Interfaces

public interface dbcsr_init_lib

  • private subroutine dbcsr_init_lib_def(mp_comm, io_unit, accdrv_active_device_id)

    Initialize the DBCSR library using internal loggers and timer callbacks We do not need this routine within the library, so we keep the communicator as a handle and convert it here to a communicator type

    Arguments

    Type IntentOptional Attributes Name
    integer, intent(in) :: mp_comm
    integer, intent(in), optional :: io_unit
    integer, intent(in), optional :: accdrv_active_device_id

  • private subroutine dbcsr_init_lib_hooks(mp_comm, in_timeset_hook, in_timestop_hook, in_abort_hook, in_warn_hook, io_unit, accdrv_active_device_id)

    Initialize the DBCSR library using external loggers and timer callbacks We do not need this routine within the library, so we keep the communicator as a handle and convert it here to a communicator type
