··· 1 1 # Modules 2 2 3 - Modules as they are used in `modules` exist primarily to check the shape and content of CUDA redistributable and feature manifests. They are ultimately meant to reduce the repetitive nature of repackaging CUDA redistributables. 3 + Modules as they are used in `modules` exist primarily to check the shape and 4 + content of CUDA redistributable and feature manifests. They are ultimately meant 5 + to reduce the repetitive nature of repackaging CUDA redistributables. 4 6 5 - Building most redistributables follows a pattern of a manifest indicating which packages are available at a location, their versions, and their hashes. To avoid creating builders for each and every derivation, modules serve as a way for us to use a single `genericManifestBuilder` to build all redistributables. 7 + Building most redistributables follows a pattern of a manifest indicating which 8 + packages are available at a location, their versions, and their hashes. To avoid 9 + creating builders for each and every derivation, modules serve as a way for us 10 + to use a single `genericManifestBuilder` to build all redistributables. 6 11 7 12 ## `generic` 8 13 9 - The modules in `generic` are reusable components meant to check the shape and content of NVIDIA's CUDA redistributable manifests, our feature manifests (which are derived from NVIDIA's manifests), or hand-crafted Nix expressions describing available packages. They are used by the `genericManifestBuilder` to build CUDA redistributables. 14 + The modules in `generic` are reusable components meant to check the shape and 15 + content of NVIDIA's CUDA redistributable manifests, our feature manifests (which 16 + are derived from NVIDIA's manifests), or hand-crafted Nix expressions describing 17 + available packages. They are used by the `genericManifestBuilder` to build CUDA 18 + redistributables. 10 19 11 - Generally, each package which relies on manifests or Nix release expressions will create an alias to the relevant generic module. For example, the [module for CUDNN](./cudnn/default.nix) aliases the generic module for release expressions, while the [module for CUDA redistributables](./cuda/default.nix) aliases the generic module for manifests. 20 + Generally, each package which relies on manifests or Nix release expressions 21 + will create an alias to the relevant generic module. For example, the [module 22 + for CUDNN](./cudnn/default.nix) aliases the generic module for release 23 + expressions, while the [module for CUDA redistributables](./cuda/default.nix) 24 + aliases the generic module for manifests. 12 25 13 - Alternatively, additional fields or values may need to be configured to account for the particulars of a package. For example, while the release expressions for [CUDNN](./cudnn/releases.nix) and [TensorRT](./tensorrt/releases.nix) are very close, they differ slightly in the fields they have. The [module for CUDNN](./modules/cudnn/default.nix) is able to use the generic module for release expressions, while the [module for TensorRT](./modules/tensorrt/default.nix) must add additional fields to the generic module. 26 + Alternatively, additional fields or values may need to be configured to account 27 + for the particulars of a package.

These expressions are created when NVIDIA-provided manifests are unavailable or otherwise unusable. For example, though CUDNN has manifests, a bug in NVIDIA's CI/CD causes manifests for different versions of CUDA to use the same name, which leads to the manifests overwriting each other. 46 + The modules in `generic/releases` define the structure of our hand-crafted Nix 47 + expressions containing information necessary to download and repackage CUDA 48 + redistributables.
