release_0.86.00

Release:0.86.00
Date: 2016.06.06

• Add clang-hipify : clang-based hipify tool. Improved parsing of source code, and automates
  creation of hipLaunchParm variable.
• Implement memory register / unregister commands (hipHostRegister, hipHostUnregister)
• Add cross-linking support between G++ and HCC, in particular for interfaces that use
  standard C++ libraries (ie std::vectors, std::strings). HIPCC now uses libstdc++ by default on the HCC
  compilation path.
• More samples including gpu-burn, SHOC, nbody, rtm. See HIP-Examples

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. :)

release_0.82.01

Release:0.82.01
Date: 2016.03.08

• Bump minimum required HCC workweek to 16074.
• Bump minimum required ROCK-Kernel-Driver and ROCR-Runtime to Developer Preview 2.
• Enable multi-GPU support.
  • Use hipSetDevice to select a device for subsequent kernel calls and memory allocations.
  • CUDA_VISIBLE_DEVICES / HIP_VISIBLE_DEVICE environment variable selects devices visible to the runtime.
• Support hipStreams – send sequences of copy and kernel commands to a device.
  • Asynchronous copies supported.
• Optimize memory copy operations.
• Support hipPointerGetAttribute – can determine if a pointer is host or device.
• Enable atomics to local memory.
• Support for LC Direct-To-ISA path.
• Improved free memory reporting.
  • hipMemGetInfo (report full memory used in current process).
  • hipDeviceReset (deletes all memory allocated by current process).
