Member Function Documentation

◆ maximum_concurrent_threads()

index_t GEO::MonoThreadingThreadManager::maximum_concurrent_threads ( )
overridevirtual

Gets the maximum number of possible concurrent threads.

Returns
The maximum number of possible concurrent threads allowed by this manager. It depends on the physical number of cores (including hyper-threading or not) and the technology implemented by this manager.
See also
Process::number_of_cores()
Note
This implementation always returns 1.

Implements GEO::ThreadManager.

◆ run_concurrent_threads()

void GEO::MonoThreadingThreadManager::run_concurrent_threads ( ThreadGroup threads,
index_t  max_threads 
)
overrideprotectedvirtual

Runs a group of Threads concurrently.

This start the concurrent execution of the threads contained in vector threads, using the given number of threads max_threads. The execution terminates when the last thread terminates.

Parameters
[in]threadsthe vector of threads to be executed.
[in]max_threadsmaximum number of threads allowed for this execution. It is always greater than one
Note
This implementation always executes threads sequentially.

Implements GEO::ThreadManager.
