Just as the title says, I'm learning how to use the GPGPUsim. And when I read the "PTX extraction" section of the manual, I found that it says "In CUDA version 4.0 and later, the fat cubin file used to extract the ptx and sass is not available any more." which makes me confused. How to understand this, what happened in CUDA version 4.0 and later. Thank you anyway :)

When CUDA 4.0 was released (in 2011!), the device toolchain was switched to a fully ELF based object model. Prior to that, a plain text file with encoded binary sections for emitted SASS code and plain text for PTX was used. As a result, to extract PTX or SASS from an ELF CUDA object requires a utility cuobjdump to access the requisite code.
Thus the pre/post CUDA 4.0 distinction.
