Derived Types

type, public ::  timer_type

Timer type that holds CPU clock counts and rate.

Components

Type Visibility Attributes Name Initial
integer(kind=i8), public :: t(2) = 0_i8

CPU clock counts t1, t2.
integer(kind=i8), public :: rate = 0_i8

CPU clock rate.

Functions

public function dm_timer_result(timer) result(duration)

Returns elapsed time between timer start and stop in seconds as 8-byte real. The result is 0.0 if the timer has not been stopped yet.

Arguments

Type IntentOptional Attributes Name
type(timer_type), intent(inout) :: timer

Timer type.

Return Value real(kind=r8)


Subroutines

public subroutine dm_timer_stop(timer, duration)

Stops the timer and optionally returns result as 8-byte real in duration.

Arguments

Type IntentOptional Attributes Name
type(timer_type), intent(inout) :: timer

Timer type.
real(kind=r8), intent(out), optional :: duration

Elapsed time between start and stop [sec].

public subroutine dm_timer_start(timer)

Starts the timer by setting clock rate and first clock count.

Arguments

Type IntentOptional Attributes Name
type(timer_type), intent(inout) :: timer

Timer type.
