Hanrahan 教授（2019 年图灵奖得主）的指导下开展如何方便且高效发挥 GPU 能力的研究。2004 年，Buck 发表 了一篇题为“Brook for GPUs:Stream Computing on Graphics Hardware”的论文[17]， 为 GPU 设计了一套支持流编程（Stream Programming）语言的编译器和运行时系统 Brook，从而能让开发者像在通用 算机。2007 年，国防科大杨学 军院士带领团队在国际计算机体系结构旗舰会议 ISCA 上发表题为“A 64-bit stream processor architecture for scientific applications”的学术论文[19]，揭示了流处理器架构 可大幅加速科学计算。这项工作不仅为具备大量流处理器的 GPU 开辟了新应用场景，也为超 级计算机架构设计开辟一条新技术 Reiter Horn, Jeremy Sugerman, Kayvon Fatahalian, Mike Houston, Pat Hanrahan, Brook for GPUs: stream computing on graphics hardware.

parallel programming: 1. Asynchronous ”tasks”, or coroutines 2. Multi-threading 3. Distributed computing Julia Tasks allow suspending and resuming computations for I/O, event handling, producer-consumer run simultaneously on more than one thread or CPU core, sharing memory. Finally, distributed computing runs multiple processes with separate memory spaces, potentially on different machines. This functionality [-2.7, 1.3, 3.1, 4.4]. Note that Julia takes care of converting the array to a Ptr{Cdouble}), computing the size of the element type in bytes, and so on. 25.2. MAPPING C TYPES TO JULIA 257 For fun

ms (milliseconds), us (microseconds), or ns (nanoseconds): 140.884ms , 500us , 24ns . Scientific notation is no longer used to represent them. If you want to express duration in a single unit Kotlin, use sequences. Multi-step processing of sequences is executed lazily when possible – actual computing happens only when the result of the whole processing chain is requested. fun main() { //sampleStart //sampleStart val a = async { log("I'm computing a piece of the answer") 6 } val b = async { log("I'm computing another piece of the answer") 7 }

hoped to bring professional level 3D modeling and animation tools within the reach of the general computing public. NaN’s business model involved providing commercial products and services around Blender to do things with selected nodes. Use Nodes Tells the render engine to use the node tree when computing the material color or rendering the final image, or not. If not, the tree is ignored. For materials Blender computes small images (like thumbnails) for the big images and may take some time. After computing them, though, editing functions like scrubbing and scrolling is much faster but gives a low-res
