cuda-gdb: where is my block?

Hi,

Using cuda-gdb,
I set a breakpoint and I need to set focus to, say, block(X,Y).
When debugger hits the breakpoint, it focuses on a SM which might not (usually does not)
contain the block I am interested in.

How do I find out quickly (i.e. not changing focus to all different SM and see) where my block is?

Cheers
