You can use the CUDA Samples from NVIDIA to learn and test CUDA Toolkit 12.9 features by downloading them from GitHub or as a ZIP file. These samples show how to use CUDA for GPU programming, including utilities, concepts, libraries, and performance optimization. You build them with CMake on Linux, Windows, or Tegra devices, and can run tests automatically with a provided Python script. This helps you understand CUDA programming, debug GPU code, and optimize your applications for better performance on NVIDIA GPUs. It’s a practical way to develop and improve GPU-accelerated software efficiently.

跳进Passacaglia的兔子洞(1)——什么是 Passacaglia?
前些天在广播里听到了交响乐版的 Bach 的Passacaglia and Fugue in C minor,于是略微跳进了兔子洞🤣了解了一下Passacaglia这个形制,Bach的这一首Passacaglia以及管风琴的一些知识~
先是了解了一下 Passacaglia 这个形制。Passacaglia 是17世纪在西班牙起源的,这个词本身的意思大约就是 cross(passa) caglia(street)。最大的特点是有一个bass-ostinato,然后在这个基础上写很多旋律variation。一般 Passacaglia 都是三拍子的,而且有一种比较严肃的感觉。这个形制和 Chaconne 非常类似,后面也会被音乐家混合使用。
除了巴赫的这首著名的 Passacaglia and Fugue in C minor 之外,其他比较有名的 Passacaglia 还有 Handel 的 Harpsichord Suite No. VII in G minor (HWV 432)最后一个乐章, Purcell 的歌剧Dido and Aeneas 中的 Dido’s Lament,Mendelssohn 也写过一首管风琴的 Passacaglia in C minor (不愧是巴赫复兴鼻祖?😂),还有肖斯塔科维奇的 Lady Macbeth of Mtsensk Act 2 的 interlude (也有一个管风琴版本)。
扯了这么多,还是先分享一下拉我进兔子洞的罪魁祸首吧,由Leopold Stokowski改编的交响乐版 Bach: Passacaglia And Fugue In C Minor, BWV 582~
