More in detail: * OpenCL is a general GPU backend should be able to run with any GPUs or accelerators that support [OpenCL](https://en.wikipedia.org/wiki/OpenCL), including NVIDIA GPUs, AMD GPUs, as well CPU-based OpenCL implementations or things like Intel Integrated Graphics. This is the most general GPU version of KataGo and doesn't require a complicated install like CUDA does, so is most likely to work out of the box as long as you have a fairly modern GPU. **However, it also need to take some time when run for the very first time to tune itself.** For many systems, this will take 5-30 seconds, but on a few older/slower systems, may take many minutes or longer. Also, the quality of OpenCL implementations is sometimes inconsistent, particularly for Intel Integrated Graphics and for AMD GPUs that are older than several years, so it might not work for very old machines, as well as specific buggy newer AMD GPUs, see also [Issues with specific GPUs or GPU drivers](#issues-with-specific-gpus-or-gpu-drivers). * CUDA is a GPU backend specific to NVIDIA GPUs (it will not work with AMD or Intel or any other GPUs) and requires installing [CUDA](https://developer.nvidia.com/cuda-zone) and [CUDNN](https://developer.nvidia.com/cudnn) and a modern NVIDIA GPU. On most GPUs, the OpenCL implementation will actually beat NVIDIA's own CUDA/CUDNN at performance. The exception is for top-end NVIDIA GPUs that support FP16 and tensor cores, in which case sometimes one is better and sometimes the other is better. * TensorRT is similar to CUDA, but only uses NVIDIA's TensorRT framework to run the neural network with more optimized kernels. For modern NVIDIA GPUs, it should work whenever CUDA does and will usually be faster than CUDA or any other backend. + * ROCm is a GPU backend specific to AMD GPUs (it will not work with NVIDIA or Intel or any other GPUs) and requires installing [ROCm](https://rocm.docs.amd.com) and [MIOpen](https://rocm.docs.amd.com/projects/MIOpen) and a modern AMD GPU. On most GPUs, the OpenCL implementation will actually beat AMD's own ROCm/MIOpen at performance. The exception is for top-end AMD GPUs that support FP16 and stream processors, in which case sometimes one is better and sometimes the other is better. * Eigen is a *CPU* backend that should work widely *without* needing a GPU or fancy drivers. Use this if you don't have a good GPU or really any GPU at all. It will be quite significantly slower than OpenCL or CUDA, but on a good CPU can still often get 10 to 20 playouts per second if using the smaller (15 or 20) block neural nets. Eigen can also be compiled with AVX2 and FMA support, which can provide a big performance boost for Intel and AMD CPUs from the last few years. However, it will not run at all on older CPUs (and possibly even some recent but low-power modern CPUs) that don't support these fancy vector instructions. For **any** implementation, it's recommended that you also tune the number of threads used if you care about optimal performance, as it can make a factor of 2-3 difference in the speed. See "Tuning for Performance" below. However, if you mostly just want to get it working, then the default untuned settings should also be still reasonable. @@ -175,6 +180,8 @@ This section summarizes a number of common questions and issues when running Kat #### Issues with specific GPUs or GPU drivers If you are observing any crashes in KataGo while attempting to run the benchmark or the program itself, and you have one of the below GPUs, then this is likely the reason. +* **AMD GPUs** - If you choose to use ROCm backend, uou need a GPU supported with official [System requirements lists](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/reference/system-requirements.html) (at least AMD Radeon RX 7700 XT).

More in detail: * OpenCL is a general GPU backend should be able to run with any GPUs or accelerators that support [OpenCL](https://en.wikipedia.org/wiki/OpenCL), including NVIDIA GPUs, AMD GPUs, as well CPU-based OpenCL implementations or things like Intel Integrated Graphics. This is the most general GPU version of KataGo and doesn't require a complicated install like CUDA does, so is most likely to work out of the box as long as you have a fairly modern GPU. **However, it also need to take some time when run for the very first time to tune itself.** For many systems, this will take 5-30 seconds, but on a few older/slower systems, may take many minutes or longer. Also, the quality of OpenCL implementations is sometimes inconsistent, particularly for Intel Integrated Graphics and for AMD GPUs that are older than several years, so it might not work for very old machines, as well as specific buggy newer AMD GPUs, see also [Issues with specific GPUs or GPU drivers](#issues-with-specific-gpus-or-gpu-drivers). * CUDA is a GPU backend specific to NVIDIA GPUs (it will not work with AMD or Intel or any other GPUs) and requires installing [CUDA](https://developer.nvidia.com/cuda-zone) and [CUDNN](https://developer.nvidia.com/cudnn) and a modern NVIDIA GPU. On most GPUs, the OpenCL implementation will actually beat NVIDIA's own CUDA/CUDNN at performance. The exception is for top-end NVIDIA GPUs that support FP16 and tensor cores, in which case sometimes one is better and sometimes the other is better. * TensorRT is similar to CUDA, but only uses NVIDIA's TensorRT framework to run the neural network with more optimized kernels. For modern NVIDIA GPUs, it should work whenever CUDA does and will usually be faster than CUDA or any other backend. * ROCm is a GPU backend specific to AMD GPUs (it will not work with NVIDIA or Intel or any other GPUs) and requires installing [ROCm](https://rocm.docs.amd.com) and [MIOpen](https://rocm.docs.amd.com/projects/MIOpen) and a modern AMD GPU. On most GPUs, the OpenCL implementation will actually beat AMD's own ROCm/MIOpen at performance. The exception is for top-end AMD GPUs that support FP16 and stream processors, in which case sometimes one is better and sometimes the other is better. + * MIGraphX is an alternative GPU backend for AMD GPUs using AMD's MIGraphX framework instead of MIOpen. It may offer better performance than ROCm on some GPUs. Requires ROCm 7.0+ with MIGraphX installed. * Eigen is a *CPU* backend that should work widely *without* needing a GPU or fancy drivers. Use this if you don't have a good GPU or really any GPU at all. It will be quite significantly slower than OpenCL or CUDA, but on a good CPU can still often get 10 to 20 playouts per second if using the smaller (15 or 20) block neural nets. Eigen can also be compiled with AVX2 and FMA support, which can provide a big performance boost for Intel and AMD CPUs from the last few years. However, it will not run at all on older CPUs (and possibly even some recent but low-power modern CPUs) that don't support these fancy vector instructions. For **any** implementation, it's recommended that you also tune the number of threads used if you care about optimal performance, as it can make a factor of 2-3 difference in the speed. See "Tuning for Performance" below. However, if you mostly just want to get it working, then the default untuned settings should also be still reasonable. diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt index 577dfd2c3a..ba6bbd2796 100644 --- a/cpp/CMakeLists.txt +++ b/cpp/CMakeLists.txt @@ -48,7 +48,7 @@ endif() set(BUILD_DISTRIBUTED 0 CACHE BOOL "Build with http support for contributing to distributed training") set(USE_BACKEND CACHE STRING "Neural net backend") string(TOUPPER "${USE_BACKEND}" USE_BACKEND) -set_property(CACHE USE_BACKEND PROPERTY STRINGS "" CUDA TENSORRT OPENCL EIGEN ROCM) +set_property(CACHE USE_BACKEND PROPERTY STRINGS "" CUDA TENSORRT OPENCL EIGEN ROCM MIGRAPHX) set(USE_TCMALLOC 0 CACHE BOOL "Use TCMalloc") set(NO_GIT_REVISION 0 CACHE BOOL "Disable embedding the git revision into the compiled exe") @@ -206,6 +206,62 @@ elseif(USE_BACKEND STREQUAL "ROCM") # Optional: Enable model-size‑based autotuning and other macros # add_compile_definitions(HIP_SUPPORTS_FP16) +# --------------------------- MIGRAPHX backend（AMD MIGraphX graph inference） --------------------------- +elseif(USE_BACKEND STREQUAL "MIGRAPHX") + message(STATUS "-DUSE_BACKEND=MIGRAPHX, using AMD MIGraphX backend.") + + # Use standard C++ compiler with MIGraphX + set(CMAKE_CXX_STANDARD 17) + + # Find MIGraphX manually (avoid CMake config which adds hipcc-specific flags) + # Note: MIGraphX headers are split between two locations: + # - /opt/rocm/lib/migraphx/include/migraphx/ (C++ API headers like program.hpp) + # - /opt/rocm/include/migraphx/ (export.h and other common headers) + find_path(MIGRAPHX_CXX_INCLUDE_DIR migraphx/program.hpp + HINTS /opt/rocm/lib/migraphx/include + PATH_SUFFIXES include) + + find_path(MIGRAPHX_INCLUDE_DIR migraphx/export.h + HINTS /opt/rocm/include + PATH_SUFFIXES include) + + find_library(MIGRAPHX_LIBRARY migraphx + HINTS /opt/rocm/lib/migraphx/lib /opt/rocm/lib + PATH_SUFFIXES lib lib64) + + find_library(MIGRAPHX_GPU_LIBRARY migraphx_gpu + HINTS /opt/rocm/lib/migraphx/lib /opt/rocm/lib + PATH_SUFFIXES lib lib64) + + if(NOT MIGRAPHX_CXX_INCLUDE_DIR) + message(FATAL_ERROR "MIGraphX C++ headers not found.

This is the most general GPU version of KataGo and doesn't require a complicated install like CUDA does, so is most likely to work out of the box as long as you have a fairly modern GPU. **However, it also need to take some time when run for the very first time to tune itself.** For many systems, this will take 5-30 seconds, but on a few older/slower systems, may take many minutes or longer. Also, the quality of OpenCL implementations is sometimes inconsistent, particularly for Intel Integrated Graphics and for AMD GPUs that are older than several years, so it might not work for very old machines, as well as specific buggy newer AMD GPUs, see also [Issues with specific GPUs or GPU drivers](#issues-with-specific-gpus-or-gpu-drivers). * CUDA is a GPU backend specific to NVIDIA GPUs (it will not work with AMD or Intel or any other GPUs) and requires installing [CUDA](https://developer.nvidia.com/cuda-zone) and [CUDNN](https://developer.nvidia.com/cudnn) and a modern NVIDIA GPU.

It compiles the entire neural network into a single fused GPU program, which can offer better throughput than ROCm/MIOpen on some workloads. Requires ROCm 7.0+ with MIGraphX installed. Currently supports Linux only. * Eigen is a *CPU* backend that should work widely *without* needing a GPU or fancy drivers. Use this if you don't have a good GPU or really any GPU at all. It will be quite significantly slower than OpenCL or CUDA, but on a good CPU can still often get 10 to 20 playouts per second if using the smaller (15 or 20) block neural nets. Eigen can also be compiled with AVX2 and FMA support, which can provide a big performance boost for Intel and AMD CPUs from the last few years. However, it will not run at all on older CPUs (and possibly even some recent but low-power modern CPUs) that don't support these fancy vector instructions. For **any** implementation, it's recommended that you also tune the number of threads used if you care about optimal performance, as it can make a factor of 2-3 difference in the speed.

See for example these reddit threads: [[1]](https://www.reddit.com/r/Amd/comments/ebso1x/its_not_just_setihome_any_mathematic_or/) or [[2]](https://www.reddit.com/r/BOINC/comments/ebiz18/psa_please_remove_your_amd_rx5700xt_from_setihome/) or this [L19 thread](https://lifein19x19.com/viewtopic.php?f=18&t=17093). * **OpenCL Mesa** - These drivers for OpenCL are buggy. Particularly if on startup before crashing you see KataGo printing something like diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt index ba6bbd2796..d63ca69e2b 100644 --- a/cpp/CMakeLists.txt +++ b/cpp/CMakeLists.txt @@ -3,12 +3,131 @@ if(USE_BACKEND STREQUAL "METAL") project(katago LANGUAGES CXX Swift) elseif(USE_BACKEND STREQUAL "ROCM") if(WIN32) - # Windows: Use clang++ from HIP SDK (hipcc doesn't work well on Windows) - # User can override with -DCMAKE_CXX_COMPILER if needed - if(NOT DEFINED CMAKE_CXX_COMPILER) + # Normalize HIP_PATH to forward slashes. + # cmake's HIP detection calls `hipconfig --rocmpath` which returns + # backslash paths on Windows; it writes the result into the generated + # CMakeHIPCompiler.cmake without normalizing, causing "Invalid character + # escape '\T'" errors.

More in detail: * OpenCL is a general GPU backend should be able to run with any GPUs or accelerators that support [OpenCL](https://en.wikipedia.org/wiki/OpenCL), including NVIDIA GPUs, AMD GPUs, as well CPU-based OpenCL implementations or things like Intel Integrated Graphics. This is the most general GPU version of KataGo and doesn't require a complicated install like CUDA does, so is most likely to work out of the box as long as you have a fairly modern GPU. **However, it also need to take some time when run for the very first time to tune itself.** For many systems, this will take 5-30 seconds, but on a few older/slower systems, may take many minutes or longer. Also, the quality of OpenCL implementations is sometimes inconsistent, particularly for Intel Integrated Graphics and for AMD GPUs that are older than several years, so it might not work for very old machines, as well as specific buggy newer AMD GPUs, see also [Issues with specific GPUs or GPU drivers](#issues-with-specific-gpus-or-gpu-drivers). * CUDA is a GPU backend specific to NVIDIA GPUs (it will not work with AMD or Intel or any other GPUs) and requires installing [CUDA](https://developer.nvidia.com/cuda-zone) and [CUDNN](https://developer.nvidia.com/cudnn) and a modern NVIDIA GPU. On most GPUs, the OpenCL implementation will actually beat NVIDIA's own CUDA/CUDNN at performance. The exception is for top-end NVIDIA GPUs that support FP16 and tensor cores, in which case sometimes one is better and sometimes the other is better. * TensorRT is similar to CUDA, but only uses NVIDIA's TensorRT framework to run the neural network with more optimized kernels. For modern NVIDIA GPUs, it should work whenever CUDA does and will usually be faster than CUDA or any other backend. * ROCm is a GPU backend specific to AMD GPUs (it will not work with NVIDIA or Intel or any other GPUs) and requires installing [ROCm](https://rocm.docs.amd.com) and [MIOpen](https://rocm.docs.amd.com/projects/MIOpen) and a modern AMD GPU. Supports both **Linux** (via official ROCm packages, ROCm 6.4+) and **Windows** (via [AMD TheRock](https://github.com/ROCm/TheRock) builds). On most GPUs, the OpenCL implementation will actually beat AMD's own ROCm/MIOpen at performance. The exception is for top-end AMD GPUs that support FP16 and stream processors, in which case sometimes one is better and sometimes the other is better. - * MIGraphX is an alternative GPU backend for AMD GPUs using AMD's MIGraphX graph-compiler framework instead of MIOpen. It compiles the entire neural network into a single fused GPU program, which can offer better throughput than ROCm/MIOpen on some workloads. Requires ROCm 7.0+ with MIGraphX installed. Currently supports Linux only. * Eigen is a *CPU* backend that should work widely *without* needing a GPU or fancy drivers. Use this if you don't have a good GPU or really any GPU at all. It will be quite significantly slower than OpenCL or CUDA, but on a good CPU can still often get 10 to 20 playouts per second if using the smaller (15 or 20) block neural nets. Eigen can also be compiled with AVX2 and FMA support, which can provide a big performance boost for Intel and AMD CPUs from the last few years. However, it will not run at all on older CPUs (and possibly even some recent but low-power modern CPUs) that don't support these fancy vector instructions. For **any** implementation, it's recommended that you also tune the number of threads used if you care about optimal performance, as it can make a factor of 2-3 difference in the speed. See "Tuning for Performance" below. However, if you mostly just want to get it working, then the default untuned settings should also be still reasonable. @@ -183,8 +181,7 @@ This section summarizes a number of common questions and issues when running Kat #### Issues with specific GPUs or GPU drivers If you are observing any crashes in KataGo while attempting to run the benchmark or the program itself, and you have one of the below GPUs, then this is likely the reason. -* **AMD GPUs** - If you choose to use the ROCm backend, you need a GPU on the official [System requirements list](https://rocm.docs.amd.com/projects/install-on-linux/en/latest/reference/system-requirements.html) (at least AMD Radeon RX 7700 XT).

This is the most general GPU version of KataGo and doesn't require a complicated install like CUDA does, so is most likely to work out of the box as long as you have a fairly modern GPU. **However, it also need to take some time when run for the very first time to tune itself.** For many systems, this will take 5-30 seconds, but on a few older/slower systems, may take many minutes or longer. Also, the quality of OpenCL implementations is sometimes inconsistent, particularly for Intel Integrated Graphics and for AMD GPUs that are older than several years, so it might not work for very old machines, as well as specific buggy newer AMD GPUs, see also [Issues with specific GPUs or GPU drivers](#issues-with-specific-gpus-or-gpu-drivers). * CUDA is a GPU backend specific to NVIDIA GPUs (it will not work with AMD or Intel or any other GPUs) and requires installing [CUDA](https://developer.nvidia.com/cuda-zone) and [CUDNN](https://developer.nvidia.com/cudnn) and a modern NVIDIA GPU. On most GPUs, the OpenCL implementation will actually beat NVIDIA's own CUDA/CUDNN at performance. The exception is for top-end NVIDIA GPUs that support FP16 and tensor cores, in which case sometimes one is better and sometimes the other is better. * TensorRT is similar to CUDA, but only uses NVIDIA's TensorRT framework to run the neural network with more optimized kernels. For modern NVIDIA GPUs, it should work whenever CUDA does and will usually be faster than CUDA or any other backend. - * ROCm is a GPU backend specific to AMD GPUs (it will not work with NVIDIA or Intel or any other GPUs) and requires installing [ROCm](https://rocm.docs.amd.com) and [MIOpen](https://rocm.docs.amd.com/projects/MIOpen) and a modern AMD GPU. Supports both **Linux** (via official ROCm packages, ROCm 6.4+) and **Windows** (via [AMD TheRock](https://github.com/ROCm/TheRock) builds). On most GPUs, the OpenCL implementation will actually beat AMD's own ROCm/MIOpen at performance.

The exception is for top-end AMD GPUs that support FP16 and stream processors, in which case sometimes one is better and sometimes the other is better. Transformer/attention-based neural nets (model version 17+) are supported on all AMD GPUs, and get an additional fused-attention speedup on CDNA and RDNA3/RDNA3.5/RDNA4 GPUs when AMD's Composable Kernel library is also installed (see [Compiling.md](Compiling.md)). * Eigen is a *CPU* backend that should work widely *without* needing a GPU or fancy drivers. Use this if you don't have a good GPU or really any GPU at all. It will be quite significantly slower than OpenCL or CUDA, but on a good CPU can still often get 10 to 20 playouts per second if using the smaller (15 or 20) block neural nets. Eigen can also be compiled with AVX2 and FMA support, which can provide a big performance boost for Intel and AMD CPUs from the last few years. However, it will not run at all on older CPUs (and possibly even some recent but low-power modern CPUs) that don't support these fancy vector instructions. For **any** implementation, it's recommended that you also tune the number of threads used if you care about optimal performance, as it can make a factor of 2-3 difference in the speed. See "Tuning for Performance" below. However, if you mostly just want to get it working, then the default untuned settings should also be still reasonable. diff --git a/cpp/CMakeLists.txt b/cpp/CMakeLists.txt index 4ea8dc7404..874fcf7862 100644 --- a/cpp/CMakeLists.txt +++ b/cpp/CMakeLists.txt @@ -2,14 +2,22 @@ cmake_minimum_required(VERSION 3.18.2) # Helper: produce the default broad list of AMD GPU architectures the ROCm # backend should target when the user has not passed -DCMAKE_HIP_ARCHITECTURES=... -# Required archs are always included; optional archs are probed and only -# included if the HIP compiler accepts them (e.g. older toolchains may not -# support gfx1031/gfx1032). +# Required archs are always included (well-established across many ROCm releases); optional archs +# are probed via an actual compile test and only included if the installed toolchain accepts them - +# this covers newer/rarer archs (RDNA1, RDNA2 sub-variants, RDNA3.5, RDNA4, ...) without hard-failing +# the whole build on an older toolchain that doesn't know about them yet.

Copied unmodified. +- `generated/`: kernel instantiations produced by CK's `generate.py` codegen script, narrowed to + exactly what KataGo needs (see regeneration command below). `fmha_fwd_api.cpp` is the dispatcher + (`fmha_fwd()`); the rest are individual `fmha_fwd_` template instantiations it calls into. + +## Scope (matches what the CUDA backend's cudnn-frontend SDPA path actually uses) + +- fp16 only (CUDA's fused SDPA path is FP16-only too; FP32 always uses the plain kernel fallback) +- batch mode only (no group/variable-length mode) +- bias: no-bias or elementwise (matches the [B,1,S,S] additive mask-derived bias KataGo builds); + no alibi +- mask: none (KataGo has no causal masking; padding is handled via the elementwise bias instead) +- no LSE output, no dropout, no quantization scaling, no attention sink +- hdim buckets: 32, 64 (covers KataGo's (qHeadDim, vHeadDim) combos of 32/32, 32/16, 64/64, 64/32, + 32/64 — smaller actual head dims like 16 are handled via CK's own padding within the 32 bucket) +- targets: gfx9, gfx950, gfx11, gfx115, gfx12 (as of `therock-7.13`; CK has no FMHA codegen support + for gfx10/RDNA2 — gfx1030/1031/1032 always use the plain kernel fallback. gfx125 doesn't exist as + a target in this codegen version either.) + +## Regenerating + +From a checkout of `projects/composablekernel/example/ck_tile/01_fmha/` at tag `therock-7.13` in the +CK source repo: + +``` +python3 generate.py --output_dir --targets gfx9,gfx950,gfx11,gfx115,gfx12 -a fwd \ + -f "*_fp16_batch_*_nlogits_*bias_nmask_nlse_ndropout_nskip_nqscale_*nsink" \ + --optdim 32,64 --receipt 0 -m simplified +``` diff --git a/cpp/external/composable_kernel_fmha/bias.hpp b/cpp/external/composable_kernel_fmha/bias.hpp new file mode 100644 index 0000000000..b526204384 --- /dev/null +++ b/cpp/external/composable_kernel_fmha/bias.hpp @@ -0,0 +1,114 @@ +// Copyright (c) Advanced Micro Devices, Inc., or its affiliates. +// SPDX-License-Identifier: MIT + +#pragma once + +#include +#include +#include "ck_tile/core.hpp" +#include "ck_tile/ops/fmha.hpp" + +// keep sync with BlockAttentionBiasEnum +enum class bias_enum +{ + no_bias = 0, + elementwise_bias = 1, + alibi = 2, +};
