NAME

elpa_autotune_setup - create an instance for autotuning of the ELPA library

Before the autotuning object can be created, an instance of the ELPA library has to be setup, see e.g. elpa_setup(3)

SYNOPSIS

use elpa

class(elpa_t), pointer :: elpa class(elpa_autotune_t), pointer :: tune_state

tune_state= elpa%autotune_setup (level, domain)

With the definitions of the input and output variables:

integer :: level ! the level of the autotuning, at the moment ELPA_AUTOTUNE_FAST is supported

integer :: domain ! the domain (real or complex) of the autotuning, can be either ELPA_AUTOTUNE_DOMAIN_REAL or ELPA_AUTOTUNE_DOMAIN_COMPLEX

#include <elpa/elpa.h>

elpa_t handle; elpa_autotune_t autotune_handle;

elpa_autotune_t autotune_handle = elpa_autotune_setup (elpa_t handle, int level, int domain);

With the definitions of the input and output variables:

elpa_t handle; // the handle of an ELPA object, obtained before with elpa_allocate(3)

int level; // the level of the autotuning, at the moment ELPA_AUTOTUNE_FAST"issupported

int domain; // the domain (real or complex) of the autotuning, can be either ELPA_AUTOTUNE_DOMAIN_REAL"andELPA_AUTOTUNE_DOMAIN_COMPLEX

elpa_autotune_t autotune_handel; // the created handle of the autotune object

Creates an ELPA autotuning object. Prior to calling the autotune_setup, an ELPA object must have been created. See elpa_setup(3)
