NVTX 与 Compute Sanitizer 的第一个示例是suballocation,它是 NVTX Memory API 的一部分。 通过API 可以将内存分配标记为内存池。Compute Sanitizer 了解这些池,并可以检测实际正在使用特定分配的哪些部分。然后,如果在代码执行期间访问了内存池的任何未注册部分,Compute Sanitizer 通过其 `memcheck` 工具来检测这些访问。

然后,我们可以运行之前提到的Python程序来确认CUDA是否可用。在终端中执行以下命令: python cuda_check.py 1. 程序的输出应该类似于以下内容: CUDA device is available: True CUDA device name: /device:GPU:0 1. 2. 这表明CUDA设备可用且名称为/device:GPU:0。

The initcheck tool can report cases where the GPU performs uninitialized accesses to global memory. The synccheck tool can report cases where the application is attempting invalid usages of synchronization primitives. This document describes the usage of these tools. CUDA-MEMCHECK can be run in ...
