typedef struct wkf_shared_iterator_struct wkf_shared_iterator_t
 

iterator used for dynamic load balancing

typedef struct wkf_tasktile_struct wkf_tasktile_t
 

Task tile struct for stack, iterator, and scheduler routines; 'start' is inclusive, 'end' is exclusive. This yields a half-open interval that corresponds to a typical 'for' loop.

typedef struct wkf_threadlaunch_struct wkf_threadlaunch_t
 

Routines to generate a pool of threads which then grind through a dynamically load balanced work queue implemented as a shared iterator. No exception handling is possible, just a simple all-or-nothing attept. Useful for simple calculations that take very little time. An array of threads is generated, launched, and joined all with one call.

typedef struct wkf_threadpool_struct wkf_threadpool_t
 

typedef struct wkf_threadpool_workerdata_struct wkf_threadpool_workerdata_t
 

thread-specific handle data for workers
