copyin Memcpy FAILED:63

Hello, Dear All,

I got this error. What does it mean, please?

copyin Memcpy FAILED:63

Hi happyfish,

It means the host to device copy failed for some reason. Error 63 is the code for cudaErrorOperatingSystem, meaning a call to an OS routine failed, though I’ve no idea if this is correct, nor why it would occur with your program.
