void getfem::partition_master::set_behaviour | ( | thread_behaviour | b | ) |
Sets the behaviour for the full program: either partitioning parallel loops according to the number of true threads, specified by the user, or to the number of the fixed partitions equal to the max concurrency of the system.
The later makes the partitioning independent of the number of the threads set

size_type getfem::partition_master::get_current_partition | ( | ) | const |
active partition on the thread.
If number of threads is equal to the max concurrency of the system, then it's also the index of the actual thread

void getfem::partition_master::set_nb_partitions | ( | size_type | n | ) |
for thread_behaviour::partition_threads set the total number of partitions.
This call must be made before all the omp_distribute based classes are created. Otherwise they become invalid
