The source of a 1.x release was made available to registered developers a while ago. Nothing more recent.
No cublas is not combined with the SDK.
cublas is supplied in the CUDA toolkit, and the version you have is always the same as the toolkit you are building with and linking against. If you are using cuda 3.2, you are using cublas 3.2.
I have to revive this post after many years. I try to obtain source code of cuBLAS.
I did register on NVIDIA site as a developer, but I still cannot find where to get the source code.
Can someone direct me? Thank you so much in advance!
Furthermore, much of it is written in SASS and not cuda, so it’s not very useful for most people outside of nvidia. You could try to disassemble and understand the code, though, as Scott gray has done.
