Classes
struct	getfem::true_thread_policy
	Thread policy, where partitioning is based on true threads. More...
struct	getfem::global_thread_policy
	Thread policy, regulated by partition_master (can be true thread- or partition-based) More...
class	getfem::detail::omp_distribute_impl< std::vector< T >, thread_policy, vector_tag >
	Specialization for std::vector<T>, adds vector indexing operator. More...
class	getfem::detail::omp_distribute_impl< bool, thread_policy, bool_tag >
	Specialization for bool, to circumvent the shortcomings of standards library's specialization for std::vector<bool>, we use std::vector<int> instead. More...
class	getfem::omp_distribute< T, thread_policy >
	Use this template class for any object you want to distribute to open_MP threads. More...
class	getfem::partition_iterator
	Iterator that runs over partitions on the current thread and sets the global (but thread-specific) partition during incrementation. More...
class	getfem::partition_master
	A singleton that Manages partitions on individual threads. More...
class	getfem::parallel_boilerplate
	Encapsulates open_mp-related initialization and de-initialization. More...

• passing exceptions to the master thread
• thread-safe locale
