T4卡上运行时出现报错 CUDA error at test_MMult.cpp:110 code=999 "cudaEventSynchronize(stop)",想问一下是什么原因呢

tpoisonooo commented

这个测试用的 3080，应该是编译选项问题。

明天或者更晚吧，我找个 2080ti 跑跑看。最近比较忙 QAQ

cudaErrorUnknown = 999
This indicates that an unknown internal error has occurred.

我用 2080 跑了没啥问题。

那句也没干啥，就是在统计开始结束时间。只能换个卡试试？ 或者检查一下环境？
