      First implementation of an autotuning procedure · 0ebe4802
      Lorenz Huedepohl authored
      To be used like this
      
         class(elpa_t), pointer      :: e
         class(elpa_autotune_t), pointer :: tune_state
      
         e => elpa_allocate()
         call e%set(...)
         [...]
         assert_elpa_ok(e%setup())
      
         tune_state => e%autotune_setup(ELPA_AUTOTUNE_FAST, ELPA_AUTOTUNE_DOMAIN_REAL)
      
         ! Autotuning loop, continues until all combinations have been tried
         do while (e%autotune_step(tune_state))
           ! Do the steps that are representative of your calculation
           call e%eigenvectors(a, ev, z, error)
         end do
      
         ! Fix best parameters, and de-allocate the autotune object
         call e%autotune_set_best(tune_state)
         call elpa_autotune_deallocate(tune_state)
