C++ 当检测到Cuda API错误时，如何查找程序在何处崩溃：cudaMemcpy返回（0xb）

我正在调试cuda程序，并收到以下警告：

warning: Cuda API error detected: cudaMemcpy returned (0xb)

warning: Cuda API error detected: cudaMemcpy returned (0xb)

warning: Cuda API error detected: cudaGetLastError returned (0xb)

Error in kernel
GPUassert: invalid argument

当我在cuda gdb中键入“where”时，它会显示“无堆栈”

我们应该如何找到我的程序崩溃的地方

在这里找到答案：@第27页

您需要首先：

(cuda-gdb) set cuda api_failures stop

然后，当发生错误时，它将停止：

Cuda API error detected: cudaMemcpy returned (0xb)
(cuda-gdb) where
#0  0x00007fffea6a06d0 in cudbgReportDriverApiError () from       /usr/lib64/nvidia/libcuda.so.1
#1  0x00007fffea6a2c36 in cudbgReportDriverInternalError () from /usr/lib64/nvidia/libcuda.so.1
#2  0x00007fffea6eed93 in cudbgGetAPIVersion () from /usr/lib64/nvidia/libcuda.so.1
