elpa_autotune_setup(3) Library Functions Manual elpa_autotune_setup(3)

NAME

elpa_autotune_setup - creates 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

FORTRAN INTERFACE

use elpa
class(elpa_t), pointer :: elpa_handle
class(elpa_autotune_t), pointer :: autotune_handle

autotune_handle= elpa_handle%autotune_setup (level, domain)

With the definitions of the input and output variables:

The level of the autotuning, at the moment ELPA_AUTOTUNE_FAST is supported
The domain (real or complex) of the autotuning, can be either ELPA_AUTOTUNE_DOMAIN_REAL or ELPA_AUTOTUNE_DOMAIN_COMPLEX

C/C++ INTERFACE

#include <elpa/elpa.h>
elpa_t elpa_handle;
elpa_autotune_t autotune_handle;

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

With the definitions of the input and output variables:

The handle of an ELPA object, obtained before with elpa_allocate(3)
The level of the autotuning, at the moment "ELPA_AUTOTUNE_FAST" is supported
The domain (real or complex) of the autotuning, can be either "ELPA_AUTOTUNE_DOMAIN_REAL" and "ELPA_AUTOTUNE_DOMAIN_COMPLEX
The created handle of the autotune object

DESCRIPTION

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