CUDA compatibility and PTX⚓︎
The CUDA compatibility documentation denotes the following issue with PTX and minor version compatibility:
Applications that compile device code to PTX will not work on older drivers. If the application requires PTX then administrators have to upgrade the installed driver. [...]
Several applications perform JIT compilation of device code to PTX, and this limitation is problematic when old drivers are installed on a system.
Forward compatibility is mainly intended to support applications built on newer CUDA Toolkits to run on systems installed with an older NVIDIA Linux GPU driver from different major release families. However, it also allows JIT compilation to PTX on older drivers.
Installing forward compatibility package
Download and extract a CUDA driver supporting the target CUDA version:
wget https://us.download.nvidia.com/tesla/575.57.08/NVIDIA-Linux-aarch64-575.57.08.run
bash NVIDIA-Linux-aarch64-575.57.08.run -x
Files will be extracted in NVIDIA-Linux-aarch64-575.57.08.
Copy the following files from the extracted folder into a separate folder
(ssay compat-cu129) and create the appropriate symlinks
mkdir compat-cuda128
cp NVIDIA-Linux-aarch64-575.57.08/libcudadebugger.so.575.57.08 compat-cuda129/
cp NVIDIA-Linux-aarch64-575.57.08/libcuda.so.575.57.08 compat-cuda129/
cp NVIDIA-Linux-aarch64-575.57.08/libnvidia-nvvm.so.575.57.08 compat-cuda129/
cp NVIDIA-Linux-aarch64-575.57.08/libnvidia-ptxjitcompiler.so.575.57.08 compat-cuda129/
cd compat-cuda129
ln -s libcudadebugger.so.575.57.08 libcudadebugger.so.1
