'''GPU''' (Graphics Processing Unit),<br/>
a specialized processor primarily initially intended for fast [https://en.wikipedia.org/wiki/Image_processing image processing]. GPUs may have more raw computing power than general purpose [https://en.wikipedia.org/wiki/Central_processing_unit CPUs] but need a specialized and massive parallelized way of programming. [[Leela Chess Zero]] has proven that a [[Best-First|Best-first]] [[Monte-Carlo Tree Search|Monte-Carlo Tree Search]] (MCTS) with [[Deep Learning|deep learning]] methodology will work with GPU architectures.
=History=In the 1970s and 1980s RAM was expensive and Home Computers used custom graphics chips to operate directly on registers/memory without a dedicated frame buffer resp. texture buffer, like [https://en.wikipedia.org/wiki/Television_Interface_Adaptor TIA]in the [[Atari 8-bit|Atari VCS]] gaming system, [https://en.wikipedia.org/wiki/CTIA_and_GTIA GTIA]+[https://en.wikipedia.org/wiki/ANTIC ANTIC] in the [[Atari 8-bit|Atari 400/800]] series, or [https://en.wikipedia.org/wiki/Original_Chip_Set#Denise Denise]+[https://en.wikipedia.org/wiki/Original_Chip_Set#Agnus Agnus] in the [[Amiga|Commodore Amiga]] series. The 1990s would make 3D graphics and 3D modeling more popular, especially for video games. Cards specifically designed to accelerate 3D math, such as [https://en.wikipedia.org/wiki/IMPACT_(computer_graphics) SGI Impact] (1995) in 3D graphics-workstations or [https://en.wikipedia.org/wiki/3dfx#Voodoo_Graphics_PCI 3dfx Voodoo] (1996) for playing 3D games on PCs, emerged. Some game engines could use instead the [[SIMD and SWAR Techniques|SIMD-capabilities]] of CPUs such as the [[Intel]] [[MMX]] instruction set or [[AMD|AMD's]] [[X86#3DNow!|3DNow!]] for [https://en.wikipedia.org/wiki/Real-time_computer_graphics real-time rendering]. Sony's 3D capable chip [https://en.wikipedia.org/wiki/PlayStation_technical_specifications#Graphics_processing_unit_(GPU) GTE] used in the PlayStation (1994) and Nvidia's 2D/3D combi chips like [https://en.wikipedia.org/wiki/NV1 NV1] (1995) coined the term GPU for 3D graphics hardware acceleration. With the advent of the [https://en.wikipedia.org/wiki/Unified_shader_model unified shader architecture], like in Nvidia [https://en.wikipedia.org/wiki/Tesla_(microarchitecture) Tesla] (2006), ATI/AMD [https://en.wikipedia.org/wiki/TeraScale_(microarchitecture) TeraScale] (2007) or Intel [https://en.wikipedia.org/wiki/Intel_GMA#GMA_X3000 GMA X3000] (2006), GPGPUframeworks like [https://en.wikipedia.org/wiki/CUDA CUDA] and [[OpenCL|OpenCL]] emerged and gained in popularity. =GPU in Computer Chess= There are in main four ways how to use a GPU for chess:
== Khronos OpenCL ==

=The Implicitly Parallel SIMD Model=Thread Examples==
===MemoryExamples=== The memory hierarchy of an GPU consists in main of private memory (registers accessed by an single thread resp. work-item), local memory (shared by threads of an block resp. work-items of an work-group ), constant memory, different types of cache and global memory. Size, latency and bandwidth vary between vendors and architectures.
* 128 KiB private memory per compute unit
* 48 KiB (16 KiB) local memory per compute unit (configurable)
* 8 KiB constant cache per compute unit
* 16 KiB (48 KiB) L1 cache per compute unit (configurable)
* 768 KiB L2 cachein total
* 1.5 GiB to 3 GiB global memory
* 256 KiB private memory per compute unit
* 64 KiB local memory per compute unit
* 16 KiB constant cache per four compute units
* 16 KiB L1 cache per compute unit
* 768 KiB L2 cachein total
* 3 GiB to 6 GiB global memory
===Unified Memory===
Usually data has to be copied between a CPU host and a discrete GPU device, but different architectures from different vendors with different frameworks on different operating systems may offer a unified and accessible address space between CPU and GPU.
=Instruction Throughput=
GPUs are used in [https://en.wikipedia.org/wiki/High-performance_computing HPC] environments because of their good [https://en.wikipedia.org/wiki/FLOP FLOP]/Watt ratio. The instruction throughput in general depends on the architecture (like Nvidia's [https://en.wikipedia.org/wiki/Tesla_%28microarchitecture%29 Tesla], [https://en.wikipedia.org/wiki/Fermi_%28microarchitecture%29 Fermi], [https://en.wikipedia.org/wiki/Kepler_%28microarchitecture%29 Kepler], [https://en.wikipedia.org/wiki/Maxwell_%28microarchitecture%29 Maxwell] or AMD's [https://en.wikipedia.org/wiki/TeraScale_%28microarchitecture%29 TerascaleTeraScale], [https://en.wikipedia.org/wiki/Graphics_Core_Next GCN], [https://en.wikipedia.org/wiki/AMD_RDNA_Architecture RDNA]), the brand (like Nvidia [https://en.wikipedia.org/wiki/GeForce GeForce], [https://en.wikipedia.org/wiki/Nvidia_Quadro Quadro], [https://en.wikipedia.org/wiki/Nvidia_Tesla Tesla] or AMD [https://en.wikipedia.org/wiki/Radeon Radeon], [https://en.wikipedia.org/wiki/Radeon_Pro Radeon Pro], [https://en.wikipedia.org/wiki/Radeon_Instinct Radeon Instinct]) and the specific model. ==Integer Instruction Throughput==* INT32: The 32-bit integer performance can be architecture and operation depended less than 32-bit FLOP or 24-bit integer performance. * INT64: In general [https://en.wikipedia.org/wiki/Processor_register registers] and Vector-[https://en.wikipedia.org/wiki/Arithmetic_logic_unit ALUs] of consumer brand GPUs are 32-bit wide and have to emulate 64-bit integer operations.* INT8: Some architectures offer higher throughput with lower precision. They quadruple the INT8 or octuple the INT4 throughput.
* 64 bit Integer PerformanceFP32: Current Consumer GPU [https://en.wikipedia.org/wiki/Processor_register registers] and Vectorperformance is measured usually in single-[https://en.wikipedia.org/wiki/Arithmetic_logic_unit ALUs] are precision (32 -bit wide and have to emulate 64 bit integer operations.<ref>[https://en.wikichip.org/w/images/a/a1/vega-whitepaper.pdf AMD Vega White Paper]</ref> <ref>[https://www.nvidia.com/content/dam/en-zz/Solutions/design-visualization/technologies/turing-architecture/NVIDIA) floating-Turingpoint FMA (fused-Architecturemultiply-Whitepaperadd) throughput.pdf Nvidia Turing White Paper]</ref>

Convolutions can be implemented as a series of matrix-multiplications via Winograd-transformations <ref>[https://talkchess.com/forum3/viewtopic.php?f=7&t=66025&p=743355#p743355 Re: To TPU or not to TPU...] by [[Rémi Coulom]], [[CCC]], December 16, 2017</ref>. Mobile SoCs usually have an dedicated neural network engine as MMAC unit. ==Nvidia TensorCores==: With Nvidia [https://en.wikipedia.org/wiki/Volta_(microarchitecture) Volta] series TensorCores were introduced. They offer FP16xFP16+FP32, matrix-multiplication-accumulate-units, used to accelerate neural networks.<ref>[https://on-demand.gputechconf.com/gtc/2017/presentation/s7798-luke-durant-inside-volta.pdf INSIDE VOLTA]</ref> Turing's 2nd gen TensorCores add FP16, INT8, INT4 optimized computation.<ref>[https://www.anandtech.com/show/13282/nvidia-turing-architecture-deep-dive/6 AnandTech - Nvidia Turing Deep Dive page 6]</ref> Amperes's 3rd gen adds support for BF16, TF32, FP64 and sparsity acceleration.<ref>[https://en.wikipedia.org/wiki/Ampere_(microarchitecture)#Details Wikipedia - Ampere microarchitecture]</ref>Ada Lovelaces's 4th gen adds support for FP8.<ref>[https://en.wikipedia.org/wiki/Ada_Lovelace_(microarchitecture) - Ada Lovelace microarchitecture]</ref> ==AMD Matrix Cores==: AMD released 2020 its server-class [https://www.amd.com/system/files/documents/amd-cdna-whitepaper.pdf CDNA] architecture with Matrix Cores which support MFMA (matrix-fused-multiply-add) operations on various data types like INT8, FP16, BF16, FP32. AMD's CDNA 2 architecture adds FP64 optimized throughput for matrix operations. AMD's RDNA 3 architecture features dedicated AI tensor operation acceleration. AMD's CDNA 3 architecture adds support for FP8 and sparse matrix data (sparsity). ==Intel XMX Cores==: Intel added XMX, Xe Matrix eXtensions, cores to some of the [https://en.wikipedia.org/wiki/Intel_Xe Intel Xe] GPU series, like [https://en.wikipedia.org/wiki/Intel_Arc#Alchemist Arc Alchemist] and [https://www.intel.com/content/www/us/en/products/sku/232876/intel-data-center-gpu-max-1100/specifications.html Intel Data Center GPU Max Series].
=Host-Device Latencies=
One reason GPUs are not used as accelerators for chess engines is the host-device latency, aka. kernel-launch-overhead. Nvidia and AMD have not published official numbers, but in practice there is an a measurable latency for null-kernels of 5 microseconds <ref>[https://devtalk.nvidia.com/default/topic/1047965/cuda-programming-and-performance/host-device-latencies-/post/5318041/#5318041 host-device latencies?] by [[Srdja Matovic]], Nvidia CUDA ZONE, Feb 28, 2019</ref> up to 100s of microseconds <ref>[https://community.amd.com/thread/237337#comment-2902071 host-device latencies?] by [[Srdja Matovic]] AMD Developer Community, Feb 28, 2019</ref>. One solution to overcome this limitation is to couple tasks to batches to be executed in one run <ref>[http://www.talkchess.com/forum3/viewtopic.php?f=7&t=67347#p761239 Re: GPU ANN, how to deal with host-device latencies?] by [[Milos Stanisavljevic]], [[CCC]], May 06, 2018</ref>.
=Deep Learning=
GPUs are much more suited than CPUs to implement and train [[Neural Networks#Convolutional|Convolutional Neural Networks]] (CNN), and were therefore also responsible for the [[Deep Learning|deep learning]] boom, also affecting game playing programs combining CNN with [[Monte-Carlo Tree Search|MCTS]], as pioneered by [[Google]] [[DeepMind|DeepMind's]] [[AlphaGo]] and [[AlphaZero]] entities in [[Go]], [[Shogi]] and [[Chess]] using [https://en.wikipedia.org/wiki/Tensor_processing_unit TPUs], and the open source projects [[Leela Zero]] headed by [[Gian-Carlo Pascutto]] for [[Go]] and its [[Leela Chess Zero]] adaption.
= Architectures =
The market is split into two categories, integrated and discrete GPUs. The first being the most important by quantity, the second by performance. Discrete GPUs are divided as consumer brands for playing 3D games, professional brands for CAD/CGI programs and server brands for big-data and number-crunching workloads. Each brand offering different feature sets in driver, VRAM, or computation abilities.
== AMD ==
AMD line of discrete GPUs is branded as Radeon for consumer, Radeon Pro for professional and Radeon Instinct for server.
