| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variable. In addition to igamma(a, x), this code implements: * igamma_der_a(a, x) = d igamma(a, x) / da -- derivative of igamma with respect to the parameter * gamma_sample_der_alpha(alpha, sample) -- reparameterization derivative of a Gamma(alpha, 1) random variable sample with respect to the alpha parameter The derivatives are computed by forward mode differentiation of the igamma(a, x) code. Although gamma_sample_der_alpha can be implemented via igamma_der_a, a separate function is more accurate and efficient due to analytical cancellation of some terms. All three functions are implemented by a method parameterized with "mode" that always computes the derivatives, but does not return them unless required by the mode. The compiler is expected to (and, based on benchmarks, does) skip the unnecessary computations depending on the mode.
| | | * Adding support for using Eigen in HIP kernels.Gravatar Deven Desai2018-06-06
| | |/ | |/| | | | | | | | | | | | | | | | | | | | | | This commit enables the use of Eigen on HIP kernels / AMD GPUs. Support has been added along the same lines as what already exists for using Eigen in CUDA kernels / NVidia GPUs. Application code needs to explicitly define EIGEN_USE_HIP when using Eigen in HIP kernels. This is because some of the CUDA headers get picked up by default during Eigen compile (irrespective of whether or not the underlying compiler is CUDACC/NVCC, for e.g. Eigen/src/Core/arch/CUDA/Half.h). In order to maintain this behavior, the EIGEN_USE_HIP macro is used to switch to using the HIP version of those header files (see Eigen/Core and unsupported/Eigen/CXX11/Tensor) Use the "-DEIGEN_TEST_HIP" cmake option to enable the HIP specific unit tests.

* | Set EIGEN_IDEAL_MAX_ALIGN_BYTES correctly for AVX512 buildsGravatar Mark D Ryan2018-05-17
| | | | | | | | | | | | | | | | | | | | | | | | bug #1548 The macro EIGEN_IDEAL_MAX_ALIGN_BYTES is being incorrectly set to 32 on AVX512 builds. It should be set to 64. In the current code it is only set to 64 if the macro EIGEN_VECTORIZE_AVX512 is defined. This macro does get defined in AVX512 builds in Core, but only after Macros.h, the file that defines EIGEN_IDEAL_MAX_ALIGN_BYTES, has been included. This commit fixes the issue by setting EIGEN_IDEAL_MAX_ALIGN_BYTES to 64 if __AVX512F__ is defined.
