the ELPA library


Fortran Interface

use elpa
class(elpa_t), pointer :: elpa

elpa => elpa_allocate (error)

With the definitions of the input and output variables:

class(elpa_t)     :: elpa  ! returns an instance of the ELPA object
integer, optional :: error ! a returned error code

C Interface

#include <elpa/elpa.h>
elpa_t handle;

elpa_t handle = elpa_allocate(int *error);

With the definitions of the input and output variables:

elpa_t handle;  // returns an handle to the allocated ELPA object
int *error;     // a returned error code


Allocate an ELPA object. The function elpa_init(3) must be called once BEFORE elpa_allocate can be called.
