Hi again

I have a new question about gpu

I’m working in a server with 4 cards to run my apps, but later of some time I can’t run nothing because every time that I make a call to cudaMalloc the application stays blocked.

Can pass hours, but the app stay blocked trying to reserve memory.

I know that is not problem of my app because if I launch other little apps these dont work too.

Somebody has get the same or similar problem?
And how can I solve this problem?

Thanks in advance
Best regards

Hello guys

When I try to run the code, I get the error “Error del bus”.

Since then, I can’t execute other apps.

thanks

Are your home directories on NFS by chance? Try setting the environment variable CUDA_CACHE_DISABLE=1 before executing your program. On NFS home dirs, the caching mechanism can sometimes wait forever in an infinite loop waiting for a file lock.
