cuda-gdb error


I’m trying to debug a simple CUDA application on a remote machine via ssh.

After I set the breakpoint, I try to run or step through the program and I receive the following error:

Error: Failed to read the valid lanes mask (dev=0, sm=0, wp=0, error=13).

What this error means ? How can I fix it ?

Thank You

Also, try using the latest 4.0 toolkit, quite a few such bugs were fixed in the 4.0 release:
