Memory cuda memcheck输出的函数名跟踪

Memory cuda memcheck输出的函数名跟踪,memory,cuda,gpu,memcheck,Memory,Cuda,Gpu,Memcheck,我运行到cudamemcheck调试我的代码,输出如下 ========= Program hit cudaErrorCudartUnloading (error 29) due to "driver shutting down" on CUDA API call to cudaFree. ========= Saved host backtrace up to driver entry point at error ========= Host Frame:/usr/lib/

我运行到
cudamemcheck
调试我的代码,输出如下

========= Program hit cudaErrorCudartUnloading (error 29) due to "driver shutting down" on CUDA API call to cudaFree. 
=========     Saved host backtrace up to driver entry point at error

是否可以从行
主机帧:./nmt[0x53526]
判断代码中哪里断开?如果是,我该怎么做

谢谢。

正如@Talonmes所指出的(我想他不会介意我发布CW答案),
cuda memcheck
工具提供了额外的堆栈回溯跟踪功能,可以在命令行中添加
--show backtrace
开关来启用该功能

回溯可包括主机和设备功能(即主机和设备回溯)

如果还使用主机调试符号信息编译了应用程序(例如linux上的
-g
),则
cuda memcheck
可以在主机回溯中显示主机函数的函数名


更多使用信息可在中找到。

这是一个很好的资源。谢谢@Talonmies是的,如果有疑问,请阅读文档
