Data Types  
type  rvAction 
this encapsulates all the information needed to perfrom the correct action an instance is returned from rvNextAction More...  
Functions/Subroutines  
logical function, public  rvInit (steps, checkpoints, errorMsgRevolve, anActionInstance, bundle) 
method to initialize the internal state; must be called before any call to rvNextAction More...  
logical function, public  rvAdjust (steps, checkpoints, errorMsgRevolve) 
method to change the internal state for the total number of steps/checkpoints; must be called after rvInit More...  
subroutine, public  rvVerbose (level) 
method to set the verbosity to a level in [03] as described for ourVerbosity More...  
type(rvaction) function, public  rvNextAction () 
the method to determine the next action; to be called in an unbound loop after rvInit More...  
integer function, public  rvGuess (steps, bundle) 
estimates the number of checkpoints required; equivalent to adjust in Alg. 799 More...  
double precision function, public  rvFactor (steps, checkpoints, bundle) 
computes the run time overhead factor; equivalent to expense in Alg. 799 More...

integer, parameter, public  rvdone =6 
we are done with adjoining the loop equivalent to the terminate enum value in Alg. 799 More...  
integer, parameter, public  rverror =7 
an error has occurred equivalent to the error enum value in Alg. 799; see also errorMsgRevolve in rvAction More...  
integer  ourbundle = 1 
the number of iterations that may be bundled for a taping/adjoining sweep; set by calling rvInit; not supposed to be set/used directly by the user; More...

logical function, public revolve::rvAdjust  (  integer, intent(in)  steps, 
integer, intent(in)  checkpoints,  
character(*), intent(out)  errorMsgRevolve  
) 
method to change the internal state for the total number of steps/checkpoints; must be called after rvInit
steps  the total number of steps in the iteration; equivalent to steps in Alg. 799 
errorMsgRevolve  set when an error condition occurs; else set to "none" 
.true.
if successfull, else .false.
ansd errorMsgRevolve
will be set Definition at line 261 of file revolve.f90.
double precision function, public revolve::rvFactor  (  integer, intent(in)  steps, 
integer, intent(in)  checkpoints,  
integer, intent(in), optional  bundle  
) 
computes the run time overhead factor; equivalent to expense
in Alg. 799
steps  is the number of iterations 
checkpoints  is the number of allowed checkpoints 
bundle  is optional; detaults to 1, if specified indicates the number of iterations bundled in one tape/adjoint sweep 
this method does not change the internal state and does not require rvInit
Definition at line 514 of file revolve.f90.
integer function, public revolve::rvGuess  (  integer, intent(in)  steps, 
integer, intent(in), optional  bundle  
) 
estimates the number of checkpoints required; equivalent to adjust
in Alg. 799
steps  is the number of iterations 
bundle  is optional; detaults to 1, if specified indicates the number of iterations bundled in one tape/adjoint sweep 
this method does not change the internal state and does not require rvInit
Definition at line 448 of file revolve.f90.
logical function, public revolve::rvInit  (  integer, intent(in)  steps, 
integer, intent(in)  checkpoints,  
character(*), intent(out)  errorMsgRevolve,  
type(rvaction), optional  anActionInstance,  
integer, intent(in), optional  bundle  
) 
method to initialize the internal state; must be called before any call to rvNextAction
steps  the total number of steps in the iteration; equivalent to steps in Alg. 799 
checkpoints  the total number of checkpoints allowed to be stored at any time; equivalent to snaps in Alg. 799 
errorMsgRevolve  set when an error condition occurs; else set to "none" 
anActionInstance  if supplied initializes its contents 
bundle  if supplied initializes ourBundle 
.true.
if successfull, else .false.

type(rvaction) function, public revolve::rvNextAction  (  ) 
the method to determine the next action; to be called in an unbound loop after rvInit
rvAction
set to describe the next action (see the member documentation);this method modifies the internal state; it is approximately equivalent to the method revolve
in Alg. 799
available checkpoint slots
local copy of previous subrange start
