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).
