According to licence of NVIDIA CUDA toolkit:
ATTACHMENT A
Redistributable Software
In connection with Section 2.1.2 of this Agreement, the following files
may
be redistributed with software applications developed by Licensee,
including variations of these files that have version number
information
embedded in the file name.
Component Windows MacOS Linux
CUDA Runtime cudart.dll libcudart.dylib libcudart.so
libtlshook.dylib
CUDA FFT Library cufft.dll libcufft.dylib libcufft.so
CUDA BLAS Library cublas.dll libcublas.dylib libcublas.so
Those are libraries that you can distribute without any problems.
There is also "Linux clause":
2.1.3 Linux/FreeBSD Exception. Notwithstanding the foregoing terms of
Section 2.1.1, SOFTWARE designed exclusively for use on the Linux or
FreeBSD operating systems, or other operating systems derived from the
source code to these operating systems, may be copied and
redistributed,
provided that the binary files thereof are not modified in any way
(except
for unzipping of compressed files).
So if your programs is to be run only on Linux, you should be able
to distribute large parts of CUDA. But:
1. I am not a lawyer - consult one before trying it.
2. This is rather intended for distribution which want to include
NVIDIA CUDA packages in them. I am not sure how it would be looked
at by real lawyers with copyright experience.
3. It limits you to Linux/BSD.
So IMO better follow Andreas' advice and look at OpenCL - especially
as there is PyOpenCL.
Regards.
