说明：  CUDA Fortran程序设计 此书是面向开发或维护fortran中的计算机模拟和应用或者是想利用GPUs的并行处理能力处理单元（GPU）来加速运行代码的科学家和工程师。这本书的目的是利用CUDA Fortran以及一些典型的例子向读者提供GPU编程的基础，而不必使读者实质上将开发CUDA Fortran代码作为一项任务。
(CUDA Fortran for Scientists and Engineers This document is intended for scientists and engineers who develop or maintain computer simulations and applications in Fortran and who would like to harness the parallel processing power of graphics processing units (GPUs) to accelerate their code. The goal here is to provide the reader with the fundamentals of GPU programming using CUDA Fortran as well as some typical examples, without having the task of developing CUDA Fortran code become an end in itself.)
