Fortran has been the premier language for scientific computing since its introduction in 1957. Fortran originally was designed to allow programmers to evaluate formulas—FORmula TRANslation—easily on large computers. Fortran compilers are now available on all sizes of machines, from small desktop computers to huge multiprocessors. The Guide to Fortran 2003 Programming is an informal, tutorial introduction to the most important features of Fortran 2003 (also known as Fortran 03), the latest stan

本文描述了语言模型的发展历史，指出未来可能的发展方向。近年来，自然语言处理 (NLP) 领域发生了革命性的变化。由于预训练语言模型的开发和应用，NLP 在许多应用领域取得了显著的成就。预训练语言模型有两个主要优点。一、它们可以显著提高许多自然语言处理任务的准确性。例如，可以利用 BERT 模型来实现比人类更高的语言理解性能。我们还可以利用 GPT-3 模型生成类似人类写的文章。预训练语言模型的第二个优点是它们是通用的语言处理工具。在传统的自然语言处理中，为了执行机器学习任务，必须标记大量数据来训练模型。相比之下，目前只需要标记少量数据来微调预训练语言模型，因为它已经获得了语言处理所需的大量知识。 本文从计算机科学的发展历史和未来趋势的角度简要介绍语言建模，特别是预训练语言模型，对 NLP 领域的基本概念、直观解释、技术成就和面临的挑战展开了综述，为初学者提供了关于预训练语言模型的参考文献。 自然语言处理是计算机科学（CS）、人工智能（AI）和语言学的一个交叉领域，包括机器翻译、阅读理解、对话系统、文本摘要、文本生成等应用。近年来，深度学习已成为自然语言处理的基础技术。 借助数学知识

If you need to learn CUDA but don't have experience with parallel computing, "CUDA Programming: A Developer's Introduction" offers a detailed guide to CUDA with a grounding in parallel fundamentals. It starts by introducing CUDA and bringing you up to speed on GPU parallelism and hardware, then delving into CUDA installation. Chapters on core concepts including threads, blocks, grids, and memory focus on both parallel and CUDA-specific issues. Later, the book demonstrates CUDA in practice for optimizing applications, adjusting to new hardware, and solving common problems. This title offers comprehensive introduction to parallel programming with CUDA, for readers new to both. It includes detailed instructions that help readers optimize the CUDA software development kit. It provides practical techniques that illustrate working with memory, threads, algorithms, resources, and more. It covers CUDA on multiple hardware platforms: Mac, Linux and Windows with several NVIDIA chipsets. Each chapter includes exercises to test reader knowledge.
