+****************
+
+On the hardware side, there is the hierarchy (fine to coarse):
+
+* work item (thread)
+
+* wavefront
+
+* work group
+
+* compute unite (CU)
+
+All OpenMP and OpenACC levels are used, i.e.
+
+* OpenMP's simd and OpenACC's vector map to work items (thread)
+
+* OpenMP's threads ('parallel') and OpenACC's workers map
+        to wavefronts
+
+* OpenMP's teams and OpenACC's gang use a threadpool with the
+        size of the number of teams or gangs, respectively.
+
+The used sizes are
+
+* Number of teams is the specified ``num_teams`` (OpenMP) or
+        ``num_gangs`` (OpenACC) or otherwise the number of CU
+
+* Number of wavefronts is 4 for gfx900 and 16 otherwise;
+        ``num_threads`` (OpenMP) and ``num_workers`` (OpenACC)
+        overrides this if smaller.
+
+* The wavefront has 102 scalars and 64 vectors
+
+* Number of workitems is always 64
+
+* The hardware permits maximally 40 workgroups/CU and
+        16 wavefronts/workgroup up to a limit of 40 wavefronts in total per CU.
+
+* 80 scalars registers and 24 vector registers in non-kernel functions
+        (the chosen procedure-calling API).
+
+* For the kernel itself: as many as register pressure demands (number of
+        teams and number of threads, scaled down if registers are exhausted)
+
+The implementation remark:
+
+* I/O within OpenMP target regions and OpenACC parallel/kernels is supported
+        using the C library ``printf`` functions and the Fortran
+        ``print`` / ``write`` statements.

+
+CUDA Streams Usage
+------------------
+
+This applies to the ``nvptx`` plugin only.
+
+The library provides elements that perform asynchronous movement of
+data and asynchronous operation of computing constructs.  This
+asynchronous functionality is implemented by making use of CUDA
+streams [#f1]_.
+
+The primary means by that the asynchronous functionality is accessed
+is through the use of those OpenACC directives which make use of the
+``async`` and ``wait`` clauses.  When the ``async`` clause is
+first used with a directive, it creates a CUDA stream.  If an
+``async-argument`` is used with the ``async`` clause, then the
+stream is associated with the specified ``async-argument``.
+
+Following the creation of an association between a CUDA stream and the
+``async-argument`` of an ``async`` clause, both the ``wait``
+clause and the ``wait`` directive can be used.  When either the
+clause or directive is used after stream creation, it creates a
+rendezvous point whereby execution waits until all operations
+associated with the ``async-argument``, that is, stream, have
+completed.
+
+Normally, the management of the streams that are created as a result of
+using the ``async`` clause, is done without any intervention by the
+caller.  This implies the association between the ``async-argument``
+and the CUDA stream will be maintained for the lifetime of the program.
+However, this association can be changed through the use of the library
+function ``acc_set_cuda_stream``.  When the function
+``acc_set_cuda_stream`` is called, the CUDA stream that was
+originally associated with the ``async`` clause will be destroyed.
+Caution should be taken when changing the association as subsequent
+references to the ``async-argument`` refer to a different
+CUDA stream.

+First invocation: NVIDIA CUBLAS library API
+*******************************************
+
+In this first use case (see below), a function in the CUBLAS library is called
+prior to any of the functions in the OpenACC library. More specifically, the
+function ``cublasCreate()``.
+
+When invoked, the function initializes the library and allocates the
+hardware resources on the host and the device on behalf of the caller. Once
+the initialization and allocation has completed, a handle is returned to the
+caller. The OpenACC library also requires initialization and allocation of
+hardware resources. Since the CUBLAS library has already allocated the
+hardware resources for the device, all that is left to do is to initialize
+the OpenACC library and acquire the hardware resources on the host.
+
+Prior to calling the OpenACC function that initializes the library and
+allocate the host hardware resources, you need to acquire the device number
+that was allocated during the call to ``cublasCreate()``. The invoking of the
+runtime library function ``cudaGetDevice()`` accomplishes this. Once
+acquired, the device number is passed along with the device type as
+parameters to the OpenACC library function ``acc_set_device_num()``.
+
+Once the call to ``acc_set_device_num()`` has completed, the OpenACC
+library uses the  context that was created during the call to
+``cublasCreate()``. In other words, both libraries will be sharing the
+same context.
+
+.. code-block:: c++
+
+      /* Create the handle */
+      s = cublasCreate(&h);
+      if (s != CUBLAS_STATUS_SUCCESS)
+      {
+          fprintf(stderr, "cublasCreate failed %d\n", s);
+          exit(EXIT_FAILURE);
+      }
+
+      /* Get the device number */
+      e = cudaGetDevice(&dev);
+      if (e != cudaSuccess)
+      {
+          fprintf(stderr, "cudaGetDevice failed %d\n", e);
+          exit(EXIT_FAILURE);
+      }
+
+      /* Initialize OpenACC library and use device 'dev' */
+      acc_set_device_num(dev, acc_device_nvidia);

+First invocation: OpenACC library API
+*************************************
+
+In this second use case (see below), a function in the OpenACC library is
+called prior to any of the functions in the CUBLAS library. More specificially,
+the function ``acc_set_device_num()``.
+
+In the use case presented here, the function ``acc_set_device_num()``
+is used to both initialize the OpenACC library and allocate the hardware
+resources on the host and the device. In the call to the function, the
+call parameters specify which device to use and what device
+type to use, i.e., ``acc_device_nvidia``. It should be noted that this
+is but one method to initialize the OpenACC library and allocate the
+appropriate hardware resources. Other methods are available through the
+use of environment variables and these will be discussed in the next section.
+
+Once the call to ``acc_set_device_num()`` has completed, other OpenACC
+functions can be called as seen with multiple calls being made to
+``acc_copyin()``. In addition, calls can be made to functions in the
+CUBLAS library. In the use case a call to ``cublasCreate()`` is made
+subsequent to the calls to ``acc_copyin()``.
+As seen in the previous use case, a call to ``cublasCreate()``
+initializes the CUBLAS library and allocates the hardware resources on the
+host and the device.  However, since the device has already been allocated,
+``cublasCreate()`` will only initialize the CUBLAS library and allocate
+the appropriate hardware resources on the host. The context that was created
+as part of the OpenACC initialization is shared with the CUBLAS library,
+similarly to the first use case.

+Implementation Status and Implementation-Defined Behavior
+*********************************************************
+
+We're implementing the OpenACC Profiling Interface as defined by the
+OpenACC 2.6 specification.  We're clarifying some aspects here as
+*implementation-defined behavior*, while they're still under
+discussion within the OpenACC Technical Committee.
+
+This implementation is tuned to keep the performance impact as low as
+possible for the (very common) case that the Profiling Interface is
+not enabled.  This is relevant, as the Profiling Interface affects all
+the *hot* code paths (in the target code, not in the offloaded
+code).  Users of the OpenACC Profiling Interface can be expected to
+understand that performance will be impacted to some degree once the
+Profiling Interface has gotten enabled: for example, because of the
+*runtime* (libgomp) calling into a third-party *library* for
+every event that has been registered.
+
+We're not yet accounting for the fact that OpenACC events may
+occur during event processing.
+We just handle one case specially, as required by CUDA 9.0
+:command:`nvprof`, that ``acc_get_device_type``
+(:ref:`acc_get_device_type`)) may be called from
+``acc_ev_device_init_start``, ``acc_ev_device_init_end``
+callbacks.
+
+We're not yet implementing initialization via a
+``acc_register_library`` function that is either statically linked
+in, or dynamically via :envvar:`LD_PRELOAD`.
+Initialization via ``acc_register_library`` functions dynamically
+loaded via the :envvar:`ACC_PROFLIB` environment variable does work, as
+does directly calling ``acc_prof_register``,
+``acc_prof_unregister``, ``acc_prof_lookup``.
+
+As currently there are no inquiry functions defined, calls to
+``acc_prof_lookup`` will always return ``NULL``.
+
+There aren't separate *start*, *stop* events defined for the
+event types ``acc_ev_create``, ``acc_ev_delete``,
+``acc_ev_alloc``, ``acc_ev_free``.  It's not clear if these
+should be triggered before or after the actual device-specific call is
+made.  We trigger them after.
+
+Remarks about data provided to callbacks:
+
+acc_prof_info.event_type
+  It's not clear if for *nested* event callbacks (for example,
+  ``acc_ev_enqueue_launch_start`` as part of a parent compute
+  construct), this should be set for the nested event
+  (``acc_ev_enqueue_launch_start``), or if the value of the parent
+  construct should remain (``acc_ev_compute_construct_start``).  In
+  this implementation, the value will generally correspond to the
+  innermost nested event type.
+
+acc_prof_info.device_type
+  * For ``acc_ev_compute_construct_start``, and in presence of an
+    ``if`` clause with *false* argument, this will still refer to
+    the offloading device type.
+    It's not clear if that's the expected behavior.
+
+  * Complementary to the item before, for
+    ``acc_ev_compute_construct_end``, this is set to
+    ``acc_device_host`` in presence of an ``if`` clause with
+    *false* argument.
+    It's not clear if that's the expected behavior.
+
+acc_prof_info.thread_id
+  Always ``-1`` ; not yet implemented.
+
+acc_prof_info.async
+  * Not yet implemented correctly for
+    ``acc_ev_compute_construct_start``.
+
+  * In a compute construct, for host-fallback
+    execution/ ``acc_device_host`` it will always be
+    ``acc_async_sync``.
+    It's not clear if that's the expected behavior.
+
+  * For ``acc_ev_device_init_start`` and ``acc_ev_device_init_end``,
+    it will always be ``acc_async_sync``.
+    It's not clear if that's the expected behavior.
+
+acc_prof_info.async_queue
+  There is no limited number of asynchronous queues in libgomp.
+  This will always have the same value as ``acc_prof_info.async``.
+
+acc_prof_info.src_file
+  Always ``NULL`` ; not yet implemented.
+
+acc_prof_info.func_name
+  Always ``NULL`` ; not yet implemented.
+
+acc_prof_info.line_no
+  Always ``-1`` ; not yet implemented.
+
+acc_prof_info.end_line_no
+  Always ``-1`` ; not yet implemented.
+
+acc_prof_info.func_line_no
+  Always ``-1`` ; not yet implemented.
+
+acc_prof_info.func_end_line_no
+  Always ``-1`` ; not yet implemented.
+
+acc_event_info.event_type, acc_event_info.*.event_type
+  Relating to ``acc_prof_info.event_type`` discussed above, in this
+  implementation, this will always be the same value as
+  ``acc_prof_info.event_type``.
+
+acc_event_info.\*.parent_construct
+  * Will be ``acc_construct_parallel`` for all OpenACC compute
+    constructs as well as many OpenACC Runtime API calls; should be the
+    one matching the actual construct, or
+    ``acc_construct_runtime_api``, respectively.
+
+  * Will be ``acc_construct_enter_data`` or
+    ``acc_construct_exit_data`` when processing variable mappings
+    specified in OpenACC *declare* directives; should be
+    ``acc_construct_declare``.
+
+  * For implicit ``acc_ev_device_init_start``,
+    ``acc_ev_device_init_end``, and explicit as well as implicit
+    ``acc_ev_alloc``, ``acc_ev_free``,
+    ``acc_ev_enqueue_upload_start``, ``acc_ev_enqueue_upload_end``,
+    ``acc_ev_enqueue_download_start``, and
+    ``acc_ev_enqueue_download_end``, will be
+    ``acc_construct_parallel`` ; should reflect the real parent
+    construct.
+
+acc_event_info.\*.implicit
+  For ``acc_ev_alloc``, ``acc_ev_free``,
+  ``acc_ev_enqueue_upload_start``, ``acc_ev_enqueue_upload_end``,
+  ``acc_ev_enqueue_download_start``, and
+  ``acc_ev_enqueue_download_end``, this currently will be ``1``
+  also for explicit usage.
+
+acc_event_info.data_event.var_name
+  Always ``NULL`` ; not yet implemented.
+
+acc_event_info.data_event.host_ptr
+  For ``acc_ev_alloc``, and ``acc_ev_free``, this is always
+  ``NULL``.
+
+typedef union acc_api_info
+  ... as printed in 5.2.3. Third Argument: API-Specific
+  Information.  This should obviously be ``typedef struct
+  acc_api_info``.
+
+acc_api_info.device_api
+  Possibly not yet implemented correctly for
+  ``acc_ev_compute_construct_start``,
+  ``acc_ev_device_init_start``, ``acc_ev_device_init_end`` :
+  will always be ``acc_device_api_none`` for these event types.
+  For ``acc_ev_enter_data_start``, it will be
+  ``acc_device_api_none`` in some cases.
+
+acc_api_info.device_type
+  Always the same as ``acc_prof_info.device_type``.
+
+acc_api_info.vendor
+  Always ``-1`` ; not yet implemented.
+
+acc_api_info.device_handle
+  Always ``NULL`` ; not yet implemented.
+
+acc_api_info.context_handle
+  Always ``NULL`` ; not yet implemented.
+
+acc_api_info.async_handle
+  Always ``NULL`` ; not yet implemented.
+
+Remarks about certain event types:
+
+acc_ev_device_init_start, acc_ev_device_init_end
+  *
+    .. See 'DEVICE_INIT_INSIDE_COMPUTE_CONSTRUCT' in
+       'libgomp.oacc-c-c++-common/acc_prof-kernels-1.c',
+       'libgomp.oacc-c-c++-common/acc_prof-parallel-1.c'.
+
+    When a compute construct triggers implicit
+    ``acc_ev_device_init_start`` and ``acc_ev_device_init_end``
+    events, they currently aren't *nested within* the corresponding
+    ``acc_ev_compute_construct_start`` and
+    ``acc_ev_compute_construct_end``, but they're currently observed
+    *before* ``acc_ev_compute_construct_start``.
+    It's not clear what to do: the standard asks us provide a lot of
+    details to the ``acc_ev_compute_construct_start`` callback, without
+    (implicitly) initializing a device before?
+
+  * Callbacks for these event types will not be invoked for calls to the
+    ``acc_set_device_type`` and ``acc_set_device_num`` functions.
+    It's not clear if they should be.
+
+acc_ev_enter_data_start, acc_ev_enter_data_end, acc_ev_exit_data_start, acc_ev_exit_data_end
+  * Callbacks for these event types will also be invoked for OpenACC
+    *host_data* constructs.
+    It's not clear if they should be.
+
+  * Callbacks for these event types will also be invoked when processing
+    variable mappings specified in OpenACC *declare* directives.
+    It's not clear if they should be.
+
+Callbacks for the following event types will be invoked, but dispatch
+and information provided therein has not yet been thoroughly reviewed:
+
+* ``acc_ev_alloc``
+
+* ``acc_ev_free``
+
+* ``acc_ev_update_start``, ``acc_ev_update_end``
+
+* ``acc_ev_enqueue_upload_start``, ``acc_ev_enqueue_upload_end``
+
+* ``acc_ev_enqueue_download_start``, ``acc_ev_enqueue_download_end``
+
+During device initialization, and finalization, respectively,
+callbacks for the following event types will not yet be invoked:
+
+* ``acc_ev_alloc``
+
+* ``acc_ev_free``
+
+Callbacks for the following event types have not yet been implemented,
+so currently won't be invoked:
+
+* ``acc_ev_device_shutdown_start``, ``acc_ev_device_shutdown_end``
+
+* ``acc_ev_runtime_shutdown``
+
+* ``acc_ev_create``, ``acc_ev_delete``
+
+* ``acc_ev_wait_start``, ``acc_ev_wait_end``
+
+For the following runtime library functions, not all expected
+callbacks will be invoked (mostly concerning implicit device
+initialization):
+
+* ``acc_get_num_devices``
+
+* ``acc_set_device_type``
+
+* ``acc_get_device_type``
+
+* ``acc_set_device_num``
+
+* ``acc_get_device_num``
+
+* ``acc_init``
+
+* ``acc_shutdown``
+
+Aside from implicit device initialization, for the following runtime
+library functions, no callbacks will be invoked for shared-memory
+offloading devices (it's not clear if they should be):
+
+* ``acc_malloc``
+
+* ``acc_free``
+
+* ``acc_copyin``, ``acc_present_or_copyin``, ``acc_copyin_async``
+
+* ``acc_create``, ``acc_present_or_create``, ``acc_create_async``
+
+* ``acc_copyout``, ``acc_copyout_async``, ``acc_copyout_finalize``, ``acc_copyout_finalize_async``
+
+* ``acc_delete``, ``acc_delete_async``, ``acc_delete_finalize``, ``acc_delete_finalize_async``
+
+* ``acc_update_device``, ``acc_update_device_async``
+
+* ``acc_update_self``, ``acc_update_self_async``
+
+* ``acc_map_data``, ``acc_unmap_data``
+
+* ``acc_memcpy_to_device``, ``acc_memcpy_to_device_async``
+

+Introduction
+============
+
+.. index:: Introduction
+
+This manual documents the usage of libgomp, the GNU Offloading and
+Multi Processing Runtime Library.  This includes the GNU
+implementation of the `OpenMP <https://www.openmp.org>`_ Application
+Programming Interface (API) for multi-platform shared-memory parallel
+programming in C/C++ and Fortran, and the GNU implementation of the
+`OpenACC <https://www.openacc.org>`_ Application Programming
+Interface (API) for offloading of code to accelerator devices in C/C++
+and Fortran.
+
+Originally, libgomp implemented the GNU OpenMP Runtime Library.  Based
+on this, support for OpenACC and offloading (both OpenACC and OpenMP
+4's target construct) has been added later on, and the library's name
+changed to GNU Offloading and Multi Processing Runtime Library.

+
+On the hardware side, there is the hierarchy (fine to coarse):
+
+* thread
+
+* warp
+
+* thread block
+
+* streaming multiprocessor
+
+All OpenMP and OpenACC levels are used, i.e.
+
+* OpenMP's simd and OpenACC's vector map to threads
+
+* OpenMP's threads ('parallel') and OpenACC's workers map to warps
+
+* OpenMP's teams and OpenACC's gang use a threadpool with the
+        size of the number of teams or gangs, respectively.
+
+The used sizes are
+
+* The ``warp_size`` is always 32
+
+* CUDA kernel launched: ``dim={#teams,1,1}, blocks={#threads,warp_size,1}``.
+
+Additional information can be obtained by setting the environment variable to
+``GOMP_DEBUG=1`` (very verbose; grep for ``kernel.*launch`` for launch
+parameters).
+
+GCC generates generic PTX ISA code, which is just-in-time compiled by CUDA,
+which caches the JIT in the user's directory (see CUDA documentation; can be
+tuned by the environment variables ``CUDA_CACHE_{DISABLE,MAXSIZE,PATH}``.
+
+Note: While PTX ISA is generic, the ``-mptx=`` and ``-march=`` commandline
+options still affect the used PTX ISA code and, thus, the requirments on
+CUDA version and hardware.
+
+The implementation remark:
+
+* I/O within OpenMP target regions and OpenACC parallel/kernels is supported
+        using the C library ``printf`` functions. Note that the Fortran
+        ``print`` / ``write`` statements are not supported, yet.
+
+* Compilation OpenMP code that contains ``requires reverse_offload``
+        requires at least ``-march=sm_35``, compiling for ``-march=sm_30``
+        is not supported.

+Introduction
+************
+
+The OpenACC library uses the CUDA Driver API, and may interact with
+programs that use the Runtime library directly, or another library
+based on the Runtime library, e.g., CUBLAS [#f1]_.
+
+This chapter describes the use cases and what changes are
+required in order to use both the OpenACC library and the CUBLAS and Runtime
+libraries within a program.
+
+.. [#f1] See section 2.26,
+  "Interactions with the CUDA Driver API" in
+  "CUDA Runtime API", Version 5.5, and section 2.27, "VDPAU
+  Interoperability", in "CUDA Driver API", TRM-06703-001, Version 5.5,
+  for additional information on library interoperability.

+
+OpenACC library and environment variables
+*****************************************
+
+There are two environment variables associated with the OpenACC library
+that may be used to control the device type and device number:
+:envvar:`ACC_DEVICE_TYPE` and :envvar:`ACC_DEVICE_NUM`, respectively. These two
+environment variables can be used as an alternative to calling
+``acc_set_device_num()``. As seen in the second use case, the device
+type and device number were specified using ``acc_set_device_num()``.
+If however, the aforementioned environment variables were set, then the
+call to ``acc_set_device_num()`` would not be required.
+
+The use of the environment variables is only relevant when an OpenACC function
+is called prior to a call to ``cudaCreate()``. If ``cudaCreate()``
+is called prior to a call to an OpenACC function, then you must call
+``acc_set_device_num()`` [#f1]_.
+
+.. -
+   OpenACC Profiling Interface
+   -
+
+.. [#f1] More complete information
+  about :envvar:`ACC_DEVICE_TYPE` and :envvar:`ACC_DEVICE_NUM` can be found in
+  sections 4.1 and 4.2 of the `OpenACC <https://www.openacc.org>`_
+  Application Programming Interface”, Version 2.6.

+  These routines return the value of the specified :samp:`{property}` for the

+  Integer-valued and string-valued properties are returned by
+  ``acc_get_property`` and ``acc_get_property_string`` respectively.
+  The Fortran ``acc_get_property_string`` subroutine returns the string
+  retrieved in its fourth argument while the remaining entry points are
+  functions, which pass the return value as their result.
+
+  Note for Fortran, only: the OpenACC technical committee corrected and, hence,
+  modified the interface introduced in OpenACC 2.6.  The kind-value parameter
+  ``acc_device_property`` has been renamed to ``acc_device_property_kind``
+  for consistency and the return type of the ``acc_get_property`` function is
+  now a ``c_size_t`` integer instead of a ``acc_device_property`` integer.
+  The parameter ``acc_device_property`` will continue to be provided,
+  but might be removed in a future version of GCC.

+
+GOMP_CPU_AFFINITY -- Bind threads to specific CPUs
+**************************************************
+
+Description:
+  Binds threads to specific CPUs.  The variable should contain a space-separated
+  or comma-separated list of CPUs.  This list may contain different kinds of
+  entries: either single CPU numbers in any order, a range of CPUs (M-N)
+  or a range with some stride (M-N:S).  CPU numbers are zero based.  For example,
+  ``GOMP_CPU_AFFINITY="0 3 1-2 4-15:2"`` will bind the initial thread
+  to CPU 0, the second to CPU 3, the third to CPU 1, the fourth to
+  CPU 2, the fifth to CPU 4, the sixth through tenth to CPUs 6, 8, 10, 12,
+  and 14 respectively and then start assigning back from the beginning of
+  the list.  ``GOMP_CPU_AFFINITY=0`` binds all threads to CPU 0.
+
+  There is no libgomp library routine to determine whether a CPU affinity
+  specification is in effect.  As a workaround, language-specific library
+  functions, e.g., ``getenv`` in C or ``GET_ENVIRONMENT_VARIABLE`` in
+  Fortran, may be used to query the setting of the ``GOMP_CPU_AFFINITY``
+  environment variable.  A defined CPU affinity on startup cannot be changed
+  or disabled during the runtime of the application.
+
+  If both :envvar:`GOMP_CPU_AFFINITY` and :envvar:`OMP_PROC_BIND` are set,
+  :envvar:`OMP_PROC_BIND` has a higher precedence.  If neither has been set and
+  :envvar:`OMP_PROC_BIND` is unset, or when :envvar:`OMP_PROC_BIND` is set to
+  ``FALSE``, the host system will handle the assignment of threads to CPUs.
+
+See also:
+  :ref:`OMP_PLACES`, :ref:`OMP_PROC_BIND`

+GOMP_RTEMS_THREAD_POOLS -- Set the RTEMS specific thread pools
+**************************************************************
+
+Description:
+  This environment variable is only used on the RTEMS real-time operating system.
+  It determines the scheduler instance specific thread pools.  The format for
+  :envvar:`GOMP_RTEMS_THREAD_POOLS` is a list of optional
+  ``<thread-pool-count>[$<priority>]@<scheduler-name>`` configurations
+  separated by ``:`` where:
+
+  * ``<thread-pool-count>`` is the thread pool count for this scheduler
+    instance.
+
+  * ``$<priority>`` is an optional priority for the worker threads of a
+    thread pool according to ``pthread_setschedparam``.  In case a priority
+    value is omitted, then a worker thread will inherit the priority of the OpenMP
+    primary thread that created it.  The priority of the worker thread is not
+    changed after creation, even if a new OpenMP primary thread using the worker has
+    a different priority.
+
+  * ``@<scheduler-name>`` is the scheduler instance name according to the
+    RTEMS application configuration.
+
+  In case no thread pool configuration is specified for a scheduler instance,
+  then each OpenMP primary thread of this scheduler instance will use its own
+  dynamically allocated thread pool.  To limit the worker thread count of the
+  thread pools, each OpenMP primary thread must call ``omp_set_num_threads``.
+
+Example:
+  Lets suppose we have three scheduler instances ``IO``, ``WRK0``, and
+  ``WRK1`` with :envvar:`GOMP_RTEMS_THREAD_POOLS` set to
+  ``"1@WRK0:3$4@WRK1"``.  Then there are no thread pool restrictions for
+  scheduler instance ``IO``.  In the scheduler instance ``WRK0`` there is
+  one thread pool available.  Since no priority is specified for this scheduler
+  instance, the worker thread inherits the priority of the OpenMP primary thread
+  that created it.  In the scheduler instance ``WRK1`` there are three thread
+  pools available and their worker threads run at priority four.

+  Determines how long a threads waits actively with consuming CPU power

+  integer which gives the number of spins of the busy-wait loop.  The
+  integer may optionally be followed by the following suffixes acting
+  as multiplication factors: ``k`` (kilo, thousand), ``M`` (mega,
+  million), ``G`` (giga, billion), or ``T`` (tera, trillion).
+  If undefined, 0 is used when :envvar:`OMP_WAIT_POLICY` is ``PASSIVE``,
+  300,000 is used when :envvar:`OMP_WAIT_POLICY` is undefined and
+  30 billion is used when :envvar:`OMP_WAIT_POLICY` is ``ACTIVE``.
+  If there are more OpenMP threads than available CPUs, 1000 and 100
+  spins are used for :envvar:`OMP_WAIT_POLICY` being ``ACTIVE`` or
+  undefined, respectively; unless the :envvar:`GOMP_SPINCOUNT` is lower

+.. _omp_places:
+
+OMP_PLACES -- Specifies on which CPUs the theads should be placed
+*****************************************************************
+
+Description:
+  The thread placement can be either specified using an abstract name or by an
+  explicit list of the places.  The abstract names ``threads``, ``cores``,
+  ``sockets``, ``ll_caches`` and ``numa_domains`` can be optionally
+  followed by a positive number in parentheses, which denotes the how many places
+  shall be created.  With ``threads`` each place corresponds to a single
+  hardware thread; ``cores`` to a single core with the corresponding number of
+  hardware threads; with ``sockets`` the place corresponds to a single
+  socket; with ``ll_caches`` to a set of cores that shares the last level
+  cache on the device; and ``numa_domains`` to a set of cores for which their
+  closest memory on the device is the same memory and at a similar distance from
+  the cores.  The resulting placement can be shown by setting the
+  :envvar:`OMP_DISPLAY_ENV` environment variable.
+
+  Alternatively, the placement can be specified explicitly as comma-separated
+  list of places.  A place is specified by set of nonnegative numbers in curly
+  braces, denoting the hardware threads.  The curly braces can be omitted
+  when only a single number has been specified.  The hardware threads
+  belonging to a place can either be specified as comma-separated list of
+  nonnegative thread numbers or using an interval.  Multiple places can also be
+  either specified by a comma-separated list of places or by an interval.  To
+  specify an interval, a colon followed by the count is placed after
+  the hardware thread number or the place.  Optionally, the length can be
+  followed by a colon and the stride number -- otherwise a unit stride is
+  assumed.  Placing an exclamation mark (``!``) directly before a curly
+  brace or numbers inside the curly braces (excluding intervals) will
+  exclude those hardware threads.
+
+  For instance, the following specifies the same places list:
+  ``"{0,1,2}, {3,4,6}, {7,8,9}, {10,11,12}"`` ;
+  ``"{0:3}, {3:3}, {7:3}, {10:3}"`` ; and ``"{0:2}:4:3"``.
+
+  If :envvar:`OMP_PLACES` and :envvar:`GOMP_CPU_AFFINITY` are unset and
+  :envvar:`OMP_PROC_BIND` is either unset or ``false``, threads may be moved
+  between CPUs following no placement policy.

+Description:

+  ``TRUE``, OpenMP theads should not be moved; if set to ``FALSE``
+  they may be moved.  Alternatively, a comma separated list with the
+  values ``PRIMARY``, ``MASTER``, ``CLOSE`` and ``SPREAD`` can
+  be used to specify the thread affinity policy for the corresponding nesting
+  level.  With ``PRIMARY`` and ``MASTER`` the worker threads are in the
+  same place partition as the primary thread.  With ``CLOSE`` those are
+  kept close to the primary thread in contiguous place partitions.  And
+  with ``SPREAD`` a sparse distribution
+  across the place partitions is used.  Specifying more than one item in the
+  list will automatically enable nesting by default.
+
+  When undefined, :envvar:`OMP_PROC_BIND` defaults to ``TRUE`` when
+  :envvar:`OMP_PLACES` or :envvar:`GOMP_CPU_AFFINITY` is set and ``FALSE`` otherwise.

+  represent their language-specific counterparts.
+
+  The state of nested parallel regions at startup depends on several

+  and is set to greater than one, then nested parallel regions will be
+  enabled.  If not defined, then the value of the :envvar:`OMP_NESTED`
+  environment variable will be followed if defined.  If neither are
+  defined, then if either :envvar:`OMP_NUM_THREADS` or :envvar:`OMP_PROC_BIND`
+  are defined with a list of more than one value, then nested parallel
+  regions are enabled.  If none of these are defined, then nested parallel
+  regions are disabled by default.
+
+  Nested parallel regions can be enabled or disabled at runtime using
+  ``omp_set_nested``, or by setting the maximum number of nested
+  regions with ``omp_set_max_active_levels`` to one to disable, or
+  above one to enable.

+omp_set_nested -- Enable/disable nested parallel regions
+********************************************************
+
+Description:
+  Enable or disable nested parallel regions, i.e., whether team members
+  are allowed to create new teams.  The function takes the language-specific
+  equivalent of ``true`` and ``false``, where ``true`` enables
+  dynamic adjustment of team sizes and ``false`` disables it.
+
+  Enabling nested parallel regions will also set the maximum number of
+  active nested regions to the maximum supported.  Disabling nested parallel
+  regions will set the maximum number of active nested regions to one.

+Implementing FIRSTPRIVATE LASTPRIVATE COPYIN and COPYPRIVATE clauses
+********************************************************************
+
+This seems simple enough for PARALLEL blocks.  Create a private
+struct for communicating between the parent and subfunction.
+In the parent, copy in values for scalar and "small" structs;
+copy in addresses for others TREE_ADDRESSABLE types.  In the
+subfunction, copy the value into the local variable.
+
+It is not clear what to do with bare FOR or SECTION blocks.
+The only thing I can figure is that we do something like:
+
+.. code-block:: c++
+
+  #pragma omp for firstprivate(x) lastprivate(y)
+  for (int i = 0; i < n; ++i)
+    body;
+
+which becomes
+
+.. code-block:: c++
+
+  {
+    int x = x, y;
+
+    // for stuff
+
+    if (i == n)
+      y = y;
+  }
+
+where the "x=x" and "y=y" assignments actually have different
+uids for the two variables, i.e. not something you could write
+directly in C.  Presumably this only makes sense if the "outer"
+x and y are global variables.
+
+COPYPRIVATE would work the same way, except the structure
+broadcast would have to happen via SINGLE machinery instead.

+Note that while it looks like there is trickiness to propagating
+a non-constant STEP, there isn't really.  We're explicitly allowed
+to evaluate it as many times as we want, and any variables involved
+should automatically be handled as PRIVATE or SHARED like any other
+variables.  So the expression should remain evaluable in the
+subfunction.  We can also pull it into a local variable if we like,
+but since its supposed to remain unchanged, we can also not if we like.
+
+If we have SCHEDULE(STATIC), and no ORDERED, then we ought to be
+able to get away with no work-sharing context at all, since we can
+simply perform the arithmetic directly in each thread to divide up
+the iterations.  Which would mean that we wouldn't need to call any
+of these routines.
+
+There are separate routines for handling loops with an ORDERED
+clause.  Bookkeeping for that is non-trivial...

+In _most_ cases we can map this directly to ``__thread``.  Except
+that OMP allows constructors for C++ objects.  We can either
+refuse to support this (how often is it used?) or we can
+implement something akin to .ctors.
+
+Even more ideally, this ctor feature is handled by extensions
+to the main pthreads library.  Failing that, we can have a set
+of entry points to register ctor functions to be called.
