Download E-books Programming Massively Parallel Processors: A Hands-on Approach (Applications of GPU Computing Series) PDF

Programming hugely Parallel Processors discusses uncomplicated techniques approximately parallel programming and GPU structure. ""Massively parallel"" refers back to the use of a giant variety of processors to accomplish a suite of computations in a coordinated parallel means. The publication info a number of recommendations for developing parallel courses. It additionally discusses the advance method, functionality point, floating-point structure, parallel styles, and dynamic parallelism. The e-book serves as a instructing advisor the place parallel programming is the most subject of the path. It builds at the fundamentals of C programming for CUDA, a parallel programming surroundings that's supported on NVI- DIA GPUs.
Composed of 12 chapters, the e-book starts off with uncomplicated information regarding the GPU as a parallel laptop resource. It additionally explains the most techniques of CUDA, information parallelism, and the significance of reminiscence entry potency utilizing CUDA.
The target market of the publication is graduate and undergraduate scholars from all technology and engineering disciplines who desire information regarding computational considering and parallel programming.

  • Teaches computational pondering and problem-solving recommendations that facilitate high-performance parallel computing.
  • Utilizes CUDA (Compute Unified machine Architecture), NVIDIA's software program improvement software created in particular for hugely parallel environments.
