Release Notes:

 

We are pleased to release the Beignet version 0.1.

 

Beignet is a project that provides OpenCL support for Intel platforms.

It includes an LLVM/Clang based OpenCL compiler and a runtime.

This version supports GPU type context on IVY Bridge(IVB) platform only. 

 

New features in this release:

 

1. 2D image write(typed_write)/read(sampler).

2. Partial support of cl_khr_gl_sharing extension.

3. Cmake build fixup. 

4. Add/Enable some OpenCL 1.0 APIs and built-in functions.

5. Various bug fixing.

6. More unit test cases.

 

For more detailed information, please check the source

code and read the documents.
