* CMakefile update for ROCm 4.0Gravatar Deven Desai2020-10-29
| | | | Starting with ROCm 4.0, the `hipconfig --platform` command will return `amd` (prior return value was `hcc`). Updating the CMakeLists.txt files in the test dirs to account for this change.
* Fix for ROCm (and CUDA?) breakage - 201029Gravatar Deven Desai2020-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commit breaks Eigen for ROCm (and probably CUDA too) with the following error https://gitlab.com/libeigen/eigen/-/commit/e265f7ed8e59c26e15f2c35162c6b8da1c5d594f ``` Building HIPCC object test/CMakeFiles/gpu_basic.dir/gpu_basic_generated_gpu_basic.cu.o In file included from /home/rocm-user/eigen/test/gpu_basic.cu:20: In file included from /home/rocm-user/eigen/test/main.h:355: In file included from /home/rocm-user/eigen/Eigen/QR:11: In file included from /home/rocm-user/eigen/Eigen/Core:169: /home/rocm-user/eigen/Eigen/src/Core/arch/Default/Half.h:825:76: error: use of undeclared identifier 'numext'; did you mean 'Eigen::numext'? return Eigen::half_impl::raw_uint16_to_half(__ldg(reinterpret_cast<const numext::uint16_t*>(ptr))); ^~~~~~ Eigen::numext /home/rocm-user/eigen/Eigen/src/Core/MathFunctions.h:968:11: note: 'Eigen::numext' declared here namespace numext { ^ 1 error generated when compiling for gfx900.

* Add support for Armv8.2-a __fp16Gravatar David Tellenbach2020-10-28
| | | | | | | | | | | | | | | Armv8.2-a provides a native half-precision floating point (__fp16 aka. float16_t). This patch introduces * __fp16 as underlying type of Eigen::half if this type is available * the packet types Packet4hf and Packet8hf representing float16x4_t and float16x8_t respectively * packet-math for the above packets with corresponding scalar type Eigen::half The packet-math functionality has been implemented by Ashutosh Sharma <ashutosh.sharma@amperecomputing.com>. This closes #1940.

As a result SYCL backend breaks since SYCL backend only supports packet operation for vectorized type float4 and double2. The issue has been fixed by adding scalar type float to packet operation pexp for SYCL backend.

* Fix for ROCm/HIP breakage - 201013Gravatar Deven Desai2020-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The following commit seems to have introduced regressions in ROCm/HIP support. https://gitlab.com/libeigen/eigen/-/commit/183a208212353ccf81a664d25dc7660b6269acdd It causes some unit-tests to fail with the following error ``` ... Eigen/src/Core/GenericPacketMath.h:322:3: error: no member named 'bit_and' in the global namespace; did you mean 'std::bit_and'? ... Eigen/src/Core/GenericPacketMath.h:329:3: error: no member named 'bit_or' in the global namespace; did you mean 'std::bit_or'? ... Eigen/src/Core/GenericPacketMath.h:336:3: error: no member named 'bit_xor' in the global namespace; did you mean 'std::bit_xor'? ... ``` The error occurs because, when compiling the device code in HIP/CUDA, the compiler will pick up the some of the std functions (whose calls are prefixed by EIGEN_USING_STD) from the global namespace (i.e. use ::bit_xor instead of std::bit_xor). For this to work, those functions must be declared in the global namespace in the HIP/CUDA header files. The `bit_and`, `bit_or` and `bit_xor` routines are not declared in the HIP header file that contain the decls for the std math functions ( `math_functions.h` ), and this is the cause of the error above. It seems that the newer HIP compilers do support the calling of `std::` math routines within device code, and the ideal fix here would have been to change all calls to std math functions in EIGEN to use the `std::` namespace (instead of the global namespace ), when compiling with HIP compiler. However it seems there was a recent commit to remove the EIGEN_USING_STD_MATH macro and collapse it uses into the EIGEN_USING_STD macro ( https://gitlab.com/libeigen/eigen/-/commit/4091f6b25c5ad0ca3f7c00bd82bfd7ca1bbedee3 ). Replacing all std math calls will essentially require re-surrecting the EIGEN_USING_STD_MATH macro, so not choosing that option. Also HIP compilers only have support std math calls within device code, and not all std functions (specifically not for malloc/free which are prefixed via EIGEN_USING_STD). So modyfing EIGEN_USE_STD implementation to use std:: namspace for HIP will not work either. Hence going for the ugly solution of special casing the three calls that breaking the HIP compile, to explicitly use the std:: namespace

SSE does not support conversion between 64 bit integers and double and the existing implementation of casting between Packet2d and Packer2l results in undefined behavior when casting NaN to int. Since pldexp and pfdexp only manipulate exponent fields that fit in 32 bit, this change provides specializations that use existing instructions _mm_cvtpd_pi32 and _mm_cvtsi32_pd instead.
* Fix alignedbox 32-bit precision test failure.Gravatar Antonio Sanchez2020-09-30
| | | | | | | | | | | | | | | The current `test/geo_alignedbox` tests fail on 32-bit arm due to small floating-point errors. In particular, the following is not guaranteed to hold: ``` IsometryTransform identity = IsometryTransform::Identity(); BoxType transformedC; transformedC.extend(c.transformed(identity)); VERIFY(transformedC.contains(c)); ``` since `c.transformed(identity)` is ever-so-slightly different from `c`. Instead, we replace this test with one that checks an identity transform is within floating-point precision of `c`. Also updated the condition on `AlignedBox::transform(...)` to only accept `Affine`, `AffineCompact`, and `Isometry` modes explicitly. Otherwise, invalid combinations of modes would also incorrectly pass the assertion.
