Detailed Description

A simple form of sequential fixpoint computation based on Kleene fixpoint. At each iteration, the deduction operations \( f_1, \ldots, f_n \) are simply composed by functional composition \( f = f_n \circ \ldots \circ f_1 \). This strategy basically corresponds to the Gauss-Seidel iteration method.

barrier()

CUDA void lala::GaussSeidelIteration::barrier ( )

inline

iterate()

template<class F >

CUDA local::B lala::GaussSeidelIteration::iterate ( int  n, const F &  f  ) const

inline

We iterate the function f n times: \( f(0); f(1); \ldots ; f(n); \)

Parameters

`n`	the number of call to f.
`bool	f(int i)returnstrueif something has changed fori. \returntrueif for somei,f(i)returnedtrue,false` otherwise.

fixpoint() [1/4]

template<class F , class StopFun , class M >

CUDA int lala::GaussSeidelIteration::fixpoint ( int  n, const F &  f, const StopFun &  must_stop, B< M > &  has_changed  )

inline

We execute iterate(n, f) until we reach a fixpoint or must_stop() returns true.

Parameters

`n`	the number of call to f.
`bool	f(int i)returnstrueif something has changed fori. \parambool must_stop()returnstrueif we must stop early the fixpoint computation. \paramhas_changedis set totrueif we were not yet in a fixpoint. \return The number of iterations required to reach a fixpoint or untilmust_stop()returnstrue`.

fixpoint() [2/4]

template<class F , class StopFun >

CUDA int lala::GaussSeidelIteration::fixpoint ( int  n, const F &  f, const StopFun &  must_stop  )

inline

Same as fixpoint above without has_changed.

fixpoint() [3/4]

template<class F , class M >

CUDA int lala::GaussSeidelIteration::fixpoint ( int  n, const F &  f, B< M > &  has_changed  )

inline

Same as fixpoint above with must_stop always returning false.

fixpoint() [4/4]

template<class F >

CUDA int lala::GaussSeidelIteration::fixpoint ( int  n, const F &  f  )

inline

Same as fixpoint above without has_changed and with must_stop always returning false.
