[CUDA] Download instead of having the user install it. by Neumann-A · Pull Request #35336 · microsoft/vcpkg

(Only tested with windows currently.)

Tested the installation of cub:x64-windows on a machine without CUDA installed (it depends on CUDA), and cub can be successfully installed.

I am concerned that by effectively creating our own CUDA distribution that isn't identical to real CUDA (with CUDA_HOME and all that stuff) that this behavior is likely to be ... 'surprising'.

Also, this copies stuff from CUDA into the installed tree; I'm not sure that's desirable.

(I'm not 'request changes' here because these are closer to 'questions' than 'this needs to change')

+set(components


Where did these lists come from?

Asking this questions 5 months after the fact is a bit hard. But probably just open https://developer.download.nvidia.com/compute/cuda/redist/ in a web browser + look at the redistrib_x.y.z.json files there and also checking conda-forge recipes.

My understanding is that nsight is some kind of developer gui tool so its OK that it isn't included here, but it does highlight a concern: If folks were using vcpkg with something nsight, before they were getting the matching bits for their copy of CUDA, now they might get mismatched bits. Do we have folks who actually use cuda regularly to common on the practicality of this idea?

Nobody stops you from installing the exact same version of cuda vcpkg would install. (If it even matters. From my understanding Nsight is basically a profiler like vtune to figure out bottlenecks. )

Unfortunately I think this implicates the tool ports thing since this is going to try to provide nvcc...

It is not trying to provide nvcc it is providing nvcc. (but you could also use the installation with clang to compile cuda)

+  # Don't really know why this renaming is required. 
+  file(RENAME "${CURRENT_PACKAGES_DIR}/tools/cuda/lib" "${CURRENT_PACKAGES_DIR}/tools/cuda/lib64")


In general lib vs. lib64 depends on one's distro...

tuned to what nvcc expects.

+    #string(REGEX REPLACE "/targets/x86_64-linux" "" contents "${contents}")


There's a lot of commented out code in here; are you still working on this?

Hmm below 5% lines are comments in this file is considered a lot?
I probably expected this to be needed to be changed but there was no pc file consumer for cuda yet so it couldn't be properly tested.

+set(VCPKG_POLICY_EMPTY_INCLUDE_FOLDER enabled)


CUDA has headers so if you need this skip it seems like something is wrong? I would get this if it only made bits pointing to a separate cuda install somewhere, but it isn't doing that.

headers are not located in /include but /tools/cuda/... (whatever nvcc expects)

@data-queue @ras0219-msft @vicroms @JavierMatosD and I discussed this today and we are not blocking over $CUDA_HOME not being exactly the official layout. I still need to review this overall.

I think there needs to be a description in this port describing the differences between how it installs things and how things are in a 'CUDA_HOME'.

Neumann-A · 2024-03-11T21:52:27Z

tools/cuda should have the same layout as CUDA_HOME since otherwise the compiler does not work. libs and dlls are also copied to (debug)?/bin (debug)?/lib for vcpkg to deploy the dlls and making it easier for cmake or other buildsystems to find the libs.

Can you describe this in a comment in the port?

One issue here is that the license files seem to change over time.

BillyONeal · 2024-06-13T19:53:50Z

It looks like they stopped with the 'sign one's life away' to download cudnn; https://developer.download.nvidia.com/compute/cudnn/redist/cudnn/windows-x86_64/cudnn-windows-x86_64-9.2.0.82_cuda12-archive.zip looks like a normal URI now.

Cracking open the installer directly seems pseudo-blessed by nvidia now

BillyONeal · 2024-06-14T22:12:17Z

(I'm just observing changes relevant to this review as I'm updating the build lab to CUDA 12.5, sorry for the spam)
