cuobjdump

Accelerated Computing CUDA CUDA Programming and Performance

Hi,
I’m trying to use cuobjdump on a XXX.compute_20.cubin file the command I use is:
cuobjdump.exe XXX.compute_20.cubin // ( or any other [option] values )

The exe runs and doesnt give any error but I dont see any output on the screen nor a file on disk…
Am using Windows XP 64 bit. Any ideas?

EDIT: same happens (or doesn’t happen :) ) in linux.

thanks
eyal

cuobjdump only works on compute_1x

This also doesnt return anything…

./cuobjdump -cubin GGPUGenericEngine.compute_13.cubin

use -sass

For me sass is working fine and giving me assembly instructions.

But what if I want I want PTX from a sm_13 cubin?

./cuobjdump -sass XXX.sm_13.cubin
Works fine and prints out assembly

./cuobjdump -ptx XXX.sm_13.cubin
It prints out the cubin itself.

there’s no PTX in a cubin.

I’m sorry, I thought it would work like decuda…

What does the -ptx option do?

The “cuobjdump -ptx program” is not working, but -sass can see the output on the screen. I am using cuda 7.0 on K40c, compiling the program with sm_35. Any ideas?

Not working how? What are the symptoms? What are the exact command line switches passed to nvcc during compilation? You may be compiling with compiler switches that cause only SASS (machine code) but not PTX to be emitted into the object file.
