nsight 虽然比较新,但是因为各个功能分布在不同的子命令里,似乎反而不是那么容易上手。例如要测各个 kernel 的执行时间要用一种子命令;要分析 GPU 上的硬件指标又要用另一种子命令,并且还要用另外的命令打开分析结果。如果有比较简洁的 nsight 教程,欢迎分享。@xxcclong 有何建议?
Sorry, something went wrong.
NVIDIA 计算能力7.5及以上的GPU设备不再支持nvprof工具进行性能剖析,提示使用Nsight Compute作为替代品,如下图所示

实验平台用的 GPU 是 P100,Compute Capability 是 6.0,可以用 nvprof。我个人觉得本课程的目标不是教如何使用具体的软件:如果 nsight 确实更好用,可以改教 nsight;但如果用 nsight 只是为了兼容特定硬件,就不太有必要了。如果你要用 T4 或者 A100 的话,可以参照 nsight 的文档使用,其中的原理是一样的,只是命令不一样。另外, A100 甚至没法在中国买到了。
