release_0.84.01

Release:0.84.01
Date: 2016.04.25

• Refactor HIP make and install system:
  • Move to CMake. Refer to the installation section in README.md for details.
  • Split source into multiple modular .cpp and .h files.
  • Create static library and link.
  • Set HIP_PATH to install.
• Make hipDevice and hipStream thread-safe.
  • Prefered hipStream usage is still to create new streams for each new thread, but it works even if you don;t.
• Improve automated platform detection: If AMD GPU is installed and detected by driver, default HIP_PLATFORM to hcc.
• HIP_TRACE_API now prints arguments to the HIP function (in addition to name of function).
• Deprecate hipDeviceGetProp (Replace with hipGetDeviceProp)
• Deprecate hipMallocHost (Replace with hipHostMalloc)
• Deprecate hipFreeHost (Replace with hipHostFree)
• The mixbench benchmark tool for measuring operational intensity now has a HIP target, in addition to CUDA and OpenCL. Let the comparisons begin. :)
