Description

Thread pool based function evaluator. This module is used by the different objects in NumCosmo that need to evaluate functions in parallel.

Functions

NcmFuncEvalLoop ()

void
(*NcmFuncEvalLoop) (glong i,
                    glong f,
                    gpointer data);

ncm_func_eval_set_max_threads ()

void
ncm_func_eval_set_max_threads (gint mt);

Set the new maximun number of threads to be used by the pool. Note that this function is global changing this will affect every place which uses these functions.

Parameters

new max threads to be used in the pool, -1 means unlimited

ncm_func_eval_threaded_loop_nw ()

void
ncm_func_eval_threaded_loop_nw (NcmFuncEvalLoop lfunc,
                                glong i,
                                glong f,
                                gpointer data,
                                guint nworkers);

Using the thread pool, evaluate fl in each value of (f -i )/nwork .

Parameters

lfunc	NcmFuncEvalLoop to be evaluated in threads.	[scope notified]
i	initial index
f	final index
data	pointer to be passed to `fl`
nworkers	number of workers.

ncm_func_eval_threaded_loop ()

void
ncm_func_eval_threaded_loop (NcmFuncEvalLoop lfunc,
                             glong i,
                             glong f,
                             gpointer data);

Using the thread pool, evaluate fl in each value of (f -i )/nthreads

Parameters

lfunc	NcmFuncEvalLoop to be evaluated in threads.	[scope notified]
i	initial index
f	final index
data	pointer to be passed to `fl`

ncm_func_eval_threaded_loop_full ()

void
ncm_func_eval_threaded_loop_full (NcmFuncEvalLoop lfunc,
                                  glong i,
                                  glong f,
                                  gpointer data);

Using the thread pool, evaluate fl sending one worker per index.

Parameters

lfunc	NcmFuncEvalLoop to be evaluated in threads.	[scope notified]
i	initial index
f	final index
data	pointer to be passed to `fl`

ncm_func_eval_log_pool_stats ()

void
ncm_func_eval_log_pool_stats (void);
