static bool is_rethrow_broken
static void terminate_auto_initialized_scheduler()
Undo automatic initialization if necessary; call when a thread exits.
static void print_version_info()
Class that supports TBB initialization.
static generic_scheduler * init_scheduler_weak()
Automatic initialization of scheduler in a master thread with default settings without arena.
static generic_scheduler * local_scheduler()
Obtain the thread-local instance of the TBB scheduler.
static bool speculation_enabled()
static bool rethrow_exception_broken()
static const int automatic
Typedef for number of threads that is automatic.
The class handles access to the single instance of market, and to TLS to keep scheduler instances.
static unsigned default_num_threads()
static void release_resources()
Destroy the thread-local storage key and deinitialize RML.
static rml::tbb_server * create_rml_server(rml::tbb_client &)
static generic_scheduler * local_scheduler_if_initialized()
Work stealing task scheduler.
static void sign_off(generic_scheduler *s)
Unregister TBB scheduler instance from thread-local storage.
static void assume_scheduler(generic_scheduler *s)
Temporarily set TLS slot to the given scheduler.
static bool does_client_join_workers(const tbb::internal::rml::tbb_client &client)
static rml::tbb_factory theRMLServerFactory
static bool UsePrivateRML
static uintptr_t tls_value_of(generic_scheduler *s)
Computes the value of the TLS.
static bool is_speculation_enabled
static void acquire_resources()
Create key for thread-local storage and initialize RML.
static void sign_on(generic_scheduler *s)
Register TBB scheduler instance in thread-local storage.
static generic_scheduler * tls_scheduler_of(uintptr_t v)
Converts TLS value to the scheduler pointer.
static void initialize_rml_factory()
static basic_tls< uintptr_t > theTLS
TLS for scheduler instances associated with individual threads.
int AvailableHwConcurrency()
Returns maximal parallelism level supported by the current OS configuration.
static void one_time_init()
static unsigned DefaultNumberOfThreads
Caches the maximal level of parallelism supported by the hardware.
std::size_t stack_size_type
void const char const char int ITT_FORMAT __itt_group_sync s
static generic_scheduler * local_scheduler_weak()
static void auto_terminate(void *scheduler)
The internal routine to undo automatic initialization.
static bool is_set(generic_scheduler *s)
Used to check validity of the local scheduler TLS contents.
static bool terminate_scheduler(generic_scheduler *s, bool blocking)
Processes scheduler termination request (possibly nested) in a master thread.
static generic_scheduler * init_scheduler(int num_threads, stack_size_type stack_size, bool auto_init)
Processes scheduler initialization request (possibly nested) in a master thread.
