#include <threading.h>
Public Attributes | |
volatile int * | nzeros |
Pointer to the integer that holds the number of zeros computed until now. | |
int | required_zeros |
The number of well approximated roots required to stop iteration packet. | |
volatile int * | it |
Pointer to the integer that holds the number of iterations performed until now. | |
mps_context * | s |
The pointer to the mps_context struct. | |
int | thread |
The index of this thread. | |
int | n_threads |
The total number of threads. | |
volatile mps_boolean * | excep |
Pointer to the boolean excep value. Setting this to true cause the iteration to enter exception state. More... | |
pthread_mutex_t * | aberth_mutex |
Array of n mutexes where n = s->n , i.e. is the total number of roots of the polynomial. More... | |
pthread_mutex_t * | global_aberth_mutex |
Global aberth mutex used to coordinate all aberth computations. | |
pthread_mutex_t * | roots_mutex |
Array of n mutexes that gets locked when a thread start to iterate over a root. This is done to ensure that only a thread at a time is iterating over a root. | |
pthread_mutex_t * | gs_mutex |
Global state mute used to synchronize some (hopefully not so many) global operation. | |
mps_thread_job_queue * | queue |
Pointer to the mps_thread_job_queue that the thread may query for other work. | |
Data packed to be passed to a new thread that will perform floating point, dpe or multiprecision iterations.
pthread_mutex_t* mps_thread_worker_data::aberth_mutex |
Array of n
mutexes where n = s->n
, i.e. is the total number of roots of the polynomial.
The mutex in position i
gets locked when a thread needs to read and/or write from/to the i-th root.
volatile mps_boolean* mps_thread_worker_data::excep |
Pointer to the boolean excep value. Setting this to true cause the iteration to enter exception state.
If this state is reached all threads returns because no more iteration are needed / useful.
