-=====================================================
-LLVM parallel-libs Subproject Charter
-=====================================================
-
-----------------------------------------------
-Description
-----------------------------------------------
-The LLVM open source project will contain a subproject named `parallel-libs`
-which will host the development of libraries which are aimed at enabling
-parallelism in code and which are also closely tied to compiler technology.
-Examples of libraries suitable for hosting within the `parallel-libs`
-subproject are runtime libraries and parallel math libraries. The initial
-candidates for inclusion in this subproject are **StreamExecutor** and
-**libomptarget** which would live in the `streamexecutor` and `libomptarget`
-subdirectories of `parallel-libs`, respectively.
-
-The `parallel-libs` project will host a collection of libraries where each
-library may be dependent on other libraries from the project or may be
-completely independent of any other libraries in the project. The rationale for
-hosting independent libraries within the same subproject is that all libraries
-in the project are providing related functionality that lives at the
-intersection of parallelism and compiler technology. It is expected that some
-libraries which initially began as independent will develop dependencies over
-time either between existing libraries or by extracting common code that can be
-used by each. One of the purposes of this subproject is to provide a working
-space where such refactoring and code sharing can take place.
-
-Libraries in the `parallel-libs` subproject may also depend on the LLVM core
-libraries. This will be useful for avoiding duplication of code within the LLVM
-project for common utilities such as those found in the LLVM support library.
-
-
-----------------------------------------------
-Requirements
-----------------------------------------------
-Libraries included in the `parallel-libs` subproject must strive to achieve the
-following requirements:
-
-1. Adhere to the LLVM coding standards.
-2. Use the LLVM build and test infrastructure.
-3. Be released under LLVM's license.
-
-
-Coding standards
-----------------
-Libraries in `parallel-libs` will match the LLVM coding standards. For existing
-projects being checked into the subproject as-is, an exception will be made
-during the initial check-in, with the understanding that the code will be
-promptly updated to follow the standards. Therefore, a three month grace period
-will be allowed for new libraries to meet the LLVM coding standards.
-
-Additional exceptions to strict adherence to the LLVM coding standards may be
-allowed in certain other cases, but the reasons for such exceptions must be
-discussed and documented on a case-by-case basis.
-
-
-LLVM build and test infrastructure
-----------------------------------
-Using the LLVM build and test infrastructure currently means using `cmake` for
-building, `lit` for testing, and `buildbot` for automating build and testing.
-This project will follow the main LLVM project conventions here and track them
-as they evolve.
-
-Each subproject library will be able to build separately without a single,
-unified cmake file, but each subproject libraries will also be integrated into
-the LLVM build so they can be built directly from the top level of the LLVM
-cmake infrastructure.
-
-
-LLVM license
-------------
-For simplicity, the `parallel-libs` project will use the normal LLVM license.
-While some runtime libraries use a dual license scheme in LLVM, we anticipate
-the project removing the need for this eventually and in the interim follow the
-simpler but still permissive license. Among other things, this makes it
-straightforward for these libraries to re-use core LLVM libraries where
-appropriate.
-
-
-----------------------------------------------
-Mailing List and Bugs
-----------------------------------------------
-Two mailing lists will be set up for the project:
-
-1. parallel_libs-dev at lists.llvm.org for discussions among project developers, and
-2. parallel_libs-commits at lists.llvm.org for patches and commits to the project.
-
-Each subproject library will manage its own components in Bugzilla. So, for
-example, there can be several Bugzilla components for
diff erent parts of
-StreamExecutor, etc.

-///
-/// \b Acxxel is a library providing a modern C++ interface for managing
-/// accelerator devices such as GPUs. Acxxel handles operations such as
-/// allocating device memory, copying data to and from device memory, creating
-/// and managing device events, and creating and managing device streams.
-///
-/// \subsection ExampleUsage Example Usage
-///
-/// Below is some example code to show you the basics of Acxxel.
-///
-/// \snippet examples/simple_example.cu Example simple saxpy
-///
-/// The above code could be compiled with either `clang` or `nvcc`. Compare this
-/// with the standard CUDA runtime library code to perform these same
-/// operations:
-///
-/// \snippet examples/simple_example.cu Example CUDA simple saxpy
-///
-/// Notice that the CUDA runtime calls are not type safe. For example, if you
-/// change the type of the inputs from `float` to `double`, you have to remember
-/// to change the size calculation. If you forget, you will get garbage output
-/// data. In the Acxxel example, you would instead get a helpful compile-time
-/// error that wouldn't let you forget to change the types inside the function.
-///
-/// The Acxxel example also automatically uses the right sizes for memory
-/// copies, so you don't have to worry about computing the sizes yourself.
-///
-/// The CUDA runtime interface makes it easy to get the source and destination
-/// mixed up in a call to `cudaMemcpy`. If you pass the pointers in the wrong
-/// order or pass the wrong enum value for the direction parameter, you won't
-/// find out until runtime (if you remembered to check the error return value of
-/// `cudaMemcpy`). In Acxxel there is no verbose direction enum because the name
-/// of the function says which way the copy goes, and mixing up the order of
-/// source and destination is a compile-time error.
-///
-/// The CUDA runtime interface makes you clean up your device memory by calling
-/// `cudaFree` for each call to `cudaMalloc`. In Acxxel, you don't have to worry
-/// about that because the memory cleans itself up when it goes out of scope.
-///
-/// \subsection AcxxelFeatures Acxxel Features
-///
-/// Acxxel provides many nice features compared to the C-like interfaces, such
-/// as the CUDA runtime API, which are normally used for the host code in
-/// applications using accelerators.
-///
-/// \subsubsection TypeSafety Type safety
-///
-/// Most errors involving mixing up types, sources and destinations, or host and
-/// device memory result in helpful compile-time errors.
-///
-/// \subsubsection NoCopySizes No need to specify sizes for memory copies
-///
-/// When the arguments to copy functions such as acxxel::Platform::copyHToD know
-/// their sizes (e.g std::array, std::vector, and C-style arrays), there is no
-/// need to specify the amount of memory to copy; Acxxel will just copy the
-/// whole thing. Of course the copy functions also have overloads that accept an
-/// element count for those times when you don't want to copy everything.
-///
-/// \subsubsection MemoryCleanup Automatic memory cleanup
-///
-/// Device memory allocated with acxxel::Platform::mallocD is automatically
-/// freed when it goes out of scope.
-///
-/// \subsubsection NiceErrorHandling Error handling
-///
-/// Operations that would normally return values return acxxel::Expected obects
-/// in Acxxel. These `Expected` objects contain either a value or an error
-/// message explaining why the value is not present. This reminds the user to
-/// check for errors, but also allows them to opt-out easily be calling the
-/// acxxel::Expected::getValue or acxxel::Expected::takeValue methods. The
-/// `getValue` method returns a reference to the value, leaving the `Expected`
-/// instance as the value owner, whereas the `takeValue` method moves the value
-/// out of the `Expected` object and transfers ownership to the caller.
-///
-/// \subsubsection PlatformIndependence Platform independence
-///
-/// Acxxel code works not only with CUDA, but also with any other platform that
-/// can support its interface. For example, Acxxel supports OpenCL. The
-/// acxxel::getCUDAPlatform and acxxel::getOpenCLPlatform functions are provided
-/// to allow easy access to the built-in CUDA and OpenCL platforms. Other
-/// platforms can be created by implementing the acxxel::Platform interface, and
-/// instances of those classes can be created directly.
-///
-/// \subsubsection CUDAInterop Seamless interoperation with CUDA
-///
-/// Acxxel functions as a modern replacement for the standard CUDA runtime
-/// library and interoperates seamlessly with kernel calls.
