针对你提出的“cuda error: named symbol not found cuda kernel errors might be asynchronous”问题,以下是一些可能的解决方案和排查步骤: 确认CUDA环境配置正确: 确保你的系统上安装了正确的CUDA Toolkit。 检查环境变量如PATH和LD_LIBRARY_PATH是否包含了CUDA的路径。

kernel errors might be asynchronously reported at some other API call,so the stacktrace below might be incorrect. For debugging consider passing CUDA_LAUNCH_BLOCKING=1. Exception raised from create_event_internal at ../c10/cuda/CUDACachingAllocator.cpp:1055 (most recent call first): frame #0: ...

Certain classes of hardware errors This leaves the process in an inconsistent state and any further CUDA work will return the same error. To continue using CUDA, the process must be terminated and relaunched. cudaErrorInvalidSource = 300 This indicates that the device kernel source is invalid....
Kernel errors are sticky errors and cannot be recovered. What about cudaMemcpyAsync()? I assume since “all asynchronous errors are sticky” it is a sticky error as well. Does a sticky error discards all operations queued after the failed operation? I have a feeling that it does not, but ...
The first statement can capture the last error before the second statement, and the second statement can synchronize the host and the device. The reason for using a synchronization between host and device is that kernel launching is asynchronous, which means that the host will continue to execute...
One of the optimization strategies to maximize the performance of a GPU kernel is to minimize data transfer. If the memory is resident in global memory, the latency of reading data into the L2 cache or into shared memory might take several hundred processor cycles. ...

In order to enable the attach feature of the CUDA debugger, either cuda-gdb should be launched as root, or /proc/sys/kernel/yama/ptrace_scope should be set to zero, using the following command: $ sudo sh -c "echo 0 >/proc/sys/kernel/yama/ptrace_scope" To make the change permanent,...
