這消息晚了幾天…之前在 nVidia 放出 195.39 的測試版驅動程式時就就提過了，CUDA 3.0 應該是要出了。而在前幾天，nVidia 論壇上論壇上，也出現他的消息了∼全文可以參考《CUDA Toolkit 3.0 beta released》一文；不過，目前也還只是針對註冊的使用者進行封測而已。更新重點如下：
- CUDA Driver / Runtime Buffer Interoperability, which allows applications using the CUDA Driver API to also use libraries implemented using the CUDA C Runtime.
- A new, separate version of the CUDA C Runtime (CUDART) for debugging in emulation-mode.
- C Class Inheritance and Template Inheritance support for increased programmer productivity
- A new unified interoperability API for Direct3D and OpenGL, with support for:
- OpenGL texture interop
- Direct3D 11 interop support
- cuda-gdb hardware debugging support for applications that use the CUDA Driver API
- New CUDA Memory Checker reports misalignment and out of bounds errors, available as a debugging mode within cuda-gdb and also as a stand-alone utility.
- CUDA Toolkit libraries are now versioned, enabling applications to require a specific version, support multiple versions explicitly, etc.
- CUDA C/C kernels are now compiled to standard ELF format
- Support for all the OpenCL features in the latest R195.39 beta driver:
- Double Precision
- OpenGL Interoperability, for interactive high performance visualization
- Query for Compute Capability, so you can target optimizations for GPU architectures (cl_nv_device_attribute_query)
- Ability to control compiler optimization settings, etc. via support for NVIDIA Compiler Flags (cl_nv_compiler_options)
- OpenCL Images support, for better/faster image filtering
- 32-bit Atomics for fast, convenient data manipulation
- Byte Addressable Stores, for faster video/image processing and compression algorithms
- Support for the latest OpenCL spec revision 48 and latest official Khronos OpenCL headers as of 11/1/2009
- Early support for the Fermi architecture, including:
- Native 64-bit GPU support
- Multiple Copy Engine support
- ECC reporting
- Concurrent Kernel Execution
- Fermi HW debugging support in cuda-gdb
在 Heresy 來看，主要的重點，一個就是之前在 Fermi 發表時所提的支援 C ；但是比較怪的，是他在這 Highlight list 裡並沒有把他獨立列成一項？另外，在 3.0 應該也是正式同時支援 OpenCL 和 CUDA C 了∼不過這都只是看上面的內容啦∼細節呢，應該還是要裝起來玩過才知道了。（不過，滿囧的是，NVIDIA_CUDA_ProgrammingGuide_3.0.pdf 裡還是 2.3 啊…）
