| * Fix AVX512 implementations of psqrtGravatar Mark D Ryan2018-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes the AVX512 implementations of psqrt in the same way that 3ed67cb0bb4af65fbf243df598604a8c7630bf7d fixed the AVX2 version of this function. The AVX512 versions of psqrt incorrectly return -0.0 for negative values, instead of NaN. Fixing the issues requires adding some additional instructions that slow down the algorithms. A similar test to the one used in 3ed67cb0bb4af65fbf243df598604a8c7630bf7d shows that the corrected Packet16f code runs at 73% of the speed of the existing code, while the corrected Packed8d function runs at 68% of the original.

The remaining problem is that we don't have any mechanism to accurately determine whether a type is relocatable or not, so currently let's be super conservative using either RequireInitialization or std::is_trivially_copyable
| * applying EIGEN_DECLARE_TEST to *gpu* testsGravatar Deven Desai2018-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | Also, a few minor fixes for GPU tests running in HIP mode. 1. Adding an include for hip/hip_runtime.h in the Macros.h file For HIP __host__ and __device__ are macros which are defined in hip headers. Their definitions need to be included before their use in the file. 2. Fixing the compile failure in TensorContractionGpu introduced by the commit to "Fuse computations into the Tensor contractions using output kernel" 3. Fixing a HIP/clang specific compile error by making the struct-member assignment explicit

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The major changes are 1. Moving CUDA/PacketMath.h to GPU/PacketMath.h 2. Moving CUDA/MathFunctions.h to GPU/MathFunction.h 3. Moving CUDA/CudaSpecialFunctions.h to GPU/GpuSpecialFunctions.h The above three changes effectively enable the Eigen "Packet" layer for the HIP platform 4. Merging the "hip_basic" and "cuda_basic" unit tests into one ("gpu_basic") 5. Updating the "EIGEN_DEVICE_FUNC" marking in some places The change has been tested on the HIP and CUDA platforms.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AVX512 version of ptranpose for PacketBlock<Packet16h,16> was reordering the PacketBlock argument incorrectly. This lead to errors in the multiplication of matrices composed of 16 bit floats on AVX512 machines, if at least of the matrices was using RowMajor order. This error is responsible for one tensorflow unit test failure on AVX512 machines: //tensorflow/python/kernel_tests:batch_matmul_op_test

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two major changes (and a few minor ones which are not listed here...see PR discussion for details) 1. Eigen::half implementations for HIP and CUDA have been merged. This means that - `CUDA/Half.h` and `HIP/hcc/Half.h` got merged to a new file `GPU/Half.h` - `CUDA/PacketMathHalf.h` and `HIP/hcc/PacketMathHalf.h` got merged to a new file `GPU/PacketMathHalf.h` - `CUDA/TypeCasting.h` and `HIP/hcc/TypeCasting.h` got merged to a new file `GPU/TypeCasting.h` After this change the `HIP/hcc` directory only contains one file `math_constants.h`. That will go away too once that file becomes a part of the HIP install. 2. new macros EIGEN_GPUCC, EIGEN_GPU_COMPILE_PHASE and EIGEN_HAS_GPU_FP16 have been added and the code has been updated to use them where appropriate. - `EIGEN_GPUCC` is the same as `(EIGEN_CUDACC || EIGEN_HIPCC)` - `EIGEN_GPU_DEVICE_COMPILE` is the same as `(EIGEN_CUDA_ARCH || EIGEN_HIP_DEVICE_COMPILE)` - `EIGEN_HAS_GPU_FP16` is the same as `(EIGEN_HAS_CUDA_FP16 or EIGEN_HAS_HIP_FP16)`
