Caches[ edit ] Historically, CPUs have used hardware-managed caches but the earlier GPUs only provided software-managed local memories. However, as GPUs are being increasingly used for general-purpose applications, state-of-the-art GPUs are being designed with hardware-managed multi-level caches  which have helped the GPUs to move towards mainstream computing.
Register file[ edit ] GPUs have very large register files, which allow them to reduce context-switching latency. Register file size is also increasing over different GPU generations, e. Due to their design, GPUs are only effective for problems that can be solved using stream processing and the hardware can only be used in certain ways.
See e. This is especially effective when the programmer wants to process many vertices or fragments in the same way. A stream is simply a set of records that require similar computation.

Streams provide data parallelism. Kernels are the functions that are applied to each element in the stream. In the GPUs, vertices and fragments are the elements in streams and vertex and fragment shaders are the kernels to be run on them. It is permissible to have multiple inputs and multiple outputs, but never a piece of memory that is both readable and writable. It is important for GPGPU applications to have high arithmetic intensity else the memory access latency will limit computational speedup.
GPU programming concepts[ edit ] Computational resources[ edit ] There are a variety of computational resources available on the GPU: Programmable processors — vertex, primitive, fragment and mainly compute pipelines allow programmer to perform kernel on streams of data Rasterizer — creates fragments and interpolates per-vertex constants such as texture coordinates and color Texture unit — read-only memory interface Framebuffer — write-only memory interface In fact, a program can substitute a write only texture for output instead of the framebuffer.
Many computations naturally map into grids: matrix algebra, image processing, physically based simulation, and so on. Since textures are used as memory, texture lookups are then used as memory reads. Certain operations can be done automatically by the GPU because of this.
Kernels[ edit ] Compute kernels can be thought of as the body of loops. Flow control[ edit ] In sequential code it is possible to control the flow of the program using if-then-else statements and various forms of loops.
Such flow control structures have only recently been added to GPUs. Recent GPUs allow branching, but usually with a performance penalty. Branching should generally be avoided in inner loops, whether in CPU or GPU code, and various methods, such as static branch resolution, pre-computation, predication, loop splitting,  and Z-cull  can be used to achieve branching when hardware support does not exist.
Be sure to check for other copies, because there may be other editions available. Software engineers, programmers, hardware engineers, and compuhing students pef find this book extremely usefull. Clicking on the 'download It Now' link will cause you to leave the library download platform website.

Divided into five sections, the book explains how GPU execution is achieved with algorithm implementation techniques and approaches to data structure layout.
There are also discussions on the state of GPU computing in interactive physics and artificial intelligence; programming tools and techniques for GPU computing; computung the edge and node parallelism approach for computing graph centrality metrics. Jzde addition, the book proposes an alternative approach that balances computation regardless of node degree variance.

Data are also kept on e. GPUs as long as they are needed for further tasks.
StarPU also takes care of automatically prefetching data, which thus permits to overlap data transfers with computations including GPU-GPU direct transfers to achieve the most of the architecture. It also supports a commute access mode to allow data access commutativity new in v1. It also supports transparent dependencies tracking between hierarchical subpieces of data through asynchronous partitioning new in v1.
Heterogeneous Scheduling StarPU obtains portable performances by efficiently and easily using all computing resources at the same time.
StarPU also takes advantage of the heterogeneous nature of a machine, for instance by using scheduling strategies based on auto-tuned performance models. These determine the relative performance achieved by the different processing units for the various kinds of task, and thus permits to automatically let processing units execute the tasks they are the best for.
Various strategies and variants are available. Some of them are centralized, but most of them are completely distributed.You have already checked out this title. In case a codelet can run on heterogeneous architectures, it is possible to specify one function for each architectures e.
